DL20 Gen11 at a glance

Processors

One processor: Intel Xeon 6300 (6315P to 6377P), Xeon E-2400 (E-2414 to E-2488) or Pentium G7400. With a 95W processor, such as the Xeon 6369P or E-2488, HPE integrates an additional CPU baffle.

Memory

4 DIMM slots on 2 channels. DDR5-4800 ECC UDIMMs only, 16GB or 32GB; no RDIMMs, LRDIMMs or non-ECC UDIMMs. Up to 128GB with 32GB in all four slots.

With one DIMM per channel the kits run at 4400 MT/s. With two DIMMs in a channel, as at 128GB, HPE lists 3600 MT/s (32GB) or 4000 MT/s (16GB). Both DIMMs in a channel must be the same capacity, and HPE does not recommend mixing capacities at all; it recommends 1, 2 or 4 DIMMs. DL20 Gen11 Memory

Drives

Up to 6 SFF drives in the 4SFF model: 4, plus 2 with the 2SFF HDD Enablement Kit (P65406-B21), which cannot be fitted with an optical drive. 2 LFF drives in a 2LFF model, hot-plug or non-hot-plug.

Up to two U.3 NVMe SSDs, only in the 2SFF cage and only below 25°C ambient. SAS 24G drives run at 12G except in the 2SFF cage.

Up to two M.2 NVMe SSDs, which need the Serial Port/iLO/M.2 Enablement Kit (P65407-B21); Smart Array controllers do not support M.2. The NS204i-u boot device needs its cable kit (P65410-B21). DL20 Gen11 Drives

Storage controllers

Embedded Intel VROC SATA RAID, disabled by default, UEFI boot mode only, no VMware; a RAID set cannot span SFF and M.2 drives or two drive cages. MR216i-p, MR216i-o and MR408i-o tri-mode controllers, which the 2LFF non-hot-plug model does not support.

A tri-mode controller needs a cable kit: P65412-B21 for an OCP controller, P65413-B21 for the PCIe MR216i-p. For the 2SFF cage, the MR216i-p needs P65414-B21 and the MR216i-o P65415-B21; HPE lists P65416-B21 for select OCP controllers with the 2SFF kit, without naming them.

The Smart Array E208e-p is for external storage only. One 96W Smart Storage Battery (P01366-B21) at most. DL20 Gen11 Storage Controllers

Networking

Four embedded 1GbE ports, port 1 shared with iLO. A dedicated iLO port comes with the Serial Port/iLO/M.2 Enablement Kit (P65407-B21). OCP 3.0 adapters need the External OCP Cable Kit (P65411-B21); one PCIe and one OCP network adapter at most. No SR-IOV. DL20 Gen11 Networking Adapters

Expansion

One PCIe 5.0 x16 slot, full height, half length, on the x16 FHHL Riser Kit (P52753-B21), which HPE makes mandatory. An external OCP 3.0 slot takes a network adapter and an internal OCP slot a storage controller, and both can be used together. Riser cards

Power

One 290W non-redundant ATX power supply, factory-installed only and needing the ATX enablement kit (P65409-B21), or one or two Flex Slot hot-plug supplies: 500W Platinum, 800W Titanium, 1000W Titanium or 800W -48VDC. A second supply must have the same part number as the first. DL20 Gen11 Power Supplies

Management

HPE iLO 6.

Specifications from HPE QuickSpecs a50007009enw, version 29 (October 5, 2026). Memory figures match the DL20 Gen11 Memory page.

Before you order memory, check that it is unbuffered (UDIMM). The DL20 Gen11 takes only HPE DDR5-4800 unbuffered ECC DIMMs: the 16GB P64336-B21 and the 32GB P64339-B21. Registered DIMMs (RDIMMs) and LRDIMMs are not supported, and HPE does not qualify memory from earlier server generations in it, such as the DL20 Gen10's DDR4 UDIMMs. Before you reuse or order a kit, type the part number from its label into the check on this page to see whether it is on the DL20 Gen11 list.

Gen10 or Gen11? How to tell

The processor model number tells the two DL20 generations apart, and it decides the memory you can buy.

