HPE ProLiant Gen11 Parts — DL380/DL360 Components
Complete parts guide for HPE ProLiant Gen11 servers — DDR5 memory, Xeon 4th/5th Gen CPUs, Smart Array Gen11, OCP3 NICs, hot-swap PSUs, iLO 6, and drive caddies with HPE part numbers.
HPE ProLiant Gen11: The Current-Generation Standard
HPE ProLiant Gen11 servers launched in 2023 as the flagship of HPE's rack server lineup. Built on Intel Xeon 4th Gen Sapphire Rapids and now also supporting 5th Gen Emerald Rapids (via firmware update), Gen11 brings DDR5 memory, PCIe 5.0, OCP 3.0 networking, and HPE's iLO 6 management firmware.
This guide focuses on the DL380 Gen11 (2U) and DL360 Gen11 (1U), with HPE part numbers and compatibility notes.
Gen11 vs Gen10/Gen10+ — What Changed?
| Feature | Gen10 / Gen10+ | Gen11 |
|---|---|---|
| CPU Socket | LGA3647 (Xeon Gen1-Gen2) / LGA4189 (Xeon Gen3) | LGA4677 (Xeon Gen4-Gen5) |
| Memory Type | DDR4 RDIMM/LRDIMM | DDR5 RDIMM |
| Max Memory | 3TB (Gen10) / 8TB (Gen10+) | 8TB (DL380 Gen11) |
| PCIe Generation | PCIe 3.0 (Gen10) / PCIe 4.0 (Gen10+) | PCIe 5.0 |
| NIC Standard | FlexibleLOM (Gen10) / OCP 3.0 (Gen10+) | OCP 3.0 |
| Management | iLO 5 | iLO 6 |
| RAID | Smart Array P408i | Gen11 controllers (MR408i-o, MR416i-o, MR416i-p, SR932i-p) |
| Storage Backplane | SAS/SATA 12Gb | SAS/SATA/NVMe U.3 |
Key Takeaway: Gen11 is NOT backward compatible with Gen10 CPUs, memory, or RAID controllers. If upgrading from Gen10 to Gen11, budget for new DIMMs, CPUs, and potentially RAID cards.

Gen11 Memory — DDR5 RDIMM
Gen11 servers require DDR5 ECC RDIMM. DDR4 DIMMs from Gen10 will not fit — the DIMM key is physically different.
Supported Memory Types
| Type | Speed | Sizes | Use Case |
|---|---|---|---|
| DDR5 RDIMM 1R×8 | 4800 MT/s | 16GB | Entry density, low latency |
| DDR5 RDIMM 2R×8 | 4800 MT/s | 32GB | Standard servers |
| DDR5 RDIMM 2R×4 | 4800 MT/s | 64GB | High density standard |
| DDR5 RDIMM 4R×4 | 4800 MT/s | 128GB | High capacity |
Compatible HPE Memory Part Numbers
| HPE Part # | Capacity | Type | Speed | Notes |
|---|---|---|---|---|
| P43322-B21 | 16GB | DDR5 RDIMM 1Rx8 | 4800 MT/s | Entry configs |
| P43328-B21 | 32GB | DDR5 RDIMM 2Rx8 | 4800 MT/s | Most common |
| P43331-B21 | 64GB | DDR5 RDIMM 2Rx4 | 4800 MT/s | High density |
| P43334-B21 | 128GB | DDR5 RDIMM 4Rx4 | 4800 MT/s | High capacity |
| P64706-B21 | 32GB | DDR5 RDIMM 2Rx8 | 5600 MT/s | Gen5 Xeon optimized |
Pro Tip: DDR5 Gen11 memory runs at 4800 MT/s by default. With 5th Gen Xeon (Emerald Rapids) and 5600 MT/s DIMMs, you get an additional ~16% bandwidth gain. Check your CPU model before ordering faster DIMMs.
Population rules: Populate DIMMs starting from slot 1A, 2A in each processor's memory domain. Use matched pairs for best performance. Single-CPU configurations use processor 1 DIMM slots only.

