ODIN for Azure Local

Version 0.21.04 - Available here: https://aka.ms/ODIN

A comprehensive web-based wizard to help design and configure Azure Local (formerly Azure Stack HCI) architectures. This tool guides users through deployment scenarios, network topology decisions, security configuration, and generates a cluster design document and an ARM parameter file that can be used for automated deployments. The Sizer Tool can be used to provide example cluster hardware configurations, based on your workload scenarios and capacity requirements, and it includes a 3D visualization of the hardware.

Disclaimer: This tool is provided as-is without Microsoft support. This is an experimental project to help customers accelerate their skills ramp up for Azure Local, while helping IT architects to validate desired configurations.

🎉 Version 0.21.04 - Latest Release

Adds Foundry Local on Azure Local (Preview), Edge RAG Preview, enabled by Azure Arc, and Azure AI Video Indexer enabled by Arc (Preview) as three new top-level workload types in the Sizer, alongside Azure Local VMs, AKS Arc, and AVD. All three run on AKS Arc; Foundry Local sizes per-replica model serving, Edge RAG sizes a turnkey 4-VM Retrieval Augmented Generation pipeline (LLM + embeddings + vector DB) driven by the user's document corpus size, and AI Video Indexer sizes Microsoft's published Minimum / Recommended cluster-wide tiers for video and audio analysis on edge devices. Closes issue #213.

sizer/ — new "Foundry Local" workload type

  • Fourth workload-type-btn on the Sizer page, with a dedicated modal for sizing AI inference deployments.
  • Model size classes with conservative per-replica resource estimates: Small SLM (Phi-3.5-mini, Llama-3.2-3B — 4 vCPU / 8 GB / 20 GB), Medium SLM (Phi-4, Mistral-7B, Llama-3.1-8B — 8 vCPU / 16 GB / 40 GB), Large LLM (DeepSeek-R1-Distill-32B, Llama-3.3-70B Q4 — 16 vCPU / 64 GB / 100 GB), and Custom.
  • Inference engine picker — ONNX-GenAI (CPU or GPU) or vLLM (GPU only). Selecting vLLM forces GPU mode (DDA) and disables the None option.
  • Replicas input (1–100). Each replica is sized to the model class and reserves a fixed 200 GB AKS Arc OS disk per worker node.
  • Total sizing = 3-node Kubernetes control plane (3 × 4 vCPU / 8 GB / 200 GB OS each) + N replicas × per-replica resources + 200 GB OS disk per replica + 2 vCPU / 4 GB inference operator overhead.
  • Preview pill + inline link to request preview deployment access.

sizer/ — new "Edge RAG" workload type

  • Fifth workload-type-btn on the Sizer page, with a dedicated modal for sizing Edge RAG Preview, enabled by Azure Arc — Microsoft's turnkey on-premises Retrieval Augmented Generation pipeline.
  • Compute mode — GPU mode (recommended) = 4 × NC8_A2 / NC8_A16 worker VMs (8 vCPU / 32 GB / 1 GPU each), or CPU mode = 4 × D8s_v3-equivalent worker VMs (8 vCPU / 32 GB each). Numbers come straight from Microsoft's published Edge RAG hardware requirements. Switching modes auto-toggles the standard GPU controls (DDA on / off).
  • Document Corpus Size (GB) — drives a vector-database storage allowance of corpusGB × 1.5 (chunks + embeddings + index).
  • Total sizing = 3-node AKS Arc control plane + 4 worker VMs + vector-DB storage + 2 vCPU / 4 GB Edge RAG operator overhead. The modal displays this composition inline.

sizer/ — new "AI Video Indexer" workload type

  • Sixth workload-type-btn on the Sizer page, with a dedicated modal for sizing Azure AI Video Indexer enabled by Arc (Preview) — Microsoft's video and audio analysis pipeline (transcripts, OCR, faces, objects, topics, sentiment) running on AKS Arc.
  • Configuration picker — Recommended (2 worker nodes / 64 vCPU / 256 GB / 100 GB cluster-wide PV storage, HA-capable) or Minimum (1 worker node / 32 vCPU / 64 GB / 50 GB) — values from Microsoft's published minimum hardware requirements.
  • GPU optional — Video Indexer's default Phi LLM is CPU-bound; GPU is only needed if you bring your own GPU-bound model. DDA only.
  • ReadWriteMany storage class required — modal hint links to Azure Container Storage enabled by Arc as the recommended option.
  • Total sizing = 3-node AKS Arc control plane + 1–2 worker nodes sized per Microsoft's cluster-wide totals + 2 vCPU / 4 GB operator overhead.
  • Gated Preview — modal includes a link to request subscription registration.

Modern Preview banner + descriptive hover tooltips

  • Preview banner moved from the inline pill next to the workload name to a small, animated badge in the top-left corner of each Preview workload-type button (Foundry Local, Edge RAG, AI Video Indexer). Subtle blue→purple gradient with a soft pulsing glow.
  • Descriptive hover tooltips on every workload-type button (all six). Replaces the native browser title= attribute with a styled, multi-line tooltip card (1-second hover delay). Expands acronyms (AKS = Azure Kubernetes Service enabled by Arc; AVD = Azure Virtual Desktop; RAG = Retrieval Augmented Generation) and gives a one-paragraph summary of what each workload provides.

Round-trip + tests

  • All three new workload types serialize/deserialize through the existing JSON Export, JSON Import, share URL, Configure in Designer hand-off, and Configuration Report (Markdown + HTML + PowerPoint) — same code paths VMs / AKS / AVD use.
  • 26 new unit tests in tests/index.html (13 for Foundry, 6 for Edge RAG, 7 for AI Video Indexer) covering preset integrity, control-plane + worker + operator overhead arithmetic, custom-override paths, vector-DB scaling, per-tier arithmetic, and GPU count calculation.

