01 — Overview

The DL320 Gen11 at a glance

Our read of HPE’s documentation: where the DL320 Gen11 is strong, and the limits worth knowing before you spec one.

Strengths

Four chassis on one platform — 4 LFF, 8+2 SFF, 12 LFF and GPU Dense — so the same model covers a branch file server, a 1U disk shelf or an accelerator node.
The 12 LFF chassis fits twelve 3.5-inch bays into one rack unit: 240 TB raw in HPE’s own maximum-storage table, and more with the 26 TB drives now on the option list.
Two x16 PCIe 5.0 FHHL slots, a x16 OCP 3.0 bay and two embedded Broadcom 1GbE ports on every CTO model, so a basic build has networking without an add-in card.
The GPU Dense chassis carries up to four single-wide NVIDIA L4 or two double-wide A16, L40 or L40S cards at the front, and those GPUs leave both riser slots free.
One 5th Gen Xeon reaches 60 cores at 270 W, and the processor cooling rule is short: above 185 W, add the High Performance heatsink and the seven-fan kit.

Watch-outs

The memory headline overstates what you can buy: HPE prints 2.04 TB (16 × 128 GB), yet no 128 GB module is on the option lists, so 16 × 96 GB — 1.5 TB — is the largest orderable build.
Filling all 16 slots drops both the 5600 and 4800 MT/s kits to 4400 MT/s, and 96 GB modules cannot be mixed with any other size.
The 12 LFF chassis is 99.51 cm deep and needs a 1200 mm rack; direct-attach cabling reaches only ten of its twelve bays, and OCP-form RAID controllers are not supported in it.
Onboard M.2 NVMe drives run at PCIe Gen3 speed at most, and the GPU chassis’s 8-bay EDSFF cage takes only four drives when cabled direct.
Core Options also carries six Xeon 6 kits under a “(4S, 8S)” heading that the rest of the document does not support, so confirm any of them before ordering.

Above 185 W TDP a build needs the High Performance Heatsink (P52756-B21) and the High-Performance Fan Kit (P48908-B21); the GPU CTO model needs the performance heatsink whatever the processor.
Six 4th Gen parts — 6414U, 6438N, 6454S, 5420+, 5412U and 3408U — sit in the Standard Features tables with no matching option kit, so they are not orderable as the document stands.
Core Options adds six kits (6714P to 6768P) under the heading “Intel Xeon 6 Socket Scalable (4S, 8S)”, added in Version 30 of June 2025. The Overview and memory sections describe only 4th and 5th Gen Xeon, so read those six as unconfirmed for this server.
The Bronze 3508U runs PCIe at Gen4 speed only, which HPE flags for high-speed network cards; the L40S GPU cannot be combined with the 6530, 8581V or 6554S.

03 — Memory

16 DDR5 DIMM slots

The single socket addresses 16 DDR5 RDIMM slots over eight channels, up to two modules on each. The processor generation picks the kit: 5th Gen Xeon takes the DDR5-5600 modules and 4th Gen the DDR5-4800 modules, each in 16, 32, 64 and 96 GB, and the two speeds cannot be mixed.

Capacity with every slot filled

by DIMM size

Operating speed

per HPE memory tables

Processor	1 DIMM / channel	2 DIMMs / channel
5th Gen Xeon Scalable · DDR5-5600 kits	5600 MT/s	4400 MT/s
4th Gen Xeon Scalable · DDR5-4800 kits	4800 MT/s	4400 MT/s

HPE’s memory table gives 2.04 TB as 16 × 128 GB at 4800 MT/s and says every processor supports 2 TB, while the Overview quotes “up to 2 TB 5200 MT/s”. The option lists stop at 96 GB, so the largest build this QuickSpecs lets you order is 16 × 96 GB = 1.5 TB.
Each processor caps speed below the kit rating: HPE’s processor tables give per-CPU DDR5 limits between 4000 and 5200 MT/s, so a 5600 MT/s module never runs at 5600 in this server.
A 96 GB module rules out every other DIMM size in the same server and pairs only with selected processors; in the GPU CTO server, 96 GB and larger modules are supported only at 25 °C ambient or below.
Memory protection is Advanced ECC, with Online Spare mode that switches to a spare rank when one degrades.

