01 — Overview

The DL365 Gen11 at a glance

Our read of HPE’s documentation: where the DL365 Gen11 is strong, and the limits worth knowing before you spec one.

Strengths

Two EPYC sockets in one rack unit: up to 320 cores and 24 DDR5 slots (6 TB), with 160 PCIe 5.0 lanes across the pair.
Forty processors over both EPYC 9004 and 9005, among them the 1,150 MB-cache 9684X and the two 5 GHz F-series parts (9575F and 9175F).
Twenty E3.S NVMe bays in the EDSFF chassis, or ten tri-mode SFF bays in the 8SFF chassis.
Direct liquid cooling is on the option list as a cold-plate module, and HPE’s thermal matrix rates its liquid-cooled 400 W rows for 35 °C in all three chassis.
A GPU chassis with two front full-length slots for the NVIDIA A16, L4 or RTX PRO 4500.

Watch-outs

With one processor only 12 of the 24 DIMM slots work, and the EDSFF chassis and the liquid-cooling module both require two processors.
Hot processors cost drive bays: HPE’s rules cap processors of 320 W or more at 8 SFF or 12 E3.S drives, although its thermal matrix also lists 10 SFF and 20 E3.S fronts at 400 W with liquid cooling.
256 GB modules are held to 25 °C and capped at 16 in the EDSFF chassis (20 with liquid cooling) and 20 in the GPU chassis, so 6 TB needs the SFF chassis.
Only two rear PCIe slots; the NS204i-u turns slot 2 into a low-profile slot, and the PCIe-fed liquid-cooling module takes slot 2 altogether.
Parts of the QuickSpecs contradict each other — the −48 V DC supply’s input rating, the 3 TB versus 6 TB memory statements and the drive cap for hot processors are examples — so we confirm those points at quotation.

Up to 240 W, HPE pairs the Standard heat sink with Standard fans for eight SAS/SATA drives and with Performance fans for ten SAS/SATA drives or any NVMe. Other rules pull the other way: any U.3 x4 cage calls for the Performance heat sink (or liquid cooling) and seven Performance fans, the EDSFF chassis needs the Performance heat sink or liquid cooling at any wattage, and HPE’s thermal matrix gives the GPU chassis no Standard heat sink row. Above 240 W: Performance heat sink and Performance fans, or the liquid-cooling module.
HPE caps processors of 320 W and above at eight SFF or twelve E3.S drives and requires liquid cooling for them in the EDSFF chassis; its thermal matrix nonetheless lists a 12-drive E3.S build at 400 W on air at 25 °C, and 10 SFF or 20 E3.S at 400 W with liquid cooling.
Both processors must be the same model, and processor option kits include neither heat sink nor fans.
A one-processor server uses five fan kits and a two-processor server seven; each 1U Gen11 fan kit holds one fan.
EPYC 9734 (112 cores, 340 W): printed among the 4th Gen specifications, yet absent from the orderable processor kits.
5th Gen processors need the NS204i-u v2 boot device (P78279-B21) rather than the original NS204i-u.

03 — Memory

24 DIMM slots, 12 per processor

Twenty-four DDR5 RDIMM slots, 12 per processor, one on each of its 12 channels. With a single processor only its 12 slots are usable; HPE’s CTO notes state that all 24 need two processors. EPYC 9005 takes the DDR5-6400 kits and EPYC 9004 the DDR5-4800 kits, each list running from 16 GB to 256 GB.

HPE states the ceiling three ways: 6.0 TB (24 × 256 GB) in the memory table, 3 TB per processor and 6 TB per pair in the processor notes, and “up to 3 TB of memory per server” in a memory note. A one-processor build reaches 3 TB (12 × 256 GB) on paper, but 256 GB modules call for seven Performance fans while HPE lists five fan kits for one processor.
At 25 °C HPE allows 24 × 256 GB in the SFF chassis, but 16 in the EDSFF chassis and 20 in the GPU chassis (24, 20 and 20 with liquid cooling). Its ambient table clears 16, 32, 64 and 128 GB modules for all 24 slots at 35 °C in every chassis; the 96 GB module is not listed in it.
128 GB and 256 GB modules require the Performance heat sink and seven Performance fans; with InfiniBand NDR adapters on air, 256 GB modules are limited to 12.
The 96 GB and 128 GB 2Rx4 kits cannot be mixed with any other memory, and neither x4 with x8 nor 3DS with non-3DS is allowed.
LRDIMMs and persistent memory are unsupported; the RAS features listed are Advanced ECC and Online Spare.