DL20 Gen11 parts questions

How much memory does the DL20 Gen11 support?

Up to 128GB: 32GB DDR5-4800 unbuffered ECC DIMMs (UDIMMs) in all four slots. Registered and load-reduced DIMMs are not supported. With one DIMM per channel the kits run at 4400 MT/s. With two DIMMs in a channel, as at 128GB, HPE lists 3600 MT/s for 32GB kits and 4000 MT/s for 16GB kits. The two DIMMs in a channel must be the same capacity.

Which drives fit the DL20 Gen11?

2.5-inch SFF drives on the Basic Carrier (BC) in the 4SFF model, SAS or SATA, and up to two U.3 NVMe SSDs in the optional 2SFF cage; 3.5-inch LFF hard drives on the Low Profile (LP) carrier and LFF SSDs on the LPC carrier in the 2LFF hot-plug model; and LFF RW SATA drives, HPE's non-hot-plug drives, in the 2LFF non-hot-plug model. M.2 NVMe SSDs fit with the Serial Port/iLO/M.2 Enablement Kit. SAS drives need a tri-mode controller, which the non-hot-plug model does not support.

How do I tell which processor my DL20 Gen11 has?

Read the processor model in iLO under System Information › Processors. Xeon 6300 models are numbered 63xxP (such as 6315P), Xeon E-2400 models E-24xx (such as E-2434), and the Pentium is the G7400. All of them take the same DDR5-4800 UDIMM kits. With a 95W processor, HPE integrates an additional CPU baffle.

Is my server a DL20 Gen11 or a DL20 Gen10?

Check the processor model number and the memory. The Gen11 runs a Xeon 6300 (63xxP, such as 6315P), Xeon E-2400 (E-24xx, such as E-2434) or Pentium G7400 processor with DDR5 UDIMMs. The Gen10 runs a Xeon E-2200 (E-22xx, such as E-2224), Core i3-9100 or Pentium G5420 with DDR4 UDIMMs. Both have 4 DIMM slots, so the slot count does not tell them apart. SFF drives differ too: Basic Carrier (BC) for the Gen11, Smart Carrier (SC) for the Gen10. Memory, processors and SFF drives differ between them, so check a part number against the list for your generation before you order.

Are refurbished parts on this list too?

Yes. A refurbished part carries the same HPE part number as a new one, so it is listed here under that number, and each listing shows its condition. Every part ships tested or factory sealed.

What warranty comes with DL20 Gen11 parts?

A replacement warranty of 1 to 5 years, depending on the part: memory is covered for 5 years, and many other parts for 1 or 3 years.

  • Maximum of two NVMe U.3 is allowed per configuration.
  • NVMe U.3 drives can be selected only if P65406-B21 – HPE ProLiant DL20 Gen11 2SFF HDD Enablement Kit is selected.
  • NVMe U.3 drives should be restricted to <25°C/77°F ambient temperature environments only. Fan speed results of these drives in ambient temperature environment more than suggested levels may result in acoustic noise levels unsuitable for any environments outside of Data Center environments.

Memory2 parts

All memory on the DL20 Gen11 Memory page

HPE notes (4)
  • HPE memory from previous generation servers is not qualified or warranted with this HPE ProLiant Server.
  • With one processor installed, four DIMMs slots are available, two slots per channel. Each channel can be populated with one DIMM (1DPC) or two DIMMs (2DPC).
  • The quantity of memory DIMMs selected is recommended to be 1, 2 or 4 for balanced performance.
  • Symmetric configurations are required within each channel (e.g., 1R/1R, 2R/2R), meaning the same DIMM capacity (16GB or 32GB) is required when populating within each channel.
Unbuffered DIMMs (ECC UDIMMs)
HPE notes (2)
  • The -B21 memory SKUs shown in this document are to be used when ordering stand-alone memory only. For each -B21 SKU, there is a corresponding -F21 SKU which is to be used when configuring servers with integrated memory DIMMs.
  • Running at up to 4400 MT/s with Intel Xeon processors when two dual-rank DIMMs are installed in different channels.