Other UX polish bundled in this release

  • Sizer AUTO sizing now enforces a 24-core CPU minimum per node when GPUs are involved on multi-node clusters (Low Capacity remains capped at 14 cores). Manual CPU overrides still win.
  • Sizer: fixed misleading "Auto-configured N node(s) based on undefined requirements" message that appeared when GPU was the bottleneck (added the gpu: 'GPU' label).
  • Sizer Foundry Local model class examples now lead with OpenAI gpt-oss models — Medium SLM lists OpenAI gpt-oss-20b first; Large LLM lists OpenAI gpt-oss-120b first.
  • Configuration Report now renders Video Indexer as AI Video Indexer in the Markdown / HTML / PowerPoint exports.
  • 3D rack visualization on mobile: hidden the "Azure Local" brand badge overlay on viewports ≤ 768 px so it no longer overlaps the rack.
  • Top navigation tab order changed to: Knowledge | Sizer | Designer | ToR Switch. Single source of truth in js/nav.js — affects every page.
  • Knowledge tab: Microsoft Sovereign Private Clouds Reference Architectures is now the first item in the left-hand navigation menu and the default page that loads.
  • Reference Architectures page — new "Share Architecture as URL" button, mirroring the Sizer's pattern. Encodes purposes / connectivity / tenancy / scale / storage selections into a base64 ?config= URL, copies it to the clipboard, and shows recipients a green confirmation banner. URL-load path validates every property key against the known PURPOSES whitelist (rejects __proto__ / constructor / prototype) before writing to state.

Notes

  • Per-replica, per-corpus, and per-tier resource estimates are conservative rules of thumb. Foundry Local on Azure Local, Edge RAG Preview enabled by Azure Arc, and Azure AI Video Indexer enabled by Arc are all in Preview; sizing depends on the specific model, quantization, batch size, document mix, chunking strategy, embedding model, video volume / resolution / codecs, concurrent jobs, and ReadWriteMany volume performance. Validate with your OEM hardware partner.
  • No new external network calls. No new third-party CDN dependencies. Foundry, Edge RAG, and AI Video Indexer workload state lives in localStorage and the existing share-URL / JSON-export pipeline, exactly like the other three workload types.

Best Practices

Using the Wizard

  1. Review Prerequisites - Click "Prerequisites" before starting
  2. Try Templates - Load a pre-built template for common scenarios
  3. Save Progress - Export configuration at major milestones
  4. Validate Early - Use real-time validation to catch errors
  5. Use Calculator - CIDR calculator helps avoid subnet conflicts

Network Planning

  1. Document IP Ranges - Keep track of all CIDRs and ranges
  2. Avoid Overlaps - Use CIDR calculator to verify no conflicts
  3. Plan for Growth - Size infrastructure pool with headroom
  4. Test DNS - Verify DNS resolution before deployment
  5. Review Gateway - Ensure default gateway is outside IP pools

Configuration Management

  1. Export Regularly - Save configuration at each major decision
  2. Version Control - Keep exports with version tags
  3. Share with Team - Use export/import to collaborate
  4. Document Changes - Note modifications in separate doc
  5. Backup Configs - Store exports in version control system

Security Considerations

Input Sanitization

  • All user inputs are sanitized using escapeHtml() and context-specific sanitizers
  • CIDR and IP validation prevents injection attempts
  • File imports are validated for correct structure

Data Storage

  • All data stored in browser localStorage (client-side only)
  • No data transmitted to external servers
  • Clear localStorage on shared computers

Best Practices

  • Don't include sensitive credentials in configurations
  • Don't share exports containing private IP ranges publicly
  • Review imported configs before applying
  • Use prerequisites checklist to verify security requirements

Published Site Surface Area

The live site at https://azure.github.io/odinforazurelocal/ is published via GitHub Pages (Jekyll). The root _config.yml excludes local-only folders from publication to keep the public surface minimal:

  • tools/ — Playwright demo video recording (local dev only)
  • scripts/ — Node.js build / export / generator scripts
  • tests/ — local test harness
  • test-results/ — CI output artifacts
  • docs/archive/ — historical markdown not linked from the site
  • node_modules/, package*.json, lint configs, CONTRIBUTING.md

The source of these files is still visible on GitHub — this is a surface-reduction measure, not a secrecy measure.

Demo Video Tooling (Playwright)

The tools/ folder contains scripted Playwright demos for producing short walkthrough videos (e.g. for LinkedIn or the README). Playwright is Apache 2.0 licensed, a devDependency only, and never runs on the published site. See tools/README.md for setup and safety rules. Demo scripts must only target http://localhost:5500 and must not include credentials or real tenant data.

Version 0.21.x Series (May 2026)

0.21.03 - Microsoft Sovereign Private Clouds reference architectures (Preview)

New Microsoft Sovereign Private Clouds reference architectures page (Preview) in the Knowledge tab. Pick a business purpose, see a live SVG diagram of the resulting architecture, and download an editable multi-slide PowerPoint generated entirely client-side via JSZip.

  • docs/reference-architectures/ — new self-contained Knowledge-tab page with five business purposes (Azure Local, Microsoft 365 Local, GitHub Enterprise Local, Azure Virtual Desktop on Azure Local, Foundry Local), connectivity / tenancy / topology pickers, a live SVG preview, an About this architecture narrative section, and an editable client-side PowerPoint export (Cover, Diagram, Control Plane, Summary, and per-purpose slides) generated via JSZip 3.10.1 (MIT, vendored at vendor/jszip-3.10.1.min.js).
  • Independent of the Designer: this page does not read or modify your Designer / Sizer / Switch Configuration state.
  • No new external network calls — all icons, the cover logo, and the deck assembly happen client-side. docs/Temp/ added to .gitignore and _config.yml exclude list as defence-in-depth so the local working folder for source decks / extracted PPTX content (which may contain internal Microsoft reference material) can never be committed and can never be published via Jekyll.

0.21.02 - Security & Code-Quality Hardening

Security- and code-quality-hardening release. Resolves the 12 open CodeQL code-scanning alerts on the repository (1 × js/xss-through-dom, 11 × js/remote-property-injection) and the 8 open AI-generated Code Quality findings. No user-visible behaviour changes.

  • CodeQL js/xss-through-dom (Sizer JSON Import preview, alert #15) — parseAndPreviewClusterJSON() now coerces every JSON-derived numeric value (coreCount, coresPerSocket, sockets, memoryGiB) to Number() immediately before they are interpolated into the preview HTML, making the type-narrowing barrier explicit on the data-flow path from <textarea>.value → JSON.parse(...) → previewDiv.innerHTML. String values were already escaped via escapeHtml().
  • CodeQL js/remote-property-injection (alerts #16–#26) — eleven sites where the code wrote to a JS object using a key derived from user-supplied data (NIC speed strings, network-zone names, intent assignments, drag-and-drop port IDs) hardened against prototype-chain pollution. Ten dictionaries are now created via Object.create(null) (bySpeed / bySpeed2 in report/pptx-export.js; groupsByZoneD / zoneLeafCountersD / buckets / groupsByZone / zoneLeafCounters in report/report.js). The remaining one (state.disaggAdapterMapping[portId] in js/disaggregated.js) validates portId against getDisaggPortList() before using it as a property key.
  • AI Code Quality findings cleared — js/stats-bar.js (STAT_PLACEHOLDER constant); scripts/smoke-test-pptx.js (size error message); switch-config/index.html (Arizona option tag); tools/demos/generate-disagg-fc-deck.spec.js (dialog auto-accept logging); tools/demos/odin-full-walkthrough.spec.js (configurable slowMo via ODIN_DEMO_SLOWMO, stable [onclick*="'aks'"] / [onclick*="'vm'"] selectors).

