HPE ProLiant DL560 Gen11Specifications, configurations & comparisons

The ProLiant DL560 Gen11 packs four 4th Gen Xeon Scalable processors, 64 DDR5 slots and up to 24 drives into 2U. Its QuickSpecs read as a set of trade-offs rather than one specification: the air- or liquid-cooled chassis chosen at order decides which processors a four-socket build can use, and HPE’s thermal tables cap the inlet temperature for each mix of drives, DIMMs and cards.

01 — Overview

The DL560 Gen11 at a glance

Our read of HPE’s documentation: where the DL560 Gen11 is strong, and the limits worth knowing before you spec one.

Strengths

240 cores from four 60-core Platinum 8490H processors, with sixteen DIMM slots per socket, in a 2U chassis.
Up to 24 front SFF drives on tri-mode or NVMe cages, or 24 E3.S NVMe drives in a four-socket build, with a front media bay option in Box 1.
Two processors can run on their own: HPE lists a 2P air baffle and a UPI pass-through kit, and all nine processors are supported in the two-socket air-cooled build.
Five Flex Slot supplies — four AC units from an 800 W Platinum on 100–240 VAC to the 1800–2200 W Titanium, and one −48 VDC model — in 1+1, 2+2 or 3+1 redundancy.
Two risers of x8/x16/x8 or x16/x16/x16 give six full-height PCIe 5.0 slots, with two OCP 3.0 slots beside them.

Watch-outs

Only nine processors are listed, all 4th Gen H-series; the QuickSpecs offer no 5th Gen Xeon Scalable or Xeon 6 option.
Cooling is fixed at order and cannot be converted later: four-socket builds of the 6434H, 8444H, 8460H, 8468H and 8490H need the liquid-cooled chassis, leaving the 6416H, 6418H, 6448H and 8450H for four-socket air cooling.
The 16 TB ceiling depends on a 256 GB DIMM that appears only in HPE’s support matrix; the largest kit in the ordering lists is 128 GB, which makes 8 TB across 64 slots.
Thermal tables set the maximum inlet by processor, storage, DIMM size and network card — down to 20 °C for some four-socket builds — and many of HPE’s adapter tables allow 24 SFF drives on four air-cooled sockets only with the 6416H or 6418H.
The liquid-cooling heat sink kit is factory-fit only, has no leak detection and carries a five-year maximum usage limit, after which HPE requires its replacement.

02 — Processors

9 supported processors, mapped

HPE lists nine processors, all 4th Gen Xeon Scalable H-series: five Platinum (8490H, 8468H, 8460H, 8450H, 8444H) and four Gold (6448H, 6434H, 6418H, 6416H), from 8 to 60 cores and 165 W to 350 W. A server runs two or four of the same model, and whether a four-socket build can use a given part depends on the cooling chosen at order.

Intel Xeon-Gold 6434H	8	3.7 GHz	22.5 MB	195 W	24.4	DDR5-4800

In two-socket builds all nine processors are air-cooled; in four-socket builds the 6416H, 6418H, 6448H and 8450H are air-cooled and the 6434H, 8444H, 8460H, 8468H and 8490H need the Liquid Cooling CTO (P55182-B21).
UPI runs at 16 GT/s over four links in a two-socket build and three links in a four-socket build.
A two-socket server must be ordered with the 2P air baffle (P55550-B21) and the 2P UPI pass-through kit (P54806-B21); a 4P CPU mezzanine kit (P54803-B21) also appears among the key options.
Heat sinks: P48818-B21 for two-socket air cooling, P48905-B21 for four-socket air cooling, and the factory-fitted P54791-B21 kit for four-socket liquid cooling.
HPE notes that maximum memory per processor depends on the processor model and the storage layout, which its support matrix sets out.

03 — Memory

64 DIMM slots, 16 per processor

Each of the four processors has eight DDR5 channels with two slots apiece — 16 per socket and 64 in all. HPE rates the DDR5-4800 kits for 4800 MT/s at one DIMM per channel, falling to 4400 MT/s when a channel carries two. Its 16.0 TB maximum (64 × 256 GB) is printed at 4800 MT/s, although 64 DIMMs means two per channel, where the same document gives 4400 MT/s.

per HPE memory tables

Processor	1 DIMM / channel	2 DIMMs / channel
4th Gen Xeon Scalable (H-series)	4800 MT/s	4400 MT/s

Per processor, HPE’s population table runs through 1, 2, 4, 6, 8, 12 or 16 modules — other counts lack Intel qualification — and the ordering notes ask for an even number of DIMMs.
The ordering lists offer 16, 32, 64, 96 and 128 GB RDIMMs; the 256 GB part (P43337-B21) and a second 128 GB part (P43334-B21) are named only as support-matrix columns.
On the liquid-cooled CTO, a 128 GB configuration has to use the quad-rank P63345-B21 module.
96 GB modules go in at half or full population on every processor and cannot be mixed with other sizes.
HPE’s CPU/storage/memory support matrix lowers the maximum inlet temperature as DIMM size and drive count rise, reaching 20 °C in some four-socket rows.

