Up to 160 TB raw at 8 x 20 TB NL-SAS, with 15th gen platform currency at value-tier 2U economics. This is the R750xs configuration for smaller-scale capacity workloads: branch-office NAS, modest backup targets, departmental file servers, and entry-tier Ceph capacity nodes, where the 12-Bay R750xs LFF is more capacity than the deployment needs.\u003c\/p\u003e\u003cp\u003eThis page covers what changes at the 8-bay LFF chassis. The shared platform detail (the dual-socket-capable Ice Lake architecture, 16 DIMM slots, PCIe Gen4 expansion, and the R750xs versus R750 envelope comparison) is documented on the canonical \u003ca href=\"\/products\/dell-poweredge-r750xs-8-bay-2-5-build-your-own-server\"\u003eR750xs 8-Bay 2.5\" page\u003c\/a\u003e. As a 15th gen platform the R750xs is no longer sold factory-new by Dell; Wholesale Servers stocks it refurbished and fully tested, as the cost-correct alternative to the R540 LFF predecessor or to stepping up to the R750 flagship.\u003c\/p\u003e\u003cp\u003eTo spec an R750xs LFF build, call 1-800-778-1545 or use the quote form on this page; we respond within 24 hours.

It exists for the deployment where eight large drives cover the requirement and twelve would be over-provisioned. 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. Where eight LFF bays is too few, the \u003ca href=\"\/products\/dell-poweredge-r750xs-12-bay-3-5-build-your-own-server\"\u003e12-Bay 3.5\"\u003c\/a\u003e is the next rung; where 1U density matters more than bay count, the \u003ca href=\"\/products\/poweredge-r650xs-4-bay-3-5-build-your-own\"\u003eR650xs 4-Bay 3.5\"\u003c\/a\u003e is the companion platform.\u003c\/p\u003e\u003chr\u003e\u003ch2\u003eStorage - 8 LFF Bays\u003c\/h2\u003e\u003cp\u003eEight 3.5\" SAS\/SATA hot-swap front bays.

Excellent sequential throughput, modest random IOPS.

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. A single Silver 4310 or 4314 covers a straightforward NAS or archive target; step to a Gold 5318Y or 6338N when the node also runs dedup, compression, or erasure coding, which are CPU-bound. 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. Both sockets must carry matching CPUs.\u003c\/p\u003e\u003chr\u003e\u003ch2\u003eMemory\u003c\/h2\u003e\u003cp\u003e16 DDR4 DIMM slots: 8 per CPU, one DIMM per channel, 8 channels per socket, registered ECC only, DDR4-3200. Maximum is 1 TB with 16 x 64 GB RDIMM, and there is no Optane PMem support (that is an R750 flagship feature). 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. The 1 DPC topology means there is no second-DIMM-per-channel expansion path later, so populate to the target at procurement.\u003c\/p\u003e\u003chr\u003e\u003ch2\u003eNetworking and PCIe Expansion\u003c\/h2\u003e\u003cp\u003eThe R750xs uses OCP NIC 3.0, the 15th gen shift away from the rNDC mezzanine of the 13th and 14th gen platforms. One OCP 3.0 slot plus the PCIe Gen4 expansion slots. 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. Eight spinning drives will not saturate 100 GbE on their own.\u003c\/p\u003e\u003cp\u003ePCIe expansion is up to 6 slots (5 Gen4 plus 1 Gen3), all low-profile. On this chassis the budget is rarely tight: a 25 GbE OCP, the RAID controller, and the BOSS-S1 card leave headroom. Place any Gen4 adapter so it avoids the single Gen3 slot.\u003c\/p\u003e\u003chr\u003e\u003ch2\u003eGPU Support\u003c\/h2\u003e\u003cp\u003eThis is not a GPU platform, and an LFF capacity chassis is the last place to put one. The value-tier power and PCIe budget supports at most a single-width 75W card (an NVIDIA A2 or L4) for incidental transcode, but there is no thermal or slot headroom for compute GPUs, and a storage node rarely wants one. For GPU compute, the R750 or the purpose-built R750xa is the right platform.\u003c\/p\u003e\u003chr\u003e\u003ch2\u003eManagement - iDRAC9 Generation\u003c\/h2\u003e\u003cp\u003eiDRAC9 Enterprise is the production recommendation, the same enhanced 15th gen iDRAC9 used across the R650 and R750: Active Health System, Secured Component Verification, iDRAC Direct via front-panel micro-USB, and Quick Sync 2.0. A hardware Silicon Root of Trust validates firmware at boot, with Secure Boot, signed firmware updates, and System Lockdown on the Enterprise and Datacenter tiers. TPM 2.0 is standard, and the Lifecycle Controller handles agent-free deployment and firmware management. For a storage node that often runs lights-out, the iDRAC9 remote console and drive-health telemetry are the day-to-day operational surface.\u003c\/p\u003e\u003chr\u003e\u003ch2\u003ePower and Cooling\u003c\/h2\u003e\u003cp\u003eThe 8-bay LFF configuration draws less peak power than the SFF SSD variants, because spinning HDDs are lower power per drive than SAS SSDs at sustained load and the 8-bay count keeps aggregate drive power modest.
