The refurbished HPE ProLiant DL380 Gen9 8-Bay 2.5" is the compute-focused member of the DL380 Gen9 family - the eight-bay variant of HPE's Gen9 dual-socket 2U mainstream platform, with eight 2.5" SFF hot-swap bays in the standard chassis. It runs the same Intel Xeon E5-2600 v3 (Haswell-EP) or v4 (Broadwell-EP) processors on the Grantley platform with the C610 chipset, the same 24 DDR4 DIMM slots and 3 TB memory ceiling, the same modular Smart Array storage controllers, the same FlexibleLOM networking, and the same iLO 4 management as the rest of the Gen9 line. What is different is the storage footprint: eight bays is the sweet spot for compute-driven workloads where primary data lives on SAN, NFS, or a distributed file system and local storage handles the OS, application binaries, and modest hot-data staging.

Within the family, the sixteen-bay configuration is the mainstream SFF default; this eight-bay build is for deployments that do not need that much local storage and would rather not pay for bays that sit empty. For family-level positioning and the cross-vendor comparison, the DL380 Gen9 16-Bay 2.5" is the primary page. This page carries the full platform detail in its own right and focuses on what is specific to the eight-bay variant: when eight SFF bays is the right tool, the bay-count-driven workload patterns, and the storage decisions that change at eight versus sixteen or twenty-four.

When 8 SFF Bays Is the Right Default

The 8-Bay DL380 Gen9 fits most production dual-socket Gen9 workloads where storage is networked rather than local. The bay-count decision framework:

• VM cluster nodes with SAN-backed datastores. Boot plus a small local cache or VM tier lives on the eight bays; primary datastores sit on shared FC or iSCSI SAN reached through an FC HBA in PCIe expansion.
• Application servers with modest local data. The OS plus four to six SSDs for application data, logs, or staging, with the database backend on the network. Web, app, and middleware tiers where local storage is supplementary.
• Mid-tier SQL Server or Oracle hosts with networked primary storage. Local SSDs cover the OS, tempdb or Oracle Grid binaries, and transaction logs while the datafiles live on SAN.
• Domain controllers, file servers, and infrastructure services. Modest local capacity is sufficient, delivered at materially lower acquisition cost than the 16- or 24-bay builds.
• Branch office and ROBO deployments. Dual-socket compute with modest local storage for branch file services, AD/DNS, and application hosting; eight bays matches the typical ROBO footprint.
• Lab, dev, and staging environments. Mirroring Gen9 production at lower per-node cost, where eight bays is sufficient for non-production patterns.

If the workload genuinely needs more than eight bays of local storage (VDI hosts, HCI nodes, database hosts with local primary storage, mid-size file servers), step to the DL380 Gen9 16-Bay 2.5" for the SFF sweet spot or the DL380 Gen9 24-Bay 2.5" for maximum SFF density. If eight is sufficient, the 8-Bay delivers the same Gen9 platform at meaningful cost savings.

Storage - 8 SFF Bays

Eight 2.5" SAS/SATA hot-swap bays in the standard chassis configuration (Box 1 populated). The DL380 Gen9 chassis is upgradeable to 16, 18, or 24 SFF in the field via additional drive-cage kits (Box 2 and Box 3 plus the appropriate backplane), but the eight-bay starting point is the right answer when the workload does not anticipate needing more local storage. The optional Universal Media Bay (PN 724865-B21) is available on the eight-bay chassis and provides front VGA, 2x USB 2.0, and optional 2 SFF rear bays plus optical-drive support - useful for deployments that need front-panel management ports.

Drive options span the full Gen9 SFF portfolio: SAS SSDs in mixed-use and read-intensive endurance tiers (200 GB through 3.84 TB at Gen9 launch, larger capacities on later firmware), SATA SSDs for cost-optimized OS and bulk-storage roles, 10K and 15K SAS HDDs for moderate-IOPS data (300 GB through 2.4 TB at SFF), self-encrypting drive variants for compliance, and NVMe SSDs via the Express Bay option in Box 1 (consuming bay count for NVMe positions).

Common DL380 Gen9 8-Bay storage profiles:

• VMware cluster node, SAN datastore primary. 2x SSDs RAID 1 ESXi boot, six bays for a vSAN cache tier or local-VM datastore. Primary VM storage on shared FC/iSCSI SAN.
• Hyper-V cluster node with CSV cache. 2x SSDs for Windows Server, six SSDs for a CSV cache tier. Primary VM storage on SOFS or SAN.
• Application server with local logs/staging. 2x SSDs RAID 1 OS, 4-6 SSDs in RAID 5/10 for app data and logs. Primary data backend on a networked database.
• SQL Server with networked datafiles. 2x SSDs OS, 2x SSDs tempdb mirror, 4x SSDs log files in RAID 10. Primary database files on a SAN datastore.
• Domain controller / infrastructure services. 2x SSDs RAID 1 for OS and AD/DNS/DHCP roles, the remaining bays for supplementary storage or left unused.
• Branch office multi-role server. 2x SSDs OS, six SAS HDDs in RAID 6 for branch file shares. Cost-optimized branch deployment with single-server compute and storage.

