Eight 3.5\" front bays for SAS or SATA spinning drives (or 3.5\" SAS SSDs in the rare case where 3.5\" flash makes sense), with no NVMe path: the LFF backplane is purpose-built for capacity-per-bay, not latency. The compute envelope underneath is the full R750xs platform, which is what separates this from a pure storage appliance: for converged nodes that run NAS plus deduplication and compression, or Ceph plus client workloads, the dual-socket-capable Ice Lake compute is meaningful.

The top-bin Platinum 8380 (40 cores) is not supported; that is reserved for the R750 flagship, and the 32-core ceiling is a genuine platform validation limit. On an LFF storage node, CPU is rarely the bottleneck.

Single-socket is the common pattern on a storage box; the second socket is available for converged compute but is not a standard field upgrade, so decide socket count at procurement.

For an LFF NAS or backup target, size memory to the workload: 128 to 256 GB for file-system cache on a straightforward NAS, 256 to 512 GB where dedup-aware backup software keeps a large in-memory hash table.

For a production LFF NAS, 25 GbE is the standard recommendation; 10 GbE is acceptable for smaller branch deployments, and 100 GbE is worth it only on high-concurrency or high-throughput backup targets.