04 — Storage

8 drive-cage kits, up to 12 bays

Each of the four CTO chassis brings its own drive cage, so the chassis you order fixes the storage ceiling. The biggest options are twelve 3.5-inch bays, or ten 2.5-inch bays using the Universal Media Bay cage, and every chassis also has two onboard M.2 sockets for boot drives.

Maximum-storage figures from HPE’s table: 240 TB in 12 LFF (12 × 20 TB), 153.6 TB of NVMe or 153.0 TB of SAS SSD in 8+2 SFF, 80 TB in 4 LFF and 61.44 TB in the GPU chassis’s EDSFF cage. The table predates the 26 TB LFF drives now in the drive list.
Controller rules: at most one PCIe internal controller and two internal controllers in total counting OCP-form cards; PCIe internal controllers are not supported in the 4 LFF chassis and OCP-form ones not in the 12 LFF chassis.
HPE names the SR932i-p as the only controller for the 8SFF x4 cage and the MR416i-p as the only one for the GPU chassis’s 4SFF cage, and any internal controller must be ordered with the 96 W Smart Storage battery or the hybrid capacitor.
The two onboard M.2 sockets take SATA or NVMe boot drives but not both (up to 2 × 1.92 TB NVMe), and NVMe M.2 runs at PCIe Gen3 at most. The hot-plug alternative is the NS204i-u, a pair of 480 GB NVMe drives mirrored by its own hardware.
Embedded Intel VROC SATA software RAID (0/1/5/10) is off by default and UEFI-only; VROC NVMe needs a Standard or Premium licence and works on the SFF models only.

05 — Accelerators & I/O

GPUs, PCIe and networking

Accelerators are really a GPU Dense feature: its front cage takes up to four single-wide NVIDIA L4 or two double-wide A16, L40 or L40S cards, and GPUs there do not use the riser slots. HPE marks the A16, L40 and L40S as GPU CTO only, so outside that chassis the L4 is the option, and the support table rates up to two L4 in the rear slots. Front cage: up to 2 × L4 or 1 × L40/A16 at 35 °C inlet, 4 × L4 or 2 × L40/A16 at 25 °C; 2 × L4 in the rear slots at 25 °C — High Performance Fan Kit throughout.

Slot 1 ships with its riser by default; the second FHHL slot needs the optional secondary riser.
In the GPU CTO server the SR932i-p, MR416i-p and Gen5 retimer card each require the secondary riser, and they cannot be mixed with one another.
Adapter options run from 4-port 1GbE to 2-port 100GbE, plus 32Gb SN1610 and 64Gb SN1700 Fibre Channel HBAs; GPUs in the front cage do not count against the two slots.

06 — Power & cooling

6 power supplies, 500–2,200 W

One or two HPE Flex Slot hot-plug supplies, from 500 W Platinum up to the largest Titanium unit, plus a 1600 W −48 V DC supply that Core Options and the power tables carry but the Standard Features list omits. The Platinum units are rated at 94% efficiency and the Titanium units at 96%. The option lists and power table call that largest unit 1800–2200 W, but the Standard Features list prints 1800–2000 W.

AC−48 V DC

The 1600 W Platinum supply needs a 200–240 VAC feed; the 1000 W Titanium is rated at its full 1000 W on both 100–127 VAC and 200–240 VAC.
With a 500 W supply the 8 SFF chassis cannot take NVMe drives, and on the 8SFF x4 backplane an internal controller becomes mandatory, limiting the bays to SAS/SATA.
Fan kits: a five-fan Standard kit, a seven-fan High Performance kit, and a two-fan “2P” kit that becomes mandatory alongside either one whenever M.2 SSDs are fitted (except in the GPU CTO server).
For UK and EU orders HPE lists the 1000 W and 1800–2200 W Titanium supplies among its 96%-efficient parts meeting the ErP Lot 9 rule.

Four builds that suit the DL320 Gen11

Four builds, one per chassis type, each inside the QuickSpecs rules for cooling, controllers and cages. Every part is on the DL320 Gen11 configurator allow-list, so each build opens in the configurator ready to edit.

Backup & archive

Twelve-bay 1U backup target

The 12 LFF chassis is the densest disk option here: twelve 3.5-inch bays in one rack unit. A PCIe MR416i-p with 8 GB of cache runs them as RAID — OCP-form controllers are not allowed in this chassis — and a 16-core Silver 4514Y at 150 W stays on the standard heatsink.

