Screen guide ​

What each screen answers, what it needs, and what it does not claim. Every screen plans against Azure Local 12.2609 (latest); the Microsoft Learn facts behind the rules are listed on the in-app References page with the date each was last checked.

Fit and Recommendations ​

Question: does my combined workload demand fit this hardware, and how many same-spec nodes would it take?

  • Inputs: hardware, every enabled workload source (individual VM inventory, quick VM groups, specialized services), the volume layout, and the maintenance reserve (none, N+1, N+2).
  • Reads: vCPU, memory and storage-pool footprint against what the hardware provides, and a node-count comparison for 1 to 16 nodes (2, 4, 6 and 8 for rack aware).
  • N+1 and N+2 are planning choices, not platform limits. N+1 keeps compute for the largest single failure (one node down). N+2 covers one node in maintenance while another fails. They reduce CPU and memory only; storage keeps the per-drive rebuild reserve instead.
  • Single node: the page reports that N+1 cannot be met and why.
  • Rack aware: also shows whether the surviving zone can run the full demand if one rack fails.
  • Not claimed: per-VM placement, storage performance, networking or hardware support. A VM larger than one host is reported separately because more nodes cannot fix it.
  • Built vs sized (linked from the page) compares the same demand with hardware that was actually built. See As-built comparison.

Recommendations (Hardware options) ​

Question: which reviewed OEM planning configurations could carry this demand?

  • Inputs: minimum and maximum node count (1 to 16), additional headroom percentage, optional vendor filter.
  • Reads: each reviewed preset is evaluated with the same fit engine. A preset is listed only when CPU, memory and storage footprint meet the demand plus your headroom.
  • Sorting: fewest nodes, then cores, memory and raw storage. It is not a price ranking.
  • Not claimed: presets are editable examples with a source and review date, not certified bills of materials. Confirm in the Azure Local catalog. A preset with cache drives is never offered for a single node because the cache is unsupported there.

Thin provisioning ​

Question: what are the risks of thin volumes on Azure Local, and how do I monitor them?

  • A reference page: pool exhaustion behaviour, monitoring commands and a deployment checklist. It does not change your numbers.
  • In the planner, thin volumes are still checked at full planned consumption for fit, because over-committing removes the free space that repair needs.

References ​

Question: where does each rule come from?

  • Platform facts table: every Azure Local rule the engine encodes, its Microsoft Learn link and the date it was verified.
  • Planning assumptions list: defaults Surveyor chose that are not Microsoft requirements (8 GB host memory reserve, 4 host vCPUs, oversubscription ratio, N+1/N+2, 1% pool metadata, infrastructure volume size, the all-flash cache-ratio guidance).
  • Then the catalogue of Learn pages for storage, compute, AVD, AKS and backup planning.

About ​

  • The version, release history and what is included. The sidebar badge and every report show the planning basis, Azure Local 12.2609 (latest).

Projects (Open and Compare) ​

  • Download project saves the active area (storage or workload) as a .surveyor.json file; Open or compare previews a file against the current plan before restoring it. Plan manifests from Export JSON also open here.
  • Files are described by JSON Schemas. Browser storage is not a backup; see privacy and data.