Boot Drives

On the eight-bay configuration, boot-drive placement matters more than on 16- or 24-bay builds because consuming two of eight bays for the OS is a meaningful 25% of the storage budget. Three options:

• Rear-bay 2 SFF kit. Preserves all eight front bays for data; the OS lives in the rear bays. The right pattern when front-bay capacity matters.
• M.2 SATA SSDs via the HPE M.2 enablement card. M.2 boot in a PCIe slot, freeing all front bays for data. Consumes a PCIe slot but preserves the storage budget.
• 2x front-bay SSDs in RAID 1. The simplest configuration; consumes two of eight front bays. Acceptable when the six remaining bays cover the workload's data requirement.

We default to the rear-bay 2 SFF kit on 8-Bay DL380 Gen9 quotes when front-bay capacity is at all constrained, and to the standard front-bay RAID 1 pattern when the workload comfortably fits in six bays of data.

Storage Controllers

The controller decision does not change with bay count - only the cache-sizing tradeoff does. The same modular Smart Array "ar" controllers used across the family apply here:

• Smart Array P440ar (2 GB FBWC). The mainstream production controller for the eight-bay build. 2 GB of flash-backed write cache is comfortably sized for eight SSDs under most workload patterns, and it is the right pick for traditional hardware RAID in production.
• Smart Array H241 (HBA mode, PCIe plug-in). For software-defined storage (vSAN, S2D, Ceph, ZFS). Clean SAS pass-through with no hardware RAID.
• Smart Array P840ar (4 GB FBWC). The premium controller. Rarely needed at eight bays - the P440ar's 2 GB cache is sufficient for this storage scale.
• Dynamic Smart Array B140i (embedded software RAID). Acceptable for OS boot mirroring only; not appropriate for production data.

The HPE Smart Storage Battery is required with any P-series controller. The Gen9 FBWC battery is a wear item with a documented 5-7 year service life; we disclose battery state on every quote and replace cache modules that are past spec as part of build prep.

Processors

1 or 2 sockets of Intel Xeon E5-2600 v3 (Haswell-EP) or v4 (Broadwell-EP) on the C610 Grantley chipset. Mixing v3 and v4 is not supported - all installed CPUs must be the same generation, though a field upgrade from v3 to v4 (replacing both at once) is supported. Single-socket builds cut DIMM slots in half (12 instead of 24) and PCIe to three slots, so 2-socket is the production standard. The eight-bay chassis shares the same 2U thermal envelope as the higher-bay variants, and its lower drive count leaves a little more power and airflow headroom for top-bin CPUs.

• E5-2680 v4 (14 cores, 120W, DDR4-2400). The Gen9 production mainstream - 28 cores at 2S, balanced TDP, standard heatsink.
• E5-2690 v4 (14 cores, 135W, 2.6 GHz). Higher base frequency for single-thread-sensitive workloads within the same core budget.
• E5-2699 v4 (22 cores, 145W). Top-bin Broadwell-EP - 44 cores at 2S, the platform maximum. Requires the high-performance heatsink (auto-included for 120W+ CPUs).
• E5-2650 v4 (12 cores, 105W). Mid-tier production at modest TDP and lower acquisition cost - a good fit for general virtualization and application servers.
• E5-2620 v4 (8 cores, 85W) and E5-2667 v4 (8 cores, 135W, 3.2 GHz). Entry-tier and high-frequency specialty SKUs; the 2667 v4 is the per-core-licensing pick for Oracle and SQL Server Enterprise. Haswell-EP v3 equivalents are available at lower cost with a DDR4-2133 cap.

Memory

24 DDR4 DIMM slots (12 per CPU; only 12 are available with a single CPU). RDIMM and LRDIMM are supported but cannot be mixed in one server; the maximum is 3 TB with 128 GB LRDIMMs across all 24 slots on v4 CPUs. HPE DDR4 Smart Memory is required for rated speeds - third-party DDR4 drops to lower speeds, documented HPE behavior across Gen9.