04 — Storage

4 drive-cage kits, up to 24 bays

The front has three drive boxes. The base 8 SFF chassis grows to 24 SFF with tri-mode x1 or NVMe x4 cages, or takes 12-bay EDSFF cages — up to 16 E3.S drives with two processors and 24 with four. Boxes fill in a set order: Box 3 first on two-socket systems, Box 2 first on four-socket ones, with Box 1 last.

Headline layouts

Front panel

Three 8SFF U.3 cages across Boxes 1–3; x1 tri-mode and x4 NVMe cages cannot be mixed. On four air-cooled sockets many adapter tables allow it only with the 6416H or 6418H (the DIMM matrix also shows a 20 °C row for the 250 W parts), and the adapter tables mark it not supported on the liquid-cooled model.

Direct-attached and tri-mode-controlled drives cannot be mixed, and HPE’s tri-mode controllers do not support PE80xx NVMe drives.
The NS204i-u boot device mounts at the front between the fan cage and the drive boxes (not hot-pluggable) or at the rear in slot 4 of the second riser (hot-pluggable); a front boot device on a liquid-cooled server rules out the media bay.
A drive-less build still needs an x4 cage and a direct-attach cable, with no controller.
HPE’s maximum-storage table gives 368.64 TB for 24 × 15.36 TB SAS or NVMe SSDs and 57.6 TB for 24 × 2.4 TB SAS hard drives.

GPU support is narrow. Double-wide cards can only sit in slot 2 of the primary riser and slot 5 of the secondary, at up to 10.5 inches long, with the GPU Enablement Kit (P54816-B21). The NVIDIA L40 48 GB is the one accelerator with an option part number; HPE’s thermal table allows it at up to 30 °C with a single drive box, 30 °C or less with two, and not at all with 24 SFF drives or on the liquid-cooled four-socket model. A second table is headed H100 80GB but carries no option part, and the change log records a graphics-accelerator SKU removed in version 22.

On the x16/x16/x16 riser the first slot is cabled — to processors 1 or 2 in a two-socket server, 3 or 4 in a four-socket one — through a motherboard or mezzanine cable kit. Two OCP 3.0 slots sit alongside, and there is no embedded LAN.

With one riser the factory fits it in the primary position; with two, the x16/x16/x16 riser goes in the primary position.
x16 cards fitted in x8 slots may see reduced performance.
OCP at x16 needs the OCP x16 to Motherboard Enablement Kit (P55322-B21) on two-socket builds or the Mezzanine Board kit (P55324-B21) on four-socket builds.
Some network adapters must go in riser 1 or in OCP2, and each carries its own inlet limits in HPE’s adapter tables.
Rear ports are VGA, two USB 3.2, the 1 Gb iLO port and an optional serial port (cable kit P48824-B21); the media bay’s front DisplayPort and the rear VGA cannot be active together.

06 — Power & cooling

5 power supplies, 800–2,200 W

Two to four HPE Flex Slot hot-plug supplies, all the same model, in 1+1, 2+2 or 3+1 redundancy. Low-line and high-line sites can both use the 800 W Platinum and 1000 W Titanium units; the 1600 W Platinum and the Titanium unit rated 1800–2200 W are high-line only, and a 1600 W −48 VDC unit covers DC sites.

AC−48 V DC

HPE lists a 4x Power Supply Enablement Kit (P54812-B21) among the key options.
The −48 VDC unit is sold as 1600 W, but the technical specifications print its rated output as 800 W at −40 and −72 VDC.
The 1000 W and 1800–2200 W Titanium units (P03178-B21, P44712-B21) are among the part numbers HPE cites as 96% efficient for EU ErP Lot 9, which covers units sold into the UK.
The 1800–2200 W Titanium supply is capped at 1600 W in Gen10 and Gen10 Plus servers; output above 1600 W needs a Gen11 server such as this one.
Fans: six high-performance fans on the Air Cooling CTO (P55181-B21), five performance fans on the Liquid Cooling CTO (P55182-B21).
In HPE’s acoustic declaration the entry configuration measured 5.6 B operating and the performance configuration 6.1 B.

HPE’s L40 table allows 30 °C inlet with one EDSFF box on a two-socket air-cooled server and 25 °C with two; the card is not supported on the liquid-cooled four-socket model. Each GPU needs a riser in its position.