7 drive-cage kits, up to 20 bays

Three chassis, and no rear cages in any factory build. The 8SFF chassis takes one 8-bay tri-mode backplane and an optional 2-bay one for ten SFF drives; the EDSFF chassis ships with a 20-bay E3.S cage; the GPU chassis keeps 8 E3.S or 4 SFF bays beside its front GPU slots. The layouts below are complete configurations; the chart after them plots each backplane kit.

HPE ProLiant DL3X5 Gen11 NS204i-u NVMe Hot Plug Boot Device Cable Kit (P57013-B21) — boot

HPE’s CTO table marks rear drive cages as not available for factory builds, adding that field upgrades may differ, so every factory-fitted bay is at the front.
HPE’s AMD Gen11 servers have no software RAID option, so RAID comes from the MR and SR controllers; the OCP-mounted (OROC) ones take up an OCP slot.
The standard 8SFF and 2SFF backplanes are U.3 tri-mode for SATA, SAS and NVMe; U.2 backplanes are private options only and take neither SAS/SATA nor static drives.
Without a tri-mode controller, NVMe and SAS/SATA drives cannot share a cage.
GPU-chassis cages attach directly to the motherboard, and the 4SFF x2 OCP bundle requires an MR408i-o. HPE’s cable-kit list nonetheless pairs the 4SFF cage with an MR416i-o or MR416i-p and the 8-bay E3.S cage with an SR932i-p.
A single optical drive is supported on the 8SFF chassis and needs the 2SFF DisplayPort ODD blank kit.

GPUs, PCIe and networking

GPUs fit only the GPU chassis, whose front GPU riser slots 4 and 5 are full-length PCIe 5.0 x16 — one wired to each processor — alongside 8 E3.S or 4 SFF drives. HPE lists the NVIDIA A16 64 GB, L4 24 GB and RTX PRO 4500 Blackwell 32 GB; two cards must be the same model, and the A16 (8-pin) and RTX PRO 4500 (16-pin) each need a CPU power cable kit per card. Up to 2 single-width or 2 double-width cards of one model, GPU chassis only.

Slot 1 hangs off processor 1 and slot 2 off processor 2; the GPU risers split the same way, slot 4 on processor 2 and slot 5 on processor 1.
The processor limits slot 2 with slot 4, and slot 5 with OCP slot 21, to 112 GB/s combined.
Fitting the NS204i-u makes slot 2 a low-profile slot (riser P55029-B21); the standard secondary option is the 1U x16 riser kit (P56915-B21).
The 1P OCP cable (one processor only) takes OCP1 to x16 but then allows just one OCP card; the 2P cable takes both OCP slots to x16, needs two processors and excludes the secondary riser upgrade.
The PCIe-fed liquid-cooling module occupies slot 2, cutting the PCIe card limit from two to one.
An XGMI interconnection cable kit (P63125-B21) is offered for two-processor 8SFF builds.

06 — Power & cooling

5 power supplies, 800–2,200 W

Five Flex Slot supplies are listed, and a server takes one or two of the same part. For AC there are two Platinum models, 800 W and 1600 W, and two Titanium models, 1000 W and 1800–2200 W; the fifth is a 1600 W unit for −48 V DC.

AC277 VAC / HVDC

Neither the 1600 W Platinum unit nor the 1800–2200 W Titanium unit runs below 200 V; both are high-line only.
HPE’s notes on the DC supply disagree: one says 200–240 V AC input only, another 277 V AC/380 V DC, while its name says −48 V DC. Its kit notes disagree too: one accepts the DC power lug kit (P36877-B21) or a DC power cable kit, while the supply’s own note makes the lug kit mandatory.
A note beside the 1000 W Titanium unit describes Flex Slot Platinum Plus supplies at up to 94%; the standard-features list gives that unit 96%.
Output tables cover the 800 W and 1600 W supplies and a 500 W unit that is not offered for this server.

09 — Use cases

Five builds that suit the DL365 Gen11

Five DL365 Gen11 builds across HPE’s three chassis, including one single-socket starter, all drawn from this model’s options in our configurator. Open any of them to edit; fan counts, cabling and ambient limits are confirmed with HPE’s rules at quotation.

VDI

Two-A16 virtual desktop node

HPE names VDI among the DL365 Gen11’s target workloads. Two NVIDIA A16 cards (128 GB of GPU memory) sit in the front GPU slots, and a pair of 210 W processors keeps the GPU chassis inside the 240 W row of HPE’s thermal matrix, which is rated for 35 °C.