Memory speed depends on CPU generation and population: v3 caps at DDR4-2133, v4 at DDR4-2400, and full 24-DIMM population drops to DDR4-1866 or DDR4-1600 depending on rank. For maximum bandwidth, populate at 1 DPC (12 DIMMs at 2S). HPE Persistent Memory (NVDIMM-N, 8 GB and 16 GB) is supported on v4 CPUs for DRAM-class latency with battery-backed persistence - uncommon, but available for SQL Server transaction logs and in-memory database WAL.

Networking and PCIe Expansion

The embedded HPE 4-port 1 GbE 331i adapter is standard and consumes no slot. The optional FlexibleLOM mezzanine supports 10 GbE SFP+ (530FLR/534FLR), 10 GBASE-T, 25 GbE SFP28, and converged FlexFabric. Unlike the DL580 Gen9, Wake-on-LAN works on both the embedded 1 GbE and the FlexibleLOM here. PCIe expansion is three PCIe Gen3 slots with one CPU, expanding to six with both CPUs populated; the +3-slot secondary riser requires the second processor. All slots are PCIe Gen3 and accept cards up to 150W, higher with the supplemental power-cable kit. On a SAN-backed eight-bay build, an FC HBA or a 10/25 GbE FlexibleLOM is usually the first expansion priority.

GPU Support

GPU and accelerator support is bounded by the PCIe Gen3 generation and the 2U thermal envelope. The eight-bay build's lower drive count can leave a little more PSU headroom for accelerators, but the slot and thermal limits are the same as the rest of the family:

• Single-width accelerators. Cards like the NVIDIA Tesla T4 (70W, single-slot, passive) for inference, transcoding, or VDI graphics offload. They fit standard riser positions and need no GPU power-cable kit.
• Double-width GPUs. Passively cooled Gen9-era cards (NVIDIA M40, M60, K80-class). These require the high-performance heatsink and an additional GPU power-cable kit (PN 669777-B21); plan for up to two, subject to PSU sizing.
• Thermal envelope. GPU builds require performance heatsinks and the high-performance fan kit, and ASHRAE A3/A4 ambient headroom is reduced with double-wide cards. We validate inlet temperature against the configuration at quote time.
• FPGA and specialty cards. The PCIe Gen3 x16 slots accept FPGA and specialty cards within the 150W per-slot limit. PCIe Gen3 bandwidth is the ceiling - workloads needing PCIe Gen4 GPU bandwidth belong on Gen10 Plus or Gen11.

Management - iLO 4 Generation

The DL380 Gen9 ships with HPE iLO 4: remote console (an iLO Advanced license enables full graphical KVM), virtual media, IPMI, SNMP telemetry, Active Health System logging, and HPE OneView compatibility - the same iLO 4 generation across the Gen9 line, which is part of the platform's operational-standardization value. The key difference from Gen10 is that iLO 4 has no Silicon Root of Trust; the hardware-anchored firmware-verification chain arrived with iLO 5 on Gen10. UEFI Secure Boot is supported and is the right pattern for production Gen9 builds, with compensating controls where a compliance framework requires firmware-integrity attestation. iLO Advanced is typically a separate cost and is rarely optional for production data-center deployments; we quote it explicitly.

Power and Cooling

The same HPE Flex Slot power supplies as the rest of the DL380 Gen9 family - 500W, 800W, or 1400W Platinum/Titanium in 1+1 redundant configurations, plus the optional HPE Flexible Slot Battery Backup module. The eight-bay configuration's lower drive count means lower total power draw than the 16- or 24-bay variants: 500W PSUs are adequate for many eight-bay builds, and 800W in 1+1 covers all common dual-socket configurations including E5-2680/2690 v4 with full memory.

For high-TDP CPUs (E5-2699 v4 at 145W, E5-2667 v4 at 135W) or builds with double-wide GPUs, 1400W PSUs are required. We run the HPE Power Advisor against every DL380 Gen9 quote to validate PSU sizing. Thermal: ASHRAE A3 (40 C) and A4 (45 C) extended-ambient operation is supported with the performance heatsinks (auto-included for 120W+ CPUs).

Physical Specs & Platform Notes

• Form factor: 2U rackmount, standard-depth Gen9 enclosure shared across the DL380 Gen9 bay-count variants; with the cable management arm installed, plan for additional rear clearance.
• PCIe expansion: up to six PCIe Gen3 slots with both CPUs populated (three with one CPU), split full-height and low-profile across the primary and secondary risers; the secondary riser requires the second processor.
• Parts availability: excellent. The DL380 Gen9 shipped in one of the largest install bases of any 2U generation, so drives, PSUs, risers, heatsinks, FlexibleLOM cards, and Smart Array controllers are widely available, and third-party maintenance spares depth is strong in major metros.
• Accessories we recommend: the 2U SFF ball-bearing sliding rail kit (P/N 679365-001 / 737412-001; see the DL380 G8/G9 2U SFF sliding rail kit), the optional Universal Media Bay (PN 724865-B21) for front VGA and USB, the rear-2-SFF kit for boot placement, and the GPU power-cable kit (PN 669777-B21) on accelerator builds.
• Platform notes: CPU hot-plug is not supported, and v3/v4 CPUs cannot be mixed. NVMe via the Express Bay option consumes specific front-bay positions, which is a tighter tradeoff at eight bays than at sixteen or twenty-four. Confirm FlexibleLOM and drive-backplane compatibility against the specific build at quote time.