1 × Xeon Silver 4514Y — 16 cores @ 2 GHz, 150 W
8 × 32 GB DDR5-5600 RDIMM — 256 GB (4400 MT/s with this CPU)
12 × 26 TB 7.2K SAS LFF HDD — 312 TB raw
HPE MR416i-p Gen11 8 GB cache PCIe controller
NS204i-u mirrored NVMe boot (2 × 480 GB)
Broadcom BCM57414 2 × 25GbE SFP28 OCP 3.0
2 × 1000 W Flex Slot Titanium
Red Hat Enterprise Linux 9

The 12 LFF chassis is 99.51 cm deep and needs a 1200 mm rack. The NS204i-u calls for the High-Performance Fan Kit, and the cached MR416i-p needs the Smart Storage battery or hybrid capacitor.

Virtualisation

32-core NVMe hypervisor host

A 32-core Gold 6548Y+ gives one socket a generous vCPU count, and eight 64 GB DIMMs — one per channel — deliver 512 GB at the processor’s 5200 MT/s limit. Eight U.3 NVMe drives sit on the 8SFF x4 Tri-Mode backplane behind the SR932i-p, the controller HPE specifies for that cage.

1 × Intel Xeon Gold 6548Y+ — 32 cores, 2.5 GHz, 250 W
8 × 64 GB DDR5-5600 RDIMM — 512 GB at the CPU’s 5200 MT/s
8 × 3.84 TB NVMe Gen4 U.3 SFF — 30.72 TB raw
HPE SR932i-p Gen11 8 GB wide-cache controller
NS204i-u mirrored NVMe boot
Broadcom BCM57504 4 × 25GbE SFP28 OCP 3.0
2 × 1000 W Flex Slot Titanium
VMware vSphere 8 Essentials Plus

At 250 W the 6548Y+ needs the High Performance Heatsink and seven-fan kit. The SR932i-p needs a x16 physical and electrical riser slot, and the two UMB bays are left empty in this build.

VDI & graphics

Two-A16 virtual desktop node

The GPU Dense chassis holds two double-wide NVIDIA A16 cards in its front cage without touching the risers. HPE rates two double-wide cards at 25 °C inlet and recommends system memory of at least double the total GPU memory — 256 GB for two 64 GB A16s — so this build carries 512 GB.

1 × Xeon Gold 6542Y — 24 cores @ 2.9 GHz, 250 W
2 × NVIDIA A16 64 GB (double-wide, front GPU cage)
8 × 64 GB DDR5-5600 RDIMM — 512 GB
4 × 7.68 TB 12G SAS SSD in the 4SFF Tri-Mode cage — 30.72 TB raw
HPE MR416i-p Gen11 8 GB cache PCIe controller (secondary riser)
NS204i-u mirrored NVMe boot
Intel E810-XXVDA2 2 × 25GbE SFP28 OCP 3.0
2 × 1800–2200 W Flex Slot Titanium
Windows Server 2025 Datacenter

Two double-wide GPUs need the 2 GPU FIO Enablement Kit and both 8-pin power cable kits. With that kit and the 4SFF cage HPE requires the MR416i-p (or a Gen5 retimer card) plus the 4SFF Tri-Mode cable kit; the MR416i-p sits on the secondary riser and needs a Smart Storage battery or capacitor, and the NS204i-u is limited to 25 °C ambient in this chassis.

Databases

High-clock SQL server on SAS flash

The Gold 6544Y runs 16 cores from a 3.6 GHz base clock, a fit for databases where fewer, faster cores suit the licensing. Ten SAS SSDs fill the 8SFF x1 Tri-Mode backplane and the 2SFF cage, both run by one MR416i-o; that controller is an OCP-form card and this server has a single OCP 3.0 bay, so networking moves to a PCIe card.