0.21.01 - Sizer mobile + Rack U / Power fixes

Closes #210 — Sizer: Formatting issue when using a mobile device to view sizer.

  • Sizer — Mobile layout fix (iOS / narrow viewports) (#210): Sizer no longer overflows horizontally on iPhone (390px) or other narrow screens. Root cause was the CPU Generation <select> (~353px intrinsic width for "Intel® 4th Gen Xeon® (Sapphire Rapids)") holding the .sizer-layout 1fr CSS Grid track open, plus flex containers (.section-header-row, .config-row, .export-actions) that didn't wrap. Fixed in sizer/sizer.css with min-width: 0 on the panels, max-width: 100% on .config-row select, flex-wrap: wrap on the three flex rows, and removal of the mobile-only padding: 0 25px indents on <header> / .disclaimer-wrapper / .sizer-footer from PR #170. Verified at 390 / 768 / 1024 / 1400 px. Lightning-bolt icon next to Estimated Power, Heat & Rack Space per Instance now rendered filled in --warning amber (#f59e0b).
  • Sizer Rack U / power: BMC switch now counted in non-disaggregated clusters: Rack-Unit estimate and Network Infrastructure Power now correctly include 1 × 1U BMC switch per rack for Single-node, Standard Hyperconverged, and Rack-Aware deployments — matching what the 3D rack visualization has always rendered. Single-node = 3U / 150W infra (was 2U / 0W); Standard HCI (1 rack) = nodes × 2U + 3U switches / 650W infra; Rack-Aware (2 racks) = nodes × 2U + 6U switches / 1,300W infra. Power-detail expander now lists ToR and BMC as separate line items.
  • Sizer — Low Capacity: Rack U / Power now reflect compact edge hardware: Per Microsoft's networking requirements for low-capacity systems, Low Capacity does not require a separate BMC switch and uses at most 1 small edge switch. Cell relabelled to "Hardware Footprint" with value "Tabletop — N appliances + 1 switch" (or "Tabletop — standalone appliance" for 1 node) — no U figure, since Low Capacity is not rack-mounted. Infra power corrected: 0W single-node, 50W multi-node (was 650W — ~13× too high).
  • Sizer — Rack Units cell now uses an expandable breakdown with chevron ▸ next to the value (no more text overlap). Keyboard-accessible (<button> with aria-expanded / aria-controls), hidden for Low Capacity.
  • Sizer — Capacity Usage for Workload matches Low Capacity's 3-node limit: top progress bar now shows "Azure Local low capacity instance size" / 3 max for Low Capacity (was / 16 Hyperconverged default).
  • Sizer — Disaggregated rack-U: external SAN appliance no longer counted. Server nodes, ToR, BMC, and FC switches are still counted; the breakdown now ends with "External SAN storage appliance(s) are not counted — consult your SAN vendor for actual rack-U."

🎉 Version 0.20.x Series (April 2026)

0.20.67 - Security & Code-Quality Release

  • Sizer JSON Import fixes (#207): CPU sockets now respected from machine JSON (was always forced to 1); per-socket vs total cores reconciled correctly (a 2×10 = 20-core ASEPRO2 machine no longer shows up as 20 × 1 socket); 1-node imports auto-switch Deployment Type to Single Node; resiliency auto-upgrades to Three-way Mirror for 3+ node imports; new Hyperconverged vs Rack-Aware prompt with machine-count validation; "Apply Configuration" renamed to "Load Cluster Configuration"; memory dropdown preserves non-standard DIMM totals via a custom option (e.g. 80 GB); S2D capacity-disk count and size captured in the import preview and applied to both single-tier and tiered selectors; 5.68 TB SSD added to all capacity-disk dropdowns; re-clicking Parse & Preview no longer resets in-preview selections. 30 new regression tests cover all of the above.
  • No other end-user feature changes. Tightens the build, dependency, and CI surface so future work is safer to land.
  • All third-party JS libraries vendored locally (vendor/html2canvas-1.4.1.min.js, vendor/jspdf-4.2.1.umd.min.js, vendor/three-0.128.0.min.js, vendor/three-OrbitControls-0.128.0.js). Designer, Sizer, and Configuration Report no longer fetch any runtime JavaScript from cdn.jsdelivr.net. Firebase analytics (loaded from gstatic.com) is unchanged.
  • CSS lint added to CI (stylelint with custom-property-no-missing-var-function and color-no-invalid-hex).
  • CodeQL security scanning workflow added (.github/workflows/codeql.yml) — runs security-and-quality queries on every PR and weekly.
  • npm audit --audit-level=high added as a CI gate. basic-ftp override bumped to >=5.3.1 to clear advisory GHSA-rp42-5vxx-qpwr.
  • PPTX export smoke test added (scripts/smoke-test-pptx.js) — verifies the PowerPoint export produces a valid OOXML file end-to-end.
  • Code-quality cleanup: silent catch (e) {} blocks documented or replaced with console.warn; deprecated CSS keywords (word-break: break-word, page-break-inside: avoid) replaced with modern equivalents; unreferenced docs/outbound-connectivity/styles_backup.css removed.
  • ESLint convention documented in docs/ESLINT_CONFIG_NOTES.md.
  • Tab navigation reordered to Designer | Sizer | ToR Switch | Knowledge so the three "doing" tabs sit together first, with the reference / docs tab last.
  • ToR Switch page parity fixes: stat tiles now populate (was missing js/utils.js), and the page header now matches Designer / Sizer (logo, version, What's New link, disclaimer banner).
  • First-visit walkthrough + Help button on the ToR Switch page: a 3-step Welcome / Generator / QoS Validator overlay appears once on first visit (gated by localStorage), and the shared nav-bar Help (?) button now re-launches the same overlay on demand from the ToR Switch tab.
  • New "Workloads" slide in the PowerPoint export of the Configuration Report: when the report was started from the Sizer, the generated PPTX now includes a dedicated Workloads slide (right after Node Configuration) with one bullet per VM / AKS Arc / AVD workload plus a Subtotal sub-bullet. The slide is automatically skipped for non-Sizer reports.
  • PowerPoint slide "Rack Configuration" renamed to "Node Configuration" — the slide content is per-node hardware (CPU, memory, disks, resiliency, cluster type), so the new title describes what it actually shows.
  • Designer “Start Over” now fully resets state. Previously the reset missed sizerHardware / sizerWorkloads (so Sizer-imported workloads carried over), architecture, and all disaggregated fields. Defaults are now driven from a single source-of-truth factory so adding new state can’t silently bypass Start Over. Theme and font-size preferences are still preserved across a reset.
  • Sizer "Estimated Power, Heat & Rack Space per Instance" panel is now always visible — previously it was hidden until the first workload was added, even though the figures only depend on the selected hardware and node count. Power, BTU/hr, and rack-unit estimates (plus the 3D rack visualization) now render with real values from the moment you open the Sizer, so you can compare the data-centre footprint of different hardware choices before any workload is defined.
  • Sizer Power & Heat estimates now flow into the Designer report and PowerPoint export. When you click Configure in Designer from the Sizer, the computed power numbers (per-node Watts, total Watts, BTU/hr, rack U, network infrastructure power, per-node component breakdown) are now carried through to report.html as a new Power, Heat & Rack Space (from Sizer) section and to a dedicated PPT slide of the same name.
  • Single-rack hyperconverged rack diagram in the Designer report no longer renders gigantic. A tall+narrow rack (e.g. 1 rack × 16 nodes) was being stretched to fill the parent card by default browser SVG sizing, making the title and node tiles many times their natural size. The diagram now caps its upward scaling at the natural intrinsic SVG width while still shrinking on narrow viewports.