2 × AMD EPYC 9335 — 32 cores @ 3 GHz, 210 W each
2 × NVIDIA A16 64 GB (non-CEC) in the front GPU slots
24 × 64 GB DDR5-6400 RDIMM — 1.5 TB across both sockets
8 × 7.68 TB E3.S NVMe on the GPU-chassis backplane
NS204i-u mirrored M.2 boot
Broadcom BCM57414 2 × 25GbE SFP28 OCP 3.0
2 × 1600 W Flex Slot Platinum (200–240 V only)
Windows Server 2025 Datacenter

Each A16 needs the 8-pin CPU GPU power cable kit (P56919-B21), and the two cards must match. The GPU chassis runs Performance fans and, in that 240 W row, the Performance heat sink, and is 81.84 cm deep; the NS204i-u needs seven fans and the low-profile secondary riser.

Virtualisation

320-core, 6 TB 1U host

Two EPYC 9845s give 320 cores, and 24 × 256 GB modules fill every channel for 6 TB — the full memory ceiling, which HPE allows in the SFF chassis. Eight NVMe drives stay within the drive cap for 320 W-plus processors.

2 × AMD EPYC 9845 — 160 cores @ 2.1 GHz, 390 W each
24 × 256 GB DDR5-6400 3DS RDIMM — 6 TB
8 × 3.84 TB NVMe U.3 on the 8SFF tri-mode backplane — 30.72 TB raw
NS204i-u mirrored M.2 boot
Broadcom BCM57608 2 × 100GbE QSFP112 OCP 3.0
2 × 1800–2200 W Flex Slot Titanium (200–240 V only)
Red Hat Enterprise Linux 9, 3-year subscription

This is a 25 °C build: HPE’s thermal matrix rates eight drives with processors above 300 W at 25 °C on air, and its DIMM table holds 256 GB modules to 25 °C with or without liquid cooling. The 256 GB modules also need the Performance heat sink and seven Performance fans, and 24 of them are allowed only in the SFF chassis.

Open this build in the configurator →

EDA & CAD

High-clock engineering compute node

HPE lists EDA and CAD among its target workloads. Two EPYC 9175F processors run 16 cores each from a 4.2 GHz base with 512 MB of cache apiece (1 GB in the server), and 24 × 128 GB modules put 96 GB of memory behind every core.

2 × AMD EPYC 9175F — 16 cores @ 4.2 GHz, 320 W each
24 × 128 GB DDR5-6400 RDIMM — 3,072 GB
8 × 3.84 TB NVMe U.3 scratch — 30.72 TB raw
NS204i-u mirrored M.2 boot
Broadcom BCM57414 2 × 25GbE SFP28 OCP 3.0
2 × 1600 W Flex Slot Platinum
Red Hat Enterprise Linux 9

The 320 W processors cap the chassis at eight SFF drives and need the Performance heat sink and fans, or the liquid-cooling module; the 128 GB modules also require seven Performance fans. On air this is a 25 °C build: HPE’s thermal matrix rates eight SFF drives with processors above 300 W at 25 °C, although its DIMM table clears 24 × 128 GB for 35 °C.

Open this build in the configurator →

NVMe storage & analytics

20-bay E3.S node in 1U

Twenty E3.S NVMe bays in one rack unit — 153.6 TB raw with 7.68 TB drives — driven by two 32-core 210 W processors, a pairing HPE’s thermal matrix rates at 35 °C with Performance heat sinks and fans.

2 × AMD EPYC 9335 — 32 cores @ 3 GHz, 210 W each
20 × 7.68 TB E3.S NVMe — 153.6 TB raw
24 × 64 GB DDR5-6400 RDIMM — 1.5 TB
NS204i-u mirrored M.2 boot
Broadcom BCM57608 2 × 100GbE QSFP112 OCP 3.0
2 × 1600 W Flex Slot Platinum
SUSE Linux Enterprise Server 15

The EDSFF chassis always needs two processors, Performance heat sinks (or liquid cooling) and Performance fans. Moving to 320 W-plus processors cuts the populated bays to 12 under HPE’s rules, and 256 GB modules stop at 16 in this chassis.

Open this build in the configurator →

General purpose

One-socket 1U file and application server

A one-processor DL365 Gen11 uses 12 of the 24 DIMM slots and, by HPE’s fan table, five fan kits. Slot 2 is wired to the absent second processor, so the RAID card takes slot 1 and the network adapter an OCP bay, leaving a 16-core, 200 W file and application server in one rack unit.