1 × Xeon Gold 6544Y — 16 cores @ 3.6 GHz, 270 W
8 × 32 GB DDR5-5600 RDIMM — 256 GB at the CPU’s 5200 MT/s
10 × 3.84 TB 12G SAS SSD (8 + 2 SFF) — 38.4 TB raw
HPE MR416i-o Gen11 8 GB cache OCP controller
NS204i-u mirrored NVMe boot
Broadcom BCM57414 2 × 25GbE SFP28 PCIe adapter
2 × 1000 W Flex Slot Titanium
Windows Server 2025 Standard

The 270 W 6544Y needs the High Performance Heatsink and fan kit. The 2 SFF cage in the Universal Media Bay needs its own 2SFF Tri-Mode cable kit when driven by an OCP-form controller.

12 — FAQ

DL320 Gen11 questions, answered from the documentation

What is the maximum memory of the HPE ProLiant DL320 Gen11?

HPE’s table prints 2.04 TB as 16 × 128 GB at 4800 MT/s, but the memory option lists stop at 96 GB, so the largest orderable build in this QuickSpecs is 16 × 96 GB — 1.5 TB. With all 16 slots filled, the DIMMs run at 4400 MT/s.

Which processors does the DL320 Gen11 support?

One 4th or 5th Gen Intel Xeon Scalable processor, from 8-core Bronze, Silver and Gold parts up to the 60-core Platinum 8581V at 270 W. Six Xeon 6 kits also appear in Core Options under a “(4S, 8S)” heading that conflicts with the rest of the document, so we check those with HPE before quoting.

How many drives does the DL320 Gen11 hold?

Twelve 3.5-inch drives in the 12 LFF chassis, ten 2.5-inch (8 + 2) in the SFF chassis, four 3.5-inch in the 4 LFF chassis, or eight E3.S or four SFF in the GPU Dense chassis. Every model also has two onboard M.2 sockets for boot drives.

Does the DL320 Gen11 take GPUs?

Yes, mainly in the GPU Dense chassis: up to four single-wide NVIDIA L4 or two double-wide A16, L40 or L40S cards at the front. HPE rates two L4 or one L40 or A16 at 35 °C inlet, and four L4 or two L40 or A16 at 25 °C; up to two L4 can also go in the rear slots at 25 °C.

What networking is built in?

Every CTO model has two embedded Broadcom BCM5720 1GbE ports. On top of those there is one x16 PCIe 5.0 OCP 3.0 bay and two x16 PCIe 5.0 FHHL slots for adapters from 1GbE to 100GbE, or 32Gb and 64Gb Fibre Channel.

How deep is the DL320 Gen11?

It depends on the chassis: 60.51 cm for 8 SFF, 66.47 cm for 4 LFF, 77.42 cm for GPU Dense and 99.51 cm for 12 LFF, which HPE says needs a 1200 mm deep rack. All four are 4.28 cm high and 43.46 cm wide.

Which power supplies can it use?

Up to two hot-plug Flex Slot supplies of the same model, chosen from 500 W, 800 W and 1600 W Platinum units, a 1000 W Titanium, the largest Titanium (listed as 1800–2200 W, and as 1800–2000 W in one table) and a 1600 W −48 V DC unit. The 1600 W Platinum needs 200–240 VAC, and picking the 500 W supply rules out NVMe drives in the 8 SFF chassis.

How does the DL320 Gen11 differ from the DL360 Gen11?

The DL320 is single-socket with 16 DIMM slots, two PCIe slots, one OCP bay and embedded 1GbE, and it offers 12 LFF and GPU Dense chassis. The DL360 Gen11 takes one or two processors and 32 DIMMs (8 TB), three PCIe slots and two OCP bays, has no embedded LAN, and its fronts are 4 LFF, 8+2 SFF or 20 EDSFF.

What changes on the DL320 Gen12?

HPE’s Gen12 QuickSpecs moves the DL320 to Intel Xeon 6 with up to 144 cores, DDR5-6400 memory to 4 TB, iLO 7 on a DC-SCM module, M-CRPS power supplies, front or rear OCP 3.0 and up to 20 EDSFF drives. The embedded 1GbE ports go: networking becomes an OCP card or a PCIe adapter.

Is the HPE ProLiant DL320 Gen11 end of life?

Not according to HPE’s QuickSpecs (Version 41, 3 August 2026): it names no end-of-sale or end-of-support date, and its change log retires only individual option SKUs. The warranty is HPE’s 3/3/3 — three years each of parts, labour and next-business-day on-site support — and any model dates HPE publishes later will show in our end-of-life checker.