0.20.09 - Configuration Report: PowerPoint Export

  • 📊 Download PowerPoint button on the Configuration Report page generates a styled .pptx deck (template-driven via report/template/OdinPPTTemplate.potx).
  • Slide coverage: Deployment Scenario & Scale, Physical Network, Rack Configuration, Leaf & Spine Architecture, AKS Reachability & Routing Hops, Host Networking & Intents, Outbound Connectivity, Proxy, Security Configuration, Private Endpoints, Infrastructure Network — with a hero cover and closing slide.
  • Microsoft Learn reference hyperlinks per network pattern (FC no-backup / FC with backup / single-node / 2-node switchless / 3-node switchless / 4+ switchless / 2-node switched / 3+ switched), plus dedicated links for Private Endpoints and Arc Gateway.
  • Visual extras: ✓/✗ run coloring on the Security slide, red callout banner where Arc Private Link is unsupported, footer subnet-utilisation raster on Infrastructure Network, rack diagram on Physical Network.
  • Client-side only: PPTX is generated in the browser via vendored JSZip — no telemetry, no backend, works offline.

0.20.08 - Disaggregated: iSCSI 4-NIC physical paths

  • iSCSI 4-NIC physical shared paths in host-networking diagrams (wizard preview + report 2-node view): NIC3/NIC4 stay standalone physical adapters carrying Cluster A/B and iSCSI Path A/B with no SET, no vSwitch, and no host vNICs.
  • 6-NIC + Backup correction: ClusterBackupSwitch remains only for Cluster/Backup on NIC3/NIC4; dedicated iSCSI remains on NIC5/NIC6.
  • Shared vs dedicated iSCSI overrides: 4-NIC iSCSI derives from Cluster A/B VLAN/subnet values. Dedicated iSCSI A/B override cards appear only for iscsi_6nic, including 6-NIC + Backup.
  • Dedicated iSCSI defaults updated to VLAN 300 / 400 and subnets 10.30.30.0/24 / 10.40.40.0/24.
  • vNIC label readability remains for layouts that genuinely render host vNICs, such as Management + Compute and 6-NIC + Backup Cluster vNICs.

0.20.07 - Knowledge Tab: Context-Aware Help Button

  • Knowledge Help button: The nav-bar Help button on the Knowledge tab now shows a dedicated walkthrough for whichever sidebar topic is active — the Outbound Connectivity Architecture Guide (same-origin written reference) or AzLoFlows (external interactive diagram builder). Previously it fell through to the Designer onboarding because the original same-origin flow-diagram pages were replaced by AzLoFlows and the cross-origin contentWindow.showFlowOnboarding() probe in nav.js could no longer reach the embedded page.
  • Removed orphan pages: docs/outbound-connectivity/azure-local-public-path-dark-flows.html and azure-local-private-path-dark-flows.html were no longer linked from anywhere after the AzLoFlows integration.

0.20.06 - Disaggregated Architecture, ToR Switch Config Generator & QoS Validator

  • Disaggregated Architecture Wizard: New end-to-end wizard for disaggregated deployments with external SAN storage (Fibre Channel, iSCSI 4-NIC, iSCSI 6-NIC) and Clos leaf-spine fabric — up to 64 nodes across multiple racks, with VLAN/VNI/VRF configuration, QoS policy, IP planning, drag-and-drop NIC-to-intent mapping, breadcrumb navigation, and interactive SVG rack topology diagrams
  • ToR Switch Config Generator & QoS Validator: Full-featured switch configuration page for Cisco NX-OS and Dell OS10 platforms — generates ToR, BMC, and border switch configs with rack-aware 4-ToR support, infrastructure token replacement, JSON export. Paste a show running-config (Cisco) or show running-configuration (Dell OS10) to validate PFC, ETS, ECN, MTU 9216, system QoS policy, and interface-level PFC/trunking against Azure Local requirements
  • Cisco Nexus 93108TC-FX3P as ToR: Added 10GBASE-T copper switch model as a ToR option (in addition to existing BMC role)
  • Per-Rack Site / Location: Rack-aware deployments support separate Site / Location for Rack 1 and Rack 2 (SNMP location)
  • Report: 2D SVG Rack Diagram: Static front-view SVG rack diagram with server nodes, ToR/BMC switches, core switch box, rack-aware layout, contiguous node numbering, Azure Local branding, legend, and downloadable SVG
  • 3D Rack Viz Improvements: Azure Local branding, BMC switch in every rack, dark grey ToR color, single-node topology, label cleanup
  • Designer: Management VLAN guidance: Improved VLAN option descriptions and expanded info box
  • Designer → Switch Config: "Generate / Validate ToR Switch Configuration" button opens switch config page in new tab
  • Sizer: Disaggregated Storage: New deployment type with rack count (1–4), spine switch count (2/4), storage connectivity (FC/iSCSI), multi-rack 3D visualization with FC switches and per-rack uplinks
  • Sizer: Designer → Sizer Transfer: Disaggregated architecture transfers with rack count, spine count, and storage type
  • Sizer: Import/Export: Disaggregated state persisted in save, resume, and JSON import/export
  • QoS Validator: Smart PFC detection using QoS service-policy, dynamic CoS value detection, actionable warning messages