Gen11 Processors (CPUs)
Supported Intel Xeon 4th Gen Sapphire Rapids
| Model | Cores | Base GHz | TDP | Best For |
|---|---|---|---|---|
| Xeon Gold 5420+ | 28c | 2.0 | 205W | Entry dual-socket |
| Xeon Gold 6430 | 32c | 2.1 | 270W | Mid-range general purpose |
| Xeon Gold 6448Y | 32c | 2.1 | 225W | Efficiency optimized |
| Xeon Platinum 8460Y+ | 40c | 2.0 | 300W | High density compute |
| Xeon Platinum 8480+ | 56c | 2.0 | 350W | High core count |
Supported Intel Xeon 5th Gen Emerald Rapids (via FW update)
| Model | Cores | Base GHz | TDP | Best For |
|---|---|---|---|---|
| Xeon Gold 6558Q | 32c | 3.2 | 350W | High-frequency apps |
| Xeon Gold 6548Y+ | 32c | 2.5 | 250W | Power-efficient |
| Xeon Platinum 8568Y+ | 48c | 2.3 | 350W | Core-dense VMs |
| Xeon Platinum 8592+ | 64c | 1.9 | 350W | Maximum Gen5 cores |
Key Takeaway: Gen11 shipped with Gen4 Xeon support. HPE does not support field-upgrading a Gen11 server shipped with 4th Gen Xeon to 5th Gen; 5th Gen processors require a new server order with the latest-firmware system board. Verify BIOS version before installing Emerald Rapids CPUs.
RAID Controllers — Smart Array Gen11
Gen11 introduces a completely new RAID controller family. Gen10 Smart Array P408i/P816i controllers are NOT compatible with Gen11.
Gen11 RAID Controllers
| Model | Interface | Cache | Form Factor | Best For |
|---|---|---|---|---|
| MR408i-o | 12Gb SAS/SATA | 4GB | OCP | Standard RAID |
| SR932i-p | 24Gb SAS/SATA/NVMe | 8GB | PCIe card | Mixed SAS + NVMe |
| MR416i-o | 12Gb SAS/SATA | 8GB | OCP | Broadcom-based RAID |
| MR416i-p | 12Gb SAS/SATA/NVMe | 8GB | PCIe card | Mixed SAS + NVMe PCIe |
| NS204i-u | NVMe | — | Hot-plug boot module | Boot NVMe mirror |
Pro Tip: The NS204i-u hosts 2× 480GB M.2 NVMe SSDs in a hardware RAID 1 mirror — perfect for OS boot without consuming a drive bay. Part number: P48183-B21.
HPE RAID Controller Part Numbers
| HPE Part # | Model | Description |
|---|---|---|
| P58335-B21 | MR408i-o | OCP storage controller, 4GB cache |
| P47184-B21 | SR932i-p | PCIe storage controller, 8GB flash-backed cache |
| P47777-B21 | MR416i-p | Broadcom MegaRAID PCIe |
| P48183-B21 | NS204i-u | Boot device NVMe 2× M.2 |

Power Supplies — Flex Slot Hot-Swap
Gen11 uses HPE's Flex Slot PSU standard — the same mechanical format as Gen10. However, higher-efficiency Titanium and Platinum models are recommended for Gen11's higher TDP CPUs.
Compatible PSU Models
| HPE Part # | Wattage | Efficiency | Best For |
|---|---|---|---|
| 865408-B21 | 500W | 80+ Platinum | Low-power 1-CPU DL360 Gen11 |
| P38995-B21 | 800W | 80+ Platinum | Standard 1-2 CPU DL380/DL360 |
| P38997-B21 | 1600W | 80+ Platinum | High-core, GPU-equipped DL380 |
| P03178-B21 | 1000W | 80+ Titanium | Maximum efficiency, lower OpEx |
| P44712-B21 | 1800W–2200W | 80+ Titanium | GPU-dense configurations |
Pro Tip: Always install two PSUs for redundancy (1+1). Gen11 with dual Platinum 8592+ CPUs and 3× GPUs should use 2× 1600W PSUs minimum. The 1800W–2200W Titanium PSU (P44712-B21) is for GPU-dense configurations.
OCP 3.0 Network Adapters
Gen10 used FlexibleLOM; Gen10 Plus and Gen11 use OCP 3.0. Gen10 FlexibleLOM cards are NOT compatible.
Common Gen11 OCP 3.0 NICs
| HPE Part # | Speed | Ports | Chipset | Notes |
|---|---|---|---|---|
| P10097-B21 | 10GbE | 2-port | Broadcom BCM57416 | 10GBASE-T OCP3 |
| P10115-B21 | 25GbE | 2-port | Broadcom BCM57414 | Standard Gen11 choice |
| P22767-B21 | 100GbE | 2-port | Intel E810-CQDA2 | High-bandwidth AI/NVMe-oF |
| P41614-B21 | 25GbE | 4-port | Intel E810-XXVDA4 | 4-port for software-defined networking |
Pro Tip: The OCP slot sits on the motherboard — no add-in card slot required. For most enterprise workloads, the 25GbE 2-port P10115-B21 is the right starting point.

| P52343-B21 | Easy Install Rail 5 Kit | — | DL360 Gen11 4LFF / 20EDSFF |
iLO 6 — Remote Management
iLO 6 is HPE's 6th generation integrated Lights Out management controller, standard on all Gen11 servers.
iLO 6 Key Features vs iLO 5
| Feature | iLO 5 (Gen10) | iLO 6 (Gen11) |
|---|---|---|
| Remote Console | HTML5 KVM | HTML5 KVM (improved) |
| Security | Silicon Root of Trust | Enhanced Silicon Root of Trust |
| Agentless Mgmt | AMS | AMS 2 |
| HPE Compute Ops Mgmt | Limited | Full integration |
| One-Click Firmware Update | SPP only | SPP + Compute Ops Mgmt |
iLO 6 Standard is built in to the motherboard at no extra cost. iLO 6 Advanced (full KVM, virtual media, power monitoring) is licensed — HPE part number 512485-B21 (1-server license with 1yr support).
