This is a deliberately specialized configuration: 4-socket compute for scale-up workloads combined with 24-bay SFF storage for high-density database, analytics, or HCI data that lives locally rather than on a SAN.\u003c\/p\u003e\u003cp\u003eFor the full DL560 Gen10 platform documentation - including the honest framing on when 4-socket compute is and isn't the right call, Section 12 platform vocabulary (CPU\/memory\/PCIe\/management), and Dell PowerEdge R840 cross-vendor reference - see the \u003ca href=\"\/products\/server-design-lab-hpe-dl560-g10-8-bay-2-5-drives\"\u003eDL560 Gen10 8-Bay 2.5\"\u003c\/a\u003e canonical. This page focuses on what's specific to the 24-bay variant: when 24 SFF bays alongside 4-socket compute is the right tool, the bay-count-driven workload patterns, and the storage controller and power decisions that change at 24 bays.\u003c\/p\u003e\u003cp\u003eTo configure a build, call 1-800-778-1545 or use the quote form below. Every refurbished unit ships under our 180-day warranty with 12+ hour burn-in testing, and volume pricing starts at 5 units. The 24-bay configuration benefits from extra design discussion - 4-socket compute plus 24 SSDs in 2U is genuinely dense and the architectural choices have downstream operational consequences worth getting right at quote time.\u003c\/p\u003e\u003chr\u003e\u003ch2\u003eWhen 24 SFF Bays + 4-Socket Makes Sense\u003c\/h2\u003e\u003cp\u003eThe 24-Bay DL560 is a deliberately narrow configuration. Most 4-socket workloads (SAP HANA, Oracle Database, mission-critical virtualization, SQL Server Enterprise) don't need 24 local SFF drives - they either use a SAN for primary storage or a smaller number of high-performance local SSDs alongside networked storage. The DL360-class 8-Bay DL560 is the right answer for most of those builds.\u003c\/p\u003e\u003cp\u003eThe 24-Bay DL560 earns its place when both 4-socket compute AND high-density local SSD storage are genuine requirements. The specific scenarios:\u003c\/p\u003e\u003cul\u003e  \u003cli\u003e\n\u003cstrong\u003eSAP HANA with large local SSD persistence layer.\u003c\/strong\u003e HANA in-memory databases benefit from local NVMe\/SSD for log persistence and warm-data tiering rather than depending on SAN latency for log writes. 24 SFF bays alongside HANA-scale memory (3-6 TB DDR4 + up to 12 TB Persistent Memory on L-series CPUs) enables a complete in-memory plus fast-persistence architecture in a single chassis. The persistence layer fits in the chassis instead of crossing the SAN, which matters for HANA savepoint and log-replay latency.\u003c\/li\u003e  \u003cli\u003e\n\u003cstrong\u003eOracle Database with local ASM diskgroups.\u003c\/strong\u003e Oracle RAC or large-instance Oracle databases where the design choice is local SSD storage rather than SAN. 24 SAS SSDs in ASM disk groups deliver high IOPS and predictable latency without the SAN dependency. Common when SAN is unavailable, undesirable for licensing\/cost reasons, or simply when the database team has decided ASM-on-local-SSD is the operational pattern they want to standardize on.\u003c\/li\u003e  \u003cli\u003e\n\u003cstrong\u003eSQL Server Enterprise with extensive tempdb and log staging on local SSDs.\u003c\/strong\u003e Per-core SQL Server licensing economics already favor consolidation on 4-socket compute; pairing with 24 high-endurance SSDs lets the entire tempdb plus transaction log infrastructure live on local NVMe\/SAS rather than crossing the SAN. Datafile-on-SAN plus tempdb-and-logs-on-local-SSD is a documented Microsoft pattern for performance-sensitive SQL Server deployments.\u003c\/li\u003e  \u003cli\u003e\n\u003cstrong\u003eHigh-density VMware HCI or vSAN ReadyNode at 4-socket scale.\u003c\/strong\u003e vSAN ReadyNode configurations at 24 SFF bays with 4-socket compute deliver high VM density per host. Fewer, larger HCI nodes reduce vSphere license count (which is per-CPU socket) and rack footprint. The 24-bay DL560 is at the high end of the vSAN ReadyNode footprint and works well when the goal is consolidating to the fewest hosts possible.\u003c\/li\u003e  \u003cli\u003e\n\u003cstrong\u003eIn-memory analytics with large local hot-data tier.\u003c\/strong\u003e Analytics workloads (Splunk, Elasticsearch hot-tier, in-memory data grids) that need both maximum processing capacity (4-socket) and large local SSD datasets that don't fit entirely in DRAM but are too latency-sensitive for SAN. 24 SAS SSDs as a tiered hot-data layer behind in-memory analytics is a meaningful configuration.\u003c\/li\u003e  \u003cli\u003e\n\u003cstrong\u003eMicrosoft Storage Spaces Direct (S2D) at 4-socket scale.\u003c\/strong\u003e S2D requires HBA-mode storage and benefits from high drive counts per node for performance scaling. 24 NVMe or SAS SSDs in a 4-socket S2D node delivers a high-density HCI design with the per-node compute headroom to host many workloads.