Source facts

\n

Storage Spaces Direct combines servers with internal storage into a clustered software-defined storage solution. Its overview describes pooling drives across physical servers and providing cache, tiers, and resiliency within that pool. The design uses Failover Clustering, Cluster Shared Volumes, SMB3, and Storage Spaces, together with the Software Storage Bus. Microsoft documentation.

\n

Applicability

\n

Use this review when documenting the architecture of a supported Storage Spaces Direct environment. Identify the servers, local drives, network paths, pool, and consuming workload. Review the current hardware and scale requirements separately from the conceptual diagram.

\n

DSE recommendation

\n

Create a component map that follows the workload to its volume, pool, server storage, and interserver network. Assign an owner for each layer and record where its health evidence is obtained. Use the map to organize incident information before changing settings. Keep architecture explanation separate from the installation procedure and from later decisions about volume size or resiliency.

\n

Verification

\n

Compare the map with the actual cluster, pool, and volume inventory. Trace one representative workload and verify that its documented path matches the deployment. Record discrepancies and update ownership before relying on the map during an outage. Use a separately approved failure exercise to assess availability; a component diagram alone is not an observed recovery result.
