HPE ProLiant DL360 Gen10 Upgrade Guide: RAM and Storage

Updated Oct. 7, 2026 · Written from this device's verified specifications

This guide covers memory and drive upgrades for the HPE ProLiant DL360 Gen10. The short answer: it takes up to 24 HPE DDR4 SmartMemory DIMMs, and its drive bays are fixed by the chassis and backplane, so you can swap drives but not add bays.

At a glance

  • 24 DDR4 DIMM slots, 12 per CPU, so a single-CPU server has 12 usable slots.
  • Up to 3 TB with 128 GB LRDIMMs, or about 1.5 TB with 64 GB RDIMMs. Never mix RDIMM and LRDIMM.
  • 2933 MT/s needs 2nd-gen Xeon Scalable CPUs. 1st-gen CPUs run memory at 2666 MT/s.
  • Drive bays are 8 SFF (2.5 inch), 10 NVMe SFF or 4 LFF (3.5 inch), depending on your exact SKU.
  • NVMe drives and all expansion slots run at PCIe 3.0.

RAM: DDR4 SmartMemory RDIMM and LRDIMM

The DL360 Gen10 has 24 DIMM slots: 12 per processor, arranged as 6 channels per CPU with 2 DIMMs per channel. It takes full-size DDR4 registered ECC memory only, either HPE DDR4 SmartMemory RDIMM or LRDIMM. There are no SO-DIMM slots, and no memory is soldered to the board, so all capacity lives in the DIMM slots.

The largest module is 128 GB, and that size is LRDIMM only. RDIMMs top out at 64 GB. Fully populated, that means 3 TB (24 x 128 GB LRDIMM) or 1,536 GB (24 x 64 GB RDIMM, which HPE rounds to 1.54 TB). Both figures assume 2nd-gen Xeon Scalable CPUs at 2933 MT/s. RDIMM and LRDIMM cannot be mixed, and doing so can halt the server during BIOS initialization.

Your CPU sets the real limits. 1st-gen Xeon Scalable CPUs run memory at DDR4-2666, and 2nd-gen CPUs at DDR4-2933. Each CPU also has its own memory cap. For example, a Bronze 3104 supports only 768 GB at 2133 MT/s. Per-CPU caps are 1.5 TB for 1st-gen M models, and 2 TB or 4.5 TB for 2nd-gen M and L models. With one CPU installed you only have 12 usable slots, so the totals above are halved.

The user guide's part-number decoder mentions unbuffered ECC (UDIMM), but the QuickSpecs list only RDIMM and LRDIMM as supported. Treat UDIMM as unsupported unless HPE confirms otherwise.

Special memory exists but is restricted by CPU generation. NVDIMMs (up to 12 x 16 GB) work only with 1st-gen CPUs and can be mixed only with RDIMMs. HPE Persistent Memory (up to 12 x 512 GB, at 2666 MT/s) works only on certain 2nd-gen CPUs: Platinum 8200, Gold 6200, Gold 5200 and Silver 4215/4215R.

Buying tips

  • Buy HPE-qualified DDR4 SmartMemory, not generic modules.
  • Pick RDIMM or LRDIMM and stick with one type across the whole server.
  • Check your CPU generation first: 2933 MT/s modules only run at that speed on 2nd-gen CPUs.
  • On a single-CPU server, plan around 12 slots, not 24.
  • Check your CPU's own memory cap before buying 128 GB modules.

Storage: front drive bays and the optional M.2 riser

The number and type of front bays is fixed by the chassis and backplane. Configurations are 8 SFF (2.5 inch), 10 NVMe SFF, or 4 LFF (3.5 inch). SFF bays take SATA, SAS or NVMe drives, while LFF bays take SATA or SAS. You can swap drives within the bays you have, but you cannot convert the server from one layout to another. Confirm your exact SKU before buying drives.

An optional universal media bay can add 2 more SFF drives, and an optional rear drive is also possible. These, along with NVMe support, need specific HPE options. NVMe drives run at PCIe 3.0.

HPE's QuickSpecs list these largest configurations: 26.4 TB of SAS HDD (8+2+1 x 2.4 TB), 22 TB of SATA HDD (8+2+1 x 2.0 TB), 168.3 TB of SAS SSD (8+2+1 x 15.3 TB), 84.48 TB of SATA SSD (8+2+1 x 7.68 TB), 153.6 TB of NVMe SSD (10 x 15.36 TB), and for 3.5 inch bays 72 TB of HDD (4 x 18 TB) or 7.68 TB of SSD (4 x 1.92 TB).

M.2 is available only through the optional SATA M.2 primary riser (part 867978-B21). Its connectors are SATA, not NVMe. M.2 lengths are not confirmed, so check the QuickSpecs or user guide before buying a card. The two embedded SATA ports used for M.2 reduce the S100i's usable drive bays from 14 to 12.