🎉 Version 0.18.x Series (March 2026)

0.18.04 - Sizer: 3D Rack Visualization

  • 3D Rack Visualization: Interactive 3D preview of the estimated rack layout using Three.js (MIT) — renders 42U open-frame server cabinets with detailed 2U server nodes (disk bays with pull handles, status LEDs, Azure logo, dual PSUs, network ports, BMC port, ventilation grille) and 1U ToR switches (48-port ethernet in two rows, QSFP uplinks, fan vents)
  • Rack-Aware Support: Rack-aware deployments render two side-by-side cabinets with balanced node distribution, blue core switch/router above racks
  • Network Topology: Rack-aware view includes management/compute uplink cables (blue) from each ToR to the core router, SMB storage trunk cables (pink) between cross-rack ToR pairs, and LAG inter-switch links (orange) between paired ToRs in each rack

0.18.03 - ARM Parameters: Fix Custom Location Name (#189)

  • Fix Custom Location Name (#189): Fixed a bug where the "Custom Location Name" input field on the ARM Parameters page was not updating the customLocation value in the generated parameter JSON — the update code referenced a mismatched key (customLocationName instead of customLocation)

0.18.02 - Designer: Fix NIC overrideAdapterProperty (#187)

  • Fix NIC overrideAdapterProperty (#187): Fixed a bug where disabling RDMA on NICs assigned to the Management+Compute intent (e.g., in a switchless 4+ NIC configuration) would generate "overrideAdapterProperty": false in the ARM parameter JSON instead of true
  • NIC-Level RDMA Detection: The ARM intent generator now detects NIC-level RDMA changes made at Step 07 (Port Configuration) and correctly sets the override flag
  • Auto-Disable Flag: When Step 08 (Intent Overrides) auto-disables RDMA for an intent group because no NICs are RDMA-capable, the adapter property touched flag is now set

0.18.01 - Sizer: GPU Capacity Planning & Total VM Requirements

  • Sizer: GPU Capacity Planning (#180): Full GPU capacity planning based on workload requirements — supports DDA (Discrete Device Assignment) and GPU-P (GPU Partitioning) modes across Azure Local VMs, AKS Arc, and AVD workloads
  • GPU Model Selectors: DDA and GPU-P modes include GPU model dropdowns that auto-set hardware GPU type and enforce homogeneous configuration across all workloads and nodes (with WORKLOAD badge on locked hardware GPU Type)
  • Per-Model GPU-P Partitions: GPU-P partition sizes dynamically filter based on the selected GPU model, showing VRAM per partition (e.g., A2 supports up to 1:8 / 2 GB, L40S supports up to 1:16 / 3 GB)
  • GPU Capacity Bar: New GPU capacity bar chart showing consumed vs available GPUs with N−1 node awareness for maintenance/drain reserve
  • GPU Auto-Scaling: GPU demand drives node count recommendations and GPUs-per-node auto-scaling (with AUTO badge) up to each model's physical maximum
  • GPU Models Expanded: Added NVIDIA T4 (16 GB, 70W, max 2/node), RTX Pro 6000 (48 GB, 600W, max 2/node), H100 (80 GB, 700W, max 2/node) with correct maxPerNode, DDA/GPU-P support flags, and AKS compatibility
  • AKS GPU VM Sizes: AKS workloads show all supported GPU-enabled VM SKUs (T4, A2, A16, L4, L40, L40S, RTX Pro 6000) with fixed vCPU/memory per size — auto-sets hardware GPU type on selection
  • GPU Badge: Workload cards show a yellow "GPU" badge when GPU-enabled
  • GPU Threshold Warnings: GPU ≥90% triggers over-threshold warnings, sizing notes, and blocks Designer export — includes notes for physical capacity exceeded vs N−1 capacity exceeded
  • GPU in Reports: GPU utilization flows through to Sizer Word export, Designer, and Report Generator
  • Knowledge Links: GPU Requirements sections include links to Microsoft documentation for supported GPU models (Azure Local VMs, AKS Arc) and GPU-P management guide
  • Sizer: Total VM Requirements (#181): New "Total VM Requirements" input mode — allows users to enter aggregate vCPU, memory, storage, and GPU totals directly without per-VM multiplication
  • 3:1 vCPU Overcommit Ratio: Added the missing 3:1 option to the vCPU overcommit ratio dropdown

🎉 Version 0.17.x Series (February - March 2026)

0.17.61 - Sizer: Fix Resume Session Banner

  • Fix Resume Banner: Fixed the "Previous Sizer Session Found" banner appearing unconditionally on every page load, even when no workloads were added — the banner now only appears when there are actual workloads to resume (fixes #178)
  • Fix Start Fresh Re-Save: Fixed "Start Fresh" immediately re-saving default state, causing the banner to reappear on the next page load

0.17.60 - Sizer: Intel® 6th Gen Xeon® (Granite Rapids / Sierra Forest)

  • Intel® 6th Gen Xeon® Expanded: Expanded the Intel® 6th Gen Xeon® CPU generation in the Sizer to cover the full 8–172 core range from the Azure Local hardware catalog
  • Updated Intel Default: Intel CPU default changed from 5th Gen Xeon® (Emerald Rapids) to Intel® 6th Gen Xeon® (Granite Rapids / Sierra Forest)

0.17.58 - Mobile Layout Fixes & Consistency

  • Sizer Mobile Alignment: Fixed header, disclaimer banner, stats bar, and Privacy footer not visually aligned with form panels on iOS mobile devices — added matching horizontal padding on mobile
  • Sizer Footer Fix: Moved Privacy footer inside the container element so it respects max-width and aligns with page content
  • Designer Step-Header Overflow: Fixed "Unsure? Start with Sizer" button overlapping Step 04 (Cluster Configuration) header on narrow mobile screens — step-header now wraps and sizer-link drops to its own line
  • Sizer Mobile Header Consistency: Aligned logo size (80px), version text size (11px), and logo ordering (logo above title) with the Designer's mobile layout
  • Designer Title Update: Renamed from "Odin for Azure Local" to "ODIN Designer for Azure Local" for naming consistency with the Sizer
  • CSS Nesting Fix: Corrected CSS for hover and active states of .stat-value elements so styles apply consistently across browsers

