It pairs four 3.5\" hot-swap bays with the same 4th and 5th Gen Intel Xeon Scalable socket, DDR5 memory, and PCIe Gen5 expansion as the rest of the R660xs family. This is the chassis to reach for when you want current-generation dual-socket compute alongside capacity-tier storage on a single node: backup targets, file servers, log aggregation, archive tiers, and edge sites where 3.5\" drives are the most cost-effective dollar-per-terabyte option.\u003c\/p\u003e\n\u003cp\u003eAs a 16th-gen platform, this server is offered New and Surplus New. Surplus New means a genuinely unused unit from excess inventory: never previously deployed, but sourced outside Dell's standard new-sales channel, which is why it prices below Dell-direct new. The same Wholesale Servers warranty coverage applies to both conditions. This page covers what is specific to the LFF chassis: 3.5\" capacity-drive support, the SAS\/SATA-only front backplane, and when LFF is the right answer against the 2.5\" SFF companions.

The 2.5\" SFF companions (the 8-Bay and 10-Bay) win on drive count and native NVMe, but a 3.5\" nearline SAS drive remains the cheapest way to buy bulk capacity, and four of them in a 1U chassis is the densest LFF layout Dell offers in this generation.\u003c\/p\u003e\n\u003cp\u003ePick this chassis when the workload is capacity-led rather than IOPS-led, and when keeping the storage on the same node as the compute matters: a backup repository that also runs the backup software, a file server, a SIEM data tier, or an edge node where local 3.5\" drives are easy to source. If the workload is flash-led, IOPS-bound, or needs more than four spindles, the decision points elsewhere, and the sections below say where.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eStorage: 4 3.5\" LFF Bays\u003c\/h2\u003e\n\u003cp\u003eFour 3.5\" hot-swap bays on the front, supporting SAS and SATA hard drives and SSDs. At 24 TB per drive, that is up to 96 TB raw per node; with RAID 6 across all four, roughly 36-48 TB usable depending on drive size. An optional rear 2x 2.5\" drive kit adds a small fast tier, and those rear bays can be NVMe if you want flash alongside the LFF capacity.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e3.5\" SAS HDD:\u003c\/strong\u003e the dollar-per-terabyte workhorse for capacity tiers.

NVMe on this chassis is available only through the optional rear 2x 2.5\" drive kit, which costs one PCIe slot.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoot: BOSS-N1 (cold-swap):\u003c\/strong\u003e the same boot subsystem as the rest of the R660xs family. Two M.2 NVMe SSDs in hardware RAID 1 on a dedicated card, keeping the OS off the four front bays so all of them stay available for data. The N1 is NVMe and cold-swap on the xs, not the hot-swap rear module of the larger R660.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch2\u003eStorage Controllers for LFF Capacity Tiers\u003c\/h2\u003e\n\u003cp\u003eThe controller lineup is the full R660xs family set (PERC H965i, H755, H755N, H355, the HBA355i pass-through adapter, and S160 software RAID), but the workload pattern on LFF capacity arrays narrows the sensible picks:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePERC H965i or H755 with battery-backed cache:\u003c\/strong\u003e the right pick for LFF parity arrays. Write coalescing through cache matters on spinning disk, where seek latency dominates write IOPS. Both support RAID 5, 6, 10, 50, and 60.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRAID 6 for large-capacity arrays:\u003c\/strong\u003e on any SAS array at 8 TB drives and up, double parity is the floor. Single-parity RAID 5 carries unacceptable rebuild risk at modern drive sizes; a second drive failure during a 12-36 hour rebuild window on a 4-disk array is a real exposure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePERC H355:\u003c\/strong\u003e a parity-free controller. The H355 supports RAID 0, 1, and 10 only, not RAID 5 or 6, so it is not the controller for a parity capacity array. Use the H755 or H965i where parity is required.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHBA355i pass-through:\u003c\/strong\u003e the right call when redundancy is handled in software (ZFS, Ceph, or backup-target software that manages its own resilience). Pass-through hands the raw drives to the OS with no RAID layer.