The standard S100i software RAID runs in UEFI mode only, is off by default and supports Windows Server only. HPE points Linux users to an open-source RAID 1 boot solution. Legacy boot needs an extra controller and part 758959-B22 on CTO orders. Other controller options are the E208i-a/p, E208e-p, P408i-a/p, P408e-p and P816i-a Smart Array controllers. The -a types are HPE's proprietary modular design. If you plan to fit a GPU, order the LH (low-heatsink) controller variants. Drive thickness limits are not confirmed.

Buying tips

  • Match the drive size (2.5 or 3.5 inch) and interface to your bays before anything else.
  • NVMe only works with the right backplane and options, so check your SKU first.
  • Don't buy an M.2 SATA card without confirming its length in HPE's documents.
  • On Linux, don't count on the S100i for RAID; consider a Smart Array controller.
  • Check drive thickness against HPE's documents if you are unsure, since the limit isn't confirmed.

How to upgrade

Before you start

  • Find your exact SKU and check how many CPUs are installed and which generation they are.
  • Check whether your drive bays are 4 LFF, 8 SFF or 10 NVMe SFF.
  • Back up all important data and note your RAID configuration.
  • Update the BIOS and firmware if HPE's documents for your part recommend it.
  • Keep the HPE user guide handy for exact disassembly and DIMM population order.

Steps

  1. Back up your data
    Make a full backup of the server and note any RAID or boot settings before you touch the hardware.
  2. Power off and unplug
    Shut the server down properly, then disconnect all power cords and cables.
  3. Ground yourself
    Use an anti-static wrist strap or touch bare metal on the chassis before handling parts. Hold DIMMs and drives by their edges.
  4. Open the server
    Follow the HPE user guide for how to slide the server out of the rack if needed and remove the access panel. Disassembly details differ by option, so check the guide.
  5. Install the part
    For memory, use the slots and population order given in the user guide, and use one memory type throughout. For drives, fit them in the matching bay type. For an M.2 card, use the optional SATA M.2 riser.
  6. Close and reconnect
    Refit the access panel, return the server to the rack, then reconnect cables and power.
  7. Check that it is recognized
    Power on and confirm that the BIOS or system utilities show the new memory capacity or drive. If you installed a drive on the S100i, remember it is off by default and works only in UEFI mode.

Good to know

  • This guide covers RAM and drives only. Details on which CPUs you can swap in aren't confirmed here, so check HPE's QuickSpecs and user guide before buying a processor.
  • Drive thickness limits, memory-card slots (such as an internal microSD or USB option) and exact M.2 lengths are not confirmed.
  • The optional SATA M.2 riser is listed as providing SATA M.2 connectors, but the supported lengths are not confirmed.
  • The 3 TB and 1.54 TB maximums assume 2nd-gen CPUs at 2933 MT/s, and your CPU's own cap may be lower.
  • Use HPE-qualified SmartMemory, and check your exact SKU before buying drives or controllers.

Frequently asked questions

How much RAM can the HPE ProLiant DL360 Gen10 take?

Up to 3 TB with 24 x 128 GB LRDIMMs, or 1,536 GB (HPE rounds this to 1.54 TB) with 24 x 64 GB RDIMMs. These figures assume two 2nd-gen Xeon Scalable CPUs. With one CPU you have only 12 slots, and each CPU has its own memory cap.

What type of RAM does the DL360 Gen10 use?

DDR4 HPE SmartMemory, either RDIMM or LRDIMM, as full-size DIMMs. You cannot mix the two types. The user guide mentions unbuffered ECC, but HPE's QuickSpecs list only RDIMM and LRDIMM as supported.

What memory speed does the DL360 Gen10 run at?

It depends on the CPU. 1st-gen Xeon Scalable CPUs support DDR4-2666 and 2nd-gen CPUs support DDR4-2933. Some lower-end CPUs run slower; a Bronze 3104 supports 2133 MT/s.

Does the DL360 Gen10 support NVMe drives?

Yes, but only on configurations with the right backplane and options, such as the 10 NVMe SFF layout. NVMe drives run at PCIe 3.0. Confirm your exact SKU before buying.

Can I add M.2 drives to the DL360 Gen10?

Only through the optional SATA M.2 primary riser (part 867978-B21). Its connectors are SATA, not NVMe. M.2 lengths aren't confirmed, and using it reduces the S100i's usable drive bays from 14 to 12.

Can I add more drive bays or change from 3.5 inch to 2.5 inch?

No. The bay count and type are fixed by the chassis and backplane. The optional universal media bay can add 2 SFF drives, and an optional rear drive is also possible, but both need specific HPE options.