0.17.57 - Individual MANUAL Override Dismiss

  • Per-Field Dismiss: Each MANUAL badge now includes a small × button to remove that individual override without clearing all overrides
  • Shared Flag Handling: CPU-related badges (cores, sockets, manufacturer, generation) are linked — dismissing any one clears all four
  • Remove All Button Renamed: Button renamed to "Remove all MANUAL overrides" for clarity
  • Auto-Scale on Dismiss: Dismissing a MANUAL override immediately triggers auto-scaling — the field reverts to an optimal value and receives the purple AUTO badge

0.17.56 - Designer-to-Sizer Transfer

  • Designer-to-Sizer Transfer: New "⚖️ Sizer: Add Workloads to this Cluster" button at the bottom of the Designer — transfers deployment type and node count to the Sizer; enabled once Deployment Type and Nodes are selected
  • Sizer: Designer Import: Sizer accepts configuration from the Designer — pre-populates cluster type and node count with a confirmation banner; skips saved session prompt when importing from Designer
  • Sizer: MANUAL Node Lock: Node count from Designer locked as MANUAL — prevents auto-scaling from resizing the cluster
  • Sizer: Workload Persistence: Prior Sizer session workloads restored on return from Designer; banner shows restored count

0.17.55 - Navigation Consistency, Sizer ALDO Workload Cluster, Header Redesign & Analytics

  • Navigation: Tab-Based Routing: All top navigation links now use ?tab= URL parameters for consistent tab switching; parameters cleaned after processing via history.replaceState
  • Navigation: Designer Link Bug Fix: Fixed intermittent bug where clicking Designer from Sizer navigated to Knowledge tab — stale sessionStorage combined with missing ?tab=designer parameter
  • Knowledge Tab: Session Popup Fix: Fixed "Previous Session Found" popup appearing incorrectly on the Knowledge tab
  • Knowledge: Flow Diagram Backgrounds: Flat dark backgrounds (#111111) replacing animated stars/space WebGL effects on Public and Private Path flow diagrams
  • Knowledge: Public Path Layout: Shifted diagram elements down to prevent overlap with the Architecture navigation bar
  • Sizer: ALDO Workload Cluster: New deployment type integrating disconnected scenario with workload cluster role; prompts for Autonomous Cloud FQDN before transfer; skips region picker
  • Sizer: Deployment Type Rename: Renamed "Cluster Type" to "Deployment Type" throughout the Sizer
  • Sizer: Header Redesign: Restructured Sizer header to match Designer layout — centered title, absolutely-positioned logo, and Firebase analytics stats bar
  • Sizer: Disclaimer Banner: Added disclaimer banner matching the Designer's warning banner
  • Sizer: Preview Badge Removed: Removed purple "Preview" badge from Sizer navigation link
  • Sizer: Analytics Fix: Fixed page view statistics not loading — added missing utils.js dependency and fallback fetchAndDisplayStats() call
  • Sizer: Title Update: Changed page title to "ODIN Sizer for Azure Local" with updated description
  • Sizer: Configure in Designer Fix: Fixed "Configure in Designer" navigating to Knowledge tab — added ?tab=designer to navigation URL

  • Knowledge Tab: Interactive Diagrams: Added interactive WebGL flow diagrams for Public Path and Private Path outbound connectivity, selectable via a left sidebar

0.17.10 - ALDO Management, IRVM1 Auto-Workload, ARB Overhead, Region Picker & Sizer Report

  • Sizer: ALDO Management Cluster Type: New cluster type — fixed 3-node, all-flash, three-way mirror configuration for ALDO management scenarios; node count locked at 3, storage forced to all-flash, resiliency locked to three-way mirror
  • Sizer: ALDO Minimum Hardware Enforcement: Automatically enforces documented ALDO minimums — 96 GB memory, 24 physical cores, and 2 TB SSD/NVMe storage per node; 64 GB/node (192 GB total) reserved for the disconnected operations appliance VM and deducted from workload capacity; 960 GB boot disk recommended in sizing notes
  • Sizer: ALDO IRVM1 Auto-Workload: Fixed infrastructure workload (IRVM1 — 24 vCPUs, 78 GB memory, 2 TB storage) automatically added when ALDO Management Cluster is selected; Add Workload buttons disabled, workload cannot be edited/cloned/deleted; ALDO cores auto-scale floor enforces 24 physical cores minimum
  • Sizer: ARB Overhead: Azure Resource Bridge appliance VM (8 GB memory, 4 vCPUs per cluster) deducted from available capacity in sizing calculations and capacity bars; consolidated infrastructure overhead sizing note
  • Sizer: MANUAL Override Badges: Green "MANUAL" badge on any user-edited hardware dropdown — persists across workload add/edit/delete/clone with amber capacity warning when overrides prevent auto-scaling; "Remove MANUAL overrides" button to clear all locks
  • Sizer: Independent Disk Locks: Disk size and disk count are independently lockable — manually setting one still allows auto-scaling on the other
  • Sizer: Region Picker: Region selection modal in Sizer before navigating to Designer — Azure Commercial (8 regions) and Azure Government (1 region) toggle; prevents cascade reset that wiped imported cluster configuration
  • Sizer: Three-Way Mirror for 3+ Nodes: Standard clusters with 3 or more nodes are now locked to three-way mirror only — two-way mirror option removed for 3+ node configurations
  • Sizer: Sizing Notes: Replaced "RAM" with "memory", updated boot drive text, added spacing around × in storage layout notes, added ALDO knowledge link
  • Report: Sizer Hardware & Workloads: Full "Hardware Configuration (from Sizer)" section now rendered in the HTML report; new "Workloads (from Sizer)" section shows per-workload details (VM, AKS, AVD) with subtotals; individual workloads transparently passed through Sizer → Designer → Report
  • Report: AKS Arc Network Requirements: Port/VLAN requirements table (ports 22, 6443, 55000, 65000) shown when AKS workloads are configured, with link to MS Learn documentation
  • Report: Disconnected Network Link: "Plan your network for disconnected operations" link shown in Connectivity section for disconnected deployment types
  • Report: Firewall Allow List: Added Firewall Allow List Endpoint Requirements row to the report Connectivity section
  • Designer: Edge 2-Node Switchless Default Gateway: Fixed the Default Gateway field being empty and disabled — template was using DHCP which caused the gateway field to be disabled; changed to static IP with gateway 192.168.100.1
  • Sizer: Tiered Storage Fix: Fixed MANUAL badge not appearing on disk size for all-flash configurations — replaced incorrect tiered detection with _isTieredStorage() helper
  • Sizer: ALDO Configure in Designer Fix: "Configure in Designer" for ALDO Management Cluster now correctly selects the Disconnected scenario with Management Cluster role and prompts for Autonomous Cloud FQDN — previously defaulted to Hyperconverged
  • Sizer: ALDO Analytics Tracking: Selecting ALDO Management Cluster now increments the Sizer analytics counter, matching workload addition tracking
  • CI: ESLint Fixes: Added selectDisconnectedOption to ESLint globals, fixed loadTemplate() try-block indentation (4-space → 8-space), changed var to const declarations
  • Sizer: ALDO Cluster Type Switch-Back Fix: Fixed bug where Add Workload buttons (VMs, AKS Arc, AVD) remained disabled and Number of Physical Nodes dropdown stayed greyed out after switching away from ALDO Management Cluster back to Standard or Rack-Aware — renderWorkloads() innerHTML replacement destroyed the #empty-state DOM element, causing a TypeError that halted onClusterTypeChange() before controls could be re-enabled; fixed by caching the element reference at module scope