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch2\u003eProcessors\u003c\/h2\u003e\n\u003cp\u003eThe R660xs takes up to two Intel Xeon Scalable processors in Socket E1 (LGA 4677) on the Intel C741 chipset. Both 4th Gen (Sapphire Rapids, 2023) and 5th Gen (Emerald Rapids, 2024) are supported in the same socket, so the generation choice is a price-and-availability decision rather than a board change. The xs is cost-optimized, so its practical CPU TDP ceiling lands around 225W (confirm the exact ceiling per SKU); the higher-TDP top-bin parts that the full R660 accepts are out of scope here.\u003c\/p\u003e\n\u003cp\u003eFor LFF capacity-tier builds, the CPU is rarely the bottleneck. A Silver 4410Y (12-core, 150W) or Silver 4416+ (20-core, 165W) is usually plenty for a backup target or file server. Spending on Gold-tier parts for a capacity node is seldom justified; if a build genuinely needs both heavy compute and LFF storage on one node, that is usually a signal the storage should move to SFF NVMe with a separate capacity tier. Top-bin CPUs require the high-performance heatsink, and a common field error is ordering a high-TDP CPU against the standard heatsink. A second common trap is the single-socket build: populating one socket halves the available memory channels and PCIe lanes, so size the socket count to the memory and expansion the workload actually needs.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eMemory\u003c\/h2\u003e\n\u003cp\u003eThe xs carries 16 DDR5 RDIMM slots, eight per CPU, wired as eight channels per CPU at one DIMM per channel. That channel count is the correct figure for Sapphire and Emerald Rapids; copy that claims twelve channels per CPU is wrong for this platform. The xs uses half the 32-slot topology of the full R660, which is the central cost-optimization tradeoff and the reason the memory ceiling is lower.\u003c\/p\u003e\n\u003cp\u003eSpeeds run at DDR5-4800 on 4th Gen parts and up to DDR5-5200 to 5600 on 5th Gen parts at one DIMM per channel. The platform is RDIMM only; there is no LRDIMM or persistent-memory path on the xs. Maximum capacity is roughly 1.5 TB using 96 GB RDIMMs across all 16 slots (confirm the ceiling per SKU and DIMM availability). For LFF capacity workloads, 256 GB to 512 GB is the common population; backup and file-serving tiers rarely need the full ceiling, and the budget is better spent on drives.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eNetworking and PCIe Expansion\u003c\/h2\u003e\n\u003cp\u003eNetworking is OCP NIC 3.0, the current Dell modular standard, not the older rack Network Daughter Card of earlier generations. The base configuration provides dual 1 GbE LOM, with 10, 25, or 100 GbE available through the OCP 3.0 slot, plus an optional add-in LOM card. For a capacity node, dual 10 or 25 GbE is the typical pick: enough to move bulk data without overspending on 100 GbE that spinning disk cannot saturate.\u003c\/p\u003e\n\u003cp\u003ePCIe expansion is configuration-dependent on this 1U chassis: typically two PCIe Gen5 slots or three Gen4 slots, alongside the OCP slot and a dedicated slot for the PERC controller. The most important tradeoff to plan for on the LFF chassis is the optional rear 2x 2.5\" drive kit, which consumes one of those PCIe slots. If you want both rear NVMe and a high-speed NIC, account for the slot budget up front rather than discovering the conflict at rack time.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eGPU Support\u003c\/h2\u003e\n\u003cp\u003eThe R660xs is not a GPU platform. The cost-optimized 1U chassis does not provide the slot width, power delivery, or thermal envelope for accelerators, and the LFF variant in particular spends its limited expansion budget on storage and networking. If the workload needs GPU compute, the full \u003ca href=\"\/products\/dell-poweredge-r660-10-bay-build-your-own\"\u003eR660 (1U)\u003c\/a\u003e supports up to three single-wide cards, and the 2U R760 supports double-wide accelerators. For LFF capacity plus accelerators on one node, a 2U platform is the right starting point. Do not plan GPU work around this chassis.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eManagement: iDRAC9 Generation\u003c\/h2\u003e\n\u003cp\u003eThe R660xs ships with iDRAC9, the 16th-generation Dell management controller, with the Lifecycle Controller for agent-free firmware and configuration management. Note that 16th-gen hardware uses iDRAC9; iDRAC10 is the 17th-generation controller and does not apply here. iDRAC9 Enterprise is the recommended license tier for remote KVM, virtual media, and automated deployment.\u003c\/p\u003e\n\u003cp\u003eThe security baseline is the full 16th-gen stack: Silicon Root of Trust anchoring the firmware verification chain, Secure Boot, System Lockdown, multi-factor authentication, and TPM 2.0.