1 × AMD EPYC 9135 — 16 cores @ 3.65 GHz, 200 W
12 × 32 GB DDR5-6400 RDIMM — 384 GB on one socket
8 × 3.84 TB SATA SSD on the 8SFF front backplane
HPE MR416i-p Gen11 PCIe controller, 8 GB cache, in slot 1
Broadcom BCM57416 2 × 10GBASE-T OCP 3.0
2 × 800 W Flex Slot Platinum
Windows Server 2025 Standard

The configurator’s 8SFF cage stands in for HPE’s x1 tri-mode backplane (P55020-B21) with its PCIe x1 cable kit (P56903-B21); the x4 backplane would bring the Performance heat sink and seven Performance fans. HPE’s networking notes also say almost all PCIe networking cards need seven Performance fans, leaving exceptions to its configurator, against five fan kits for one processor, so the fan fit is confirmed at quotation. The NS204i-u is left out because it needs seven fans.

12 — FAQ

DL365 Gen11 questions, answered from the documentation

What is the maximum memory of the HPE ProLiant DL365 Gen11?

6 TB, using 24 × 256 GB RDIMMs with both processors fitted. Each processor has 12 slots and 12 channels, so a one-processor server tops out at 3 TB on paper, although 256 GB modules call for seven fans and HPE lists five for one processor. The 256 GB modules are also thermally limited: HPE allows 24 in the SFF chassis at 25 °C but only 16 in the EDSFF chassis and 20 in the GPU chassis.

Does the DL365 Gen11 need two processors?

No — it runs with one or two, and two must be the same model. A single processor leaves 12 of the 24 DIMM slots usable and uses five fan kits. The EDSFF chassis, the liquid-cooling module, the 2P OCP cable and the XGMI cable kit all require two processors.

Which processors does the DL365 Gen11 support?

HPE lists 40: 21 AMD EPYC 9005 and 19 EPYC 9004 models, with core counts between 8 and 160 and default cTDPs between 125 and 400 W, among them the large-cache X-series 9684X, 9384X and 9184X. The 9734 appears in the specification table without an orderable option kit.

How many drives does the DL365 Gen11 hold?

Ten SFF drives (8 + 2) in the 8SFF chassis, 20 E3.S drives in the EDSFF chassis, or 8 E3.S or 4 SFF in the GPU chassis. HPE offers no rear cages in factory builds. With processors of 320 W or more, its configuration rules limit the server to eight SFF or twelve E3.S drives.

How many GPUs does the DL365 Gen11 support?

Two, in the front GPU slots of the GPU chassis only — either two single-width or two double-width cards of the same model. HPE lists the NVIDIA A16 64 GB, L4 24 GB and RTX PRO 4500 Blackwell 32 GB; the A16 and RTX PRO 4500 each need a CPU power cable kit per card.

How many PCIe and OCP slots does the DL365 Gen11 have?

Two rear PCIe 5.0 x16 slots — slot 1 on processor 1 and slot 2, full height or low profile, on processor 2 — plus two OCP 3.0 slots that run at x8 unless an upgrade cable takes them to x16. The GPU chassis adds full-length slots 4 and 5 at the front. Two processors provide 160 PCIe 5.0 lanes.

What power supplies can the DL365 Gen11 use?

One supply or a matching pair, chosen from five Flex Slot units: Platinum at 800 W or 1600 W, Titanium at 1000 W or 1800–2200 W, and a 1600 W unit for −48 V DC. Both of the larger AC units run only on a 200–240 V feed, and the DC unit needs HPE’s power lug kit, although one note also allows a DC power cable kit instead.

How big and heavy is the DL365 Gen11?

It is 4.29 cm high and 43.46 cm wide. Depth, measured without the front ear and power-supply handle, is 64.94 cm for the SFF chassis, 70.89 cm for EDSFF and 81.84 cm for the GPU chassis. HPE’s weights run from 12.70 kg for a minimal SFF server to 22.90 kg for a fully loaded GPU chassis.

How does the DL365 Gen11 compare with the DL345 Gen11?

Both draw on the EPYC 9004 and 9005 families. The DL365 Gen11 packs two processors and 24 DIMM slots into 1U with room for 10 SFF or 20 E3.S drives. The DL345 Gen11 trades the second socket for drive room: a single-socket 2U with 12 DIMM slots whose cages reach 34 SFF, 20 LFF or 36 E3.S bays, with space for up to six PCIe cards.

Is the HPE ProLiant DL365 Gen11 end of life?

Its QuickSpecs was revised again as version 45 on 8 September 2026, with a memory update, and states no end-of-sale or end-of-support date. HPE Tech Care comes in Basic (9 × 5, 2-hour response), Essential (24 × 7, 15-minute response) and Critical (6-hour repair commitment where available) levels. We will list any announced HPE dates in our end-of-life checker.