Our Assessment

Where it excels: The eight-bay DL380 Gen9 is the right answer for compute-driven dual-socket workloads where primary storage is networked. It is a strong fit for VM cluster nodes with SAN-backed datastores, application and middleware servers with modest local data, mid-tier SQL Server and Oracle hosts whose datafiles live on SAN, domain controllers and infrastructure services, branch-office and ROBO deployments, and lab or staging environments mirroring Gen9 production. When the workload does not need a large local SSD pool, paying for sixteen or twenty-four bays is wasted budget, and the eight-bay build delivers the same Gen9 platform for less.

Where to look instead: If the workload needs a large local storage tier, the DL380 Gen9 16-Bay 2.5" is the SFF sweet spot and the DL380 Gen9 24-Bay 2.5" is the maximum-density option; for bulk HDD capacity, the DL380 Gen9 12-Bay 3.5" is purpose-built. New mission-critical deployments that need iLO 5 Silicon Root of Trust, PCIe Gen4, or DDR4-2933+ bandwidth should move to the DL380 Gen10 16-Bay 2.5". Budget-driven 2U Gen9 deployments that can trade SFF for LFF should compare the HPE ProLiant DL180 Gen9 LFF value tier. Dell-standardized shops should compare the Dell PowerEdge R730 8-Bay 2.5", the equivalent 2U Grantley platform at the same bay count.

Bottom line: The eight-bay DL380 Gen9 is the cost-disciplined member of the family - the build you choose when the compute is the point and the storage lives on the network. The typical customer is an IT team adding SAN-backed VM cluster nodes to an existing Gen9 estate, standing up application or infrastructure servers, or deploying branch and ROBO sites where local capacity is modest. Buy it when eight bays genuinely cover the local-storage requirement; step up to the 16- or 24-bay companions the moment a large local SSD pool is in the picture, and step to Gen10 when current-generation security and memory bandwidth matter.

Honest Limitations

• Same Gen9 platform limitations as the rest of the family. HPE active warranty has ended; iLO 4 has no Silicon Root of Trust; DDR4 speed caps at DDR4-2400 (v4) or DDR4-2133 (v3) and drops further under full DIMM population; PCIe Gen3 only; the FBWC battery is a wear item; v3/v4 CPU mixing is not supported; and HPE Smart Memory is required for rated speeds.
• Boot-drive consumption hurts more at eight bays. Two bays for an OS RAID 1 mirror is 25% of the budget, so rear-bay or M.2 boot is strongly preferred on builds where data capacity matters.
• Future expansion to 16 or 24 bays requires backplane and cage kits. The field upgrade is supported but not trivial - if the workload may grow into more bays within the platform's service life, start at the 16- or 24-bay variant to avoid the expansion exercise.
• NVMe consumes bay count. The Express Bay NVMe option occupies physical front-bay positions, so on the eight-bay build the storage budget tightens further when NVMe-tier performance is required.

Workload Fit

Where to Look Instead

• Need more SFF bays at Gen9? → DL380 Gen9 16-Bay 2.5" - the SFF sweet spot for VDI, HCI, and database hosts with local SSD.
• Need maximum SFF density at Gen9? → DL380 Gen9 24-Bay 2.5" - 24 SFF bays at Gen9.
• Need LFF (3.5") drives for bulk capacity? → DL380 Gen9 12-Bay 3.5" - high-capacity NL-SAS HDD pool.
• Want a lower-cost 2U Gen9 value tier? → HPE ProLiant DL180 Gen9 LFF - cost-optimized 2U dual-socket Gen9.
• Need Gen10 with iLO 5, DDR4-2933, and Silicon Root of Trust? → DL380 Gen10 16-Bay 2.5" - current-generation 2U.
• Dell shop alternative at the same Gen9 dual-socket 2U tier? → Dell PowerEdge R730 8-Bay 2.5" - 2U 2S Grantley, equivalent positioning.
• Mounting hardware? → DL380 G8/G9 2U SFF sliding rail kit (P/N 679365-001 / 737412-001).