0.17.04 - Example Template Fix & Regression Tests

  • Example Template Fix (#140): Fixed issue where loading an Example Configuration Template resulted in incomplete wizard progress (67–76%) instead of 100% — all five templates now load fully complete
  • Template Loading Race Condition: Suppressed updateUI() during template loading to prevent cascading auto-defaults (intent, storageAutoIp) and disabled card recalculation between selectOption() calls
  • Template Data Fixes: Corrected ports, intent, arc, rackAwareTorsPerRoom, rackAwareTorArchitecture values across all templates; added missing privateEndpoints, adOuPath, adfsServerName, disconnected fields; removed invalid switchlessLinkMode from Edge template
  • Template DOM Restoration: Fixed AD domain/DNS/OU Path inputs, SDN feature checkboxes, and management card selections not populating after template load due to selectOption() cascade resets
  • Edge 2-Node Switchless: Fixed ports '2'→'4', intent 'all_traffic'→'mgmt_compute', 4-entry portConfig (mandatory for low_capacity + switchless + 2-node); the updateUI() HARD BLOCK was wiping all downstream state
  • Template Regression Tests: Added 46 new CI tests — 5 progress tests, 5 check-count tests, 3 rack-aware zone tests, 5 disconnected template tests, 3 data completeness tests, and 25 updateUI() constraint validation tests

0.17.00 - Disconnected Operations Wizard & Network Diagrams

  • Disconnected Operations Wizard: Full guided wizard for Azure Local disconnected operations — select Management or Workload cluster role, enter Autonomous Cloud FQDN with validation and confirmation gate, choose Air-Gapped or Limited Connectivity outbound mode
  • Disconnected Cluster Role Selection: New D1 step for selecting Management Cluster (fixed 3 nodes, hosts disconnected operations appliance VM) or Workload Cluster (1–16 nodes, connects to management cluster via Autonomous Cloud FQDN)
  • Autonomous Cloud FQDN Endpoint: New D2 step with FQDN input, real-time validation, and confirm/edit gate — all subsequent wizard steps are hidden until FQDN is confirmed
  • Disconnected Context Banner: "Why Azure Cloud & Region are still required" info banner shown for management clusters during and after FQDN confirmation
  • Disconnected Network Diagrams: 26 draw.io diagrams covering all intent configurations (fully converged, disaggregated, mgmt+compute, compute+storage, 4-intent, 4-storage, switchless 2/3/4-node, single-node workload with all intent variants) × 2 outbound modes (Limited Connectivity + Air-Gapped)
  • Single-Node Workload Diagrams: Dedicated diagrams for single-node workload clusters in fully converged (1 intent), mgmt+compute/storage (2 intent), and disaggregated (3 intent) configurations
  • Diagram Routing by Intent: Automatic diagram selection based on cluster role, node count, intent type, storage configuration, port count, and custom NIC assignments
  • DNS Validation Improvements: DNS servers are now validated against node IPs and default gateway to prevent conflicts

🎉 Version 0.16.x Series (February 2026)

0.16.04 - Sizer UI Layout Improvements, Shared Changelog & Bug Fixes

  • Sizer: UI Layout Improvements: ODIN logo and What's New link added to the Sizer header; Reset button moved into the Workload Scenarios section with a confirmation prompt; Save as PDF and Download Word buttons relocated below the Sizing Notes section
  • Sizer: Shared Changelog Module: Extracted the What's New changelog into a shared JavaScript module used by both Designer and Sizer pages
  • Sizer: S2D Resiliency Repair Storage Reservation: 1 × capacity disk per node (up to 4 × capacity disks max) of raw pool space is now reserved for Storage Spaces Direct repair jobs, reducing reported usable storage accordingly
  • Designer: Mobile stats bar 2×2 layout: Page analytics bar on the Designer home page now displays as a 2×2 grid on mobile devices instead of a single row of 4 items
  • Sizer: "Estimated Power, Heat & Rack Space": Updated heading to include "Heat" since the section displays BTU/hr values; power units expanded from "W" to "Watts"; BTU is now a Wikipedia hyperlink
  • Sizer: Mobile layout consistency: On mobile, the Sizer header now matches the Designer page — ODIN logo and What's New centered at top, title and subtitle below
  • Sizer: iOS Safari Mobile Centering: Fixed centering of logo, What's New, and title text on iOS Safari mobile devices
  • Sizer: Mobile Logo & Text Size: Increased logo and What's New text size on mobile for improved readability
  • Sizer: Default 2 Node cluster: Default cluster changed from 3 Node / Three-Way Mirror to 2 Node / Two-Way Mirror, reducing the default starting hardware cost. Three-Way Mirror is automatically selected when 3+ nodes are configured
  • Security: Removed invalid meta tags: Removed X-Frame-Options and X-XSS-Protection meta tags from all pages (HTTP-header-only directives that are ineffective in <meta> tags; X-Frame-Options caused a console warning)
  • Sizer: Node Preference over Ratio/Memory Escalation: The sizer now prefers adding additional nodes before escalating the vCPU-to-pCPU ratio above 4:1 or bumping per-node memory above 2 TB — conservative auto-scaling caps memory at 2 TB and holds ratio at 4:1, with an aggressive pass only when conservative scaling cannot fit workloads
  • Sizer: Auto-Down-Scaling after Aggressive Pass: After the aggressive pass bumps memory or ratio, a node-reduction loop steps the node count back down while keeping utilization under 90%, re-running conservative auto-scale at each step
  • Sizer: Bug Fixes: vCPU ratio AUTO badge persistence, label correction, node recommendation memory cap, stale recommendation message, manual hardware override, node count reset, 1.5 TB memory threshold, memory headroom threshold (80%→85%), bidirectional memory & CPU auto-scaling, sizing notes reorder
  • Sizer: Resiliency Sync after Node Recommendation: Fixed sizing notes showing "Two-way mirror" while the dropdown displayed "Three-Way" — resiliency variables are now re-read after updateNodeRecommendation() changes the dropdown
  • Sizer: Deterministic Node Estimation: Fixed adding future growth (e.g. 10%) reducing the recommended node count — buildMaxHardwareConfig() no longer reads the stale DOM node count to determine the memory cap, ensuring consistent results regardless of previous state
  • Sizer: AMD Auto-Switch before 6:1 Ratio: Before escalating the vCPU-to-pCPU ratio from 5:1 to 6:1, the sizer checks if switching to an AMD CPU generation with more physical cores (e.g. AMD Turin 192 cores/socket = 384 dual-socket) would resolve compute pressure at 5:1, keeping the overcommit ratio lower
  • Sizer: Workload Analytics Tracking: Each new workload added in the Sizer (VM, AKS, or AVD) is now tracked via tracking analytics, to display the "Sizes Calculated" on the main page stats bar
  • Tests: Large Cluster & Scaling Tests: Added comprehensive test suites for node-weight constants, deterministic memory cap, conservative/aggressive auto-scale modes, large cluster node recommendations, node preference verification, and AMD auto-switch before 6:1 ratio