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eIf either the 4-socket compute or the 24-bay storage capacity is more than the workload actually needs, a different platform delivers better economics. The DL380 Gen10 24-Bay covers high-density storage at the dual-socket tier; the DL560 Gen10 8-Bay covers 4-socket compute with modest local storage. Pay for both 4-socket and 24-bay only when both are genuine requirements.\u003c\/p\u003e\u003chr\u003e\u003ch2\u003eStorage - 24 SFF Bays\u003c\/h2\u003e\u003cp\u003eTwenty-four 2.5\" SAS\/SATA\/NVMe hot-swap bays across three drive boxes (Box 1, Box 2, Box 3) in the front of the chassis. With the full 24-bay configuration populated, the optional Universal Media Bay (front display port plus optical drive) is not supported - the media bay occupies the same physical position as one of the drive boxes. Production 24-bay builds typically don't need the media bay; remote iLO 5 access covers the operational requirements that the media bay served on earlier platforms.\u003c\/p\u003e\u003cp\u003eDrive options span the full Gen10 SFF portfolio: SAS SSDs (mixed-use and read-intensive endurance tiers, 480 GB through 7.68 TB), SATA SSDs for cost-optimized roles, SAS HDDs at 10K and 15K for moderate-IOPS data, NVMe SSDs via specific drive cage and riser combinations (see NVMe section below), and self-encrypting drive variants for compliance-regulated deployments. Per-drive type mixing is supported subject to controller capability.\u003c\/p\u003e\u003cp\u003eRAID guidance at 24 SFF bays: RAID 6 is appropriate for capacity-optimized SAS\/SATA SSD pools where rebuild windows on individual drive failure need to be tolerated; RAID 10 is appropriate for write-intensive workloads where the 50% capacity overhead is acceptable in exchange for write performance and shorter rebuild windows; RAID 50 or RAID 60 across multiple sub-pools (e.g. 2x RAID 6 of 12 drives, striped) balances rebuild scope against usable capacity. We discuss RAID layout in every 24-Bay quote.\u003c\/p\u003e\u003ch3\u003eBoot Drives\u003c\/h3\u003e\u003cp\u003eM.2 boot via the HPE M.2 SSD enablement option is strongly recommended at 24 bays - consuming 2 bays for OS boot mirroring wastes meaningful storage capacity in a configuration that exists specifically for high-density local SSD. M.2 boot mounts in a PCIe slot or on the CPU mezzanine board and frees all 24 SFF bays for data. Standard on our 24-Bay DL560 quotes unless customer specifies otherwise.\u003c\/p\u003e\u003chr\u003e\u003ch2\u003eStorage Controllers at 24-Bay Scale\u003c\/h2\u003e\u003cp\u003eAt 24 SFF bays, the storage controller decision matters more than at 8 bays - controller capability, RAID overhead, and write-cache sizing become primary design factors rather than secondary considerations:\u003c\/p\u003e\u003cul\u003e  \u003cli\u003e\n\u003cstrong\u003eSmart Array P816i-a SR Gen10 (4 GB FBWC).\u003c\/strong\u003e The standard production controller for the 24-Bay configuration. 4 GB flash-backed write cache absorbs burst writes across the larger drive pool, tri-mode SAS\/SATA\/NVMe support handles mixed drive types.

At 24 bays the battery is essentially mandatory - write workload at this drive count makes write-cache protection a hard requirement. We include the battery on every 24-Bay quote with a P-series controller. On P824i-p MR builds, confirm CacheCade SSD requirements at quote time - the MR controller's value depends on the CacheCade SSD configuration matching the workload's read\/write profile.\u003c\/p\u003e\u003chr\u003e\u003ch2\u003eNVMe at 24 Bays\u003c\/h2\u003e\u003cp\u003eThe DL560 Gen10 supports up to 12 NVMe SSDs (half of the 24-bay backplane) with the right combination of NVMe drive cages, PCIe risers, and Smart Array controllers. NVMe at this drive count requires PCIe lane budget that competes with other expansion (the 4-port NVMe Mezzanine card on the CPU mezzanine board doesn't consume PCIe slots but is limited to 8 NVMe drives; beyond that requires PCIe slot consumption).\u003c\/p\u003e\u003cp\u003eCommon NVMe configurations on the 24-Bay DL560:\u003c\/p\u003e\u003cul\u003e  \u003cli\u003e\n\u003cstrong\u003e8 NVMe + 16 SAS\/SATA SFF.\u003c\/strong\u003e NVMe via the mezzanine card (no PCIe slot consumption), remaining 16 bays via SAS\/SATA on a P816i-a or HBA.

With 4x Platinum 8280 at 205W each (820W CPU alone) and 24 NVMe SSDs, the draw rises to approximately 1,800-2,000W sustained.\u003c\/p\u003e\u003cp\u003eAt this power envelope, 1600W Titanium PSUs are mandatory and 4-PSU configurations are typically required for production HA. Recall from the canonical that 4x 1600W PSUs and the tertiary PCIe riser are mutually exclusive - on the 24-Bay configuration, 4-PSU is typically the right choice (high TDP plus production HA) and the platform delivers 6 PCIe slots maximum rather than 8.\u003c\/p\u003e\u003cp\u003e1600W Flex Slot Titanium PSUs require high-line input (200-240VAC) - confirm rack PDU and circuit capacity before deployment.