0.16.03 - Custom Intent 8-Port Zone Restrictions

  • Custom Intent 8-Port Zone Restrictions (#130 follow-up): For 8-port custom intent, the wizard now only shows the relevant zones — Management + Compute (required), Compute 1 (optional), Compute 2 (optional), and Storage (required). Removed Management, Compute + Storage, and Group All Traffic zones which are not valid for 8-port configurations.

0.16.02 - Custom Intent 8-Port Compute Intent Fix

  • Custom Intent 8-Port Compute Intent Fix (#130): With 8 ports and custom intent, the wizard now offers two distinct compute zones (Compute 1 and Compute 2) instead of merging all compute ports into a single intent group. The Configuration Report diagram and ARM template correctly reflect the separate compute intents.

0.16.01 - UX Improvements, Power Estimates, Auto-Scale Enhancements & Storage Limit Enforcement

  • Sizer: Standardised Disk Size Dropdown: All disk size inputs replaced with dropdown selects using standard NVMe/SSD capacities (0.96, 1.92, 3.84, 7.68, 15.36 TB), eliminating invalid free-text entries
  • Sizer: Delete Confirmation Dialog: Deleting a workload now requires confirmation, preventing accidental removal
  • Sizer: Clone Workload: New clone button to duplicate a workload with all its settings
  • Sizer: Estimated Power & Rack Space: Per-node power (W), total cluster power, BTU/hr, and rack units (including 2× ToR switches). Based on CPU TDP, memory DIMMs, data + OS disks, GPUs, and system overhead
  • Sizer: AVD Custom Profile Validation: Warns if custom AVD RAM/vCPU or vCPUs/user values fall outside recommended ranges
  • Sizer: Print Stylesheet: Improved print/PDF output — hides config panel, results full-width, page breaks avoided
  • Sizer: Keyboard Accessibility: Escape closes modals; Tab focus trapped inside open modals; first input auto-focused
  • Sizer: OEM Disclaimer: Subtitle updated to state the tool provides example hardware configurations only
  • Sizer: vCPU Ratio Manual Override: Users can now manually change the vCPU Overcommit Ratio without auto-scaling overriding their selection. Auto-escalation is locked when the user manually sets the ratio, and resets when workloads are added or removed
  • Sizer: AMD CPU Suggestion Tip: When Intel cores and sockets are maxed and compute utilization ≥80% (at baseline 4:1 ratio), a tip suggests AMD EPYC Turin as an alternative with higher core counts. Condition uses baseline 4:1 ratio so the tip persists even when auto-scaled to 5:1 or 6:1
  • Sizer: AMD EPYC Turin Core Options: Updated AMD 5th Gen EPYC Turin to include 144, 160, and 192 cores per socket (maxCores: 192), reflecting the full Turin product line
  • Sizer: Auto-Scaled Field Visual Indicators: Hardware fields that are auto-scaled now show a purple border glow animation and an "AUTO" badge on their labels, providing clear visual feedback on which settings were automatically adjusted
  • Sizer: Capacity Label Renames: "Capacity Breakdown" renamed to "Capacity Usage for Workload"; sub-labels now include "- Consumed" suffix for clarity
  • Sizer: Infrastructure_1 Volume Deduction: 256 GB usable capacity reserved by Storage Spaces Direct (Infrastructure_1 volume) is now deducted from overall usable storage in all capacity calculations, with a sizing note
  • Sizer: Disk Bay Consolidation: When auto-scaling would fill ≥50% of available disk bays, the sizer now evaluates larger disk sizes and selects fewer, larger disks to leave bays free for future expansion, with a sizing note explaining the optimisation
  • Sizer: Storage Limit Enforcement: Configurations exceeding 400 TB per machine or 4 PB per storage pool are now flagged with 🚫 errors, a red warning banner, and export/Configure in Designer are blocked until corrected
  • Sizer: Dead Code Cleanup: Removed unused dual parity option, dead functions, and consolidated resiliency constants
  • Sizer: Power Estimate Core Scaling: CPU TDP in the power estimate now scales with the selected core count (40% base + 60% proportional), so reducing cores visibly reduces estimated power
  • Sizer: Single Node Default Resiliency: Single-node clusters now default to Two-Way Mirror instead of Simple (No Fault Tolerance)
  • Sizer: Cluster Type & Nodes Label Styling: Bolder weight, larger font, and primary text colour for Cluster Type and Number of Physical Nodes labels
  • Sizer: Disk Consolidation Count Fix: Fixed consolidation only increasing disk count — now bidirectional; stale counts no longer persist after page refresh/resume
  • Sizer: Consolidation Note After Headroom: Fixed consolidation sizing note showing wrong disk count when headroom pass added extra disks
  • Sizer: HTML Validation Fix: Encoded raw & as &amp; in the sizer heading
  • Sizer: AUTO Badge Persistence Fix: Fixed AUTO badges disappearing from CPU Cores and Memory fields when adding workloads that scale nodes without changing per-node values

🎉 Version 0.15.x Series (February 2026)

0.15.98 - Default Gateway Field Fix for Safari