Database & storage-heavy

24-SFF four-socket database server

Filling all three boxes gives 24 SFF bays for database files and logs. Many of HPE’s adapter tables allow that on four air-cooled sockets only with the 165 W 6416H or the 185 W 6418H, so this build uses four 24-core 6418H processors (96 cores), an SR932i-p controller and 32 × 64 GB of memory.

4 × Xeon-Gold 6418H — 24 cores @ 2.1 GHz, 185 W each
32 × 64 GB DDR5-4800 RDIMM — 2 TB, one per channel
8 × 7.68 TB SAS SSD in one tri-mode cage — two more cages and 16 more drives set on the quote for 24
HPE SR932i-p Gen11 tri-mode controller, 8 GB wide cache, in an x16 riser slot
NS204i-u NVMe boot device
Broadcom BCM57414 2 × 10/25 GbE SFP28 OCP3
2 × 1600 W Flex Slot Platinum (200–240 VAC)
Air Cooling CTO (P55181-B21)
Windows Server 2025 Standard
HPE Tech Care Basic

On four air-cooled sockets HPE’s adapter tables give this layout 20–30 °C or no support, depending on the card, while the DIMM matrix lists 35 °C for it with 64 GB modules on the 6416H and 6418H; the adapter tables mark it not supported on the liquid-cooled model. Cached controllers need a battery or hybrid capacitor.

10 — Refurbished alternatives

When a refurbished ProLiant makes more sense

None of the refurbished ProLiant models we configure has four sockets. Where two sockets and DDR4 are enough — a consolidation or database host that does not need 64 DIMM slots — these earlier 2U servers are the refurbished options.

12 — FAQ

DL560 Gen11 questions, answered from the documentation

What is the maximum memory of the HPE ProLiant DL560 Gen11?

HPE quotes 16.0 TB from 64 × 256 GB RDIMMs. That 256 GB module appears only in the support matrix, not in the ordering lists, whose largest kit is 128 GB — 8 TB across the 64 slots. A second DIMM on a channel brings the speed down from 4800 MT/s to 4400 MT/s.

How many processors does the DL560 Gen11 take?

Two or four of the same model, chosen from nine 4th Gen Xeon Scalable H-series parts of 8 to 60 cores. With four processors, the 6416H, 6418H, 6448H and 8450H can be air-cooled, while the 6434H, 8444H, 8460H, 8468H and 8490H need the liquid-cooled chassis.

Can the DL560 Gen11 run with only two processors?

Yes. Two-socket builds use the 2P air baffle and UPI pass-through kits, run all nine processors air-cooled over four UPI links, and populate the 32 DIMM slots belonging to those two processors. They are limited to 16 E3.S drives, against 24 with four sockets.

How many drives does the DL560 Gen11 hold?

Up to 24 SFF drives in three 8-bay boxes, or up to 24 E3.S NVMe drives with four processors (16 with two). A Universal Media Bay in Box 1 adds two SFF or NVMe drives and front ports. On four air-cooled sockets, many of HPE’s adapter tables allow 24 SFF only with the 6416H or 6418H.

Does the DL560 Gen11 support GPUs?

Two double-wide cards can go in slots 2 and 5 with the GPU Enablement Kit, at up to 10.5 inches long. The NVIDIA L40 48 GB is the only accelerator with an option number, and HPE’s thermal table rules it out of liquid-cooled four-socket and 24-SFF builds.

How many PCIe slots does the DL560 Gen11 have?

Up to six PCIe 5.0 full-height slots on two risers, each x8/x16/x8 or x16/x16/x16, with a pair of OCP 3.0 slots alongside. No network port is built in, so every order includes an OCP or PCIe adapter.

Which power supplies does the DL560 Gen11 use?

Two to four matching Flex Slot supplies in 1+1, 2+2 or 3+1 redundancy: 800 W Platinum or 1000 W Titanium on 100–240 VAC, 1600 W Platinum or 1800–2200 W Titanium on 200–240 VAC, or a 1600 W −48 VDC unit.

How big and heavy is the DL560 Gen11?

The SFF chassis measures 8.75 × 43.3 × 80.6 cm. HPE gives 21.08 to 38.02 kg for air-cooled builds and 26.83 to 36.93 kg for liquid-cooled builds.

How does the DL560 Gen11 compare with the DL580 Gen12?

Going by the two QuickSpecs, the DL580 Gen12 is a 4U server for Intel Xeon 6 P-core processors, field-upgradeable from two to four sockets, with 64 slots for 16 TB (6400 MT/s at one DIMM per channel, 5200 MT/s at two), up to 32 SFF or EDSFF drives and iLO 7. The DL560 Gen11 fits four 4th Gen H-series processors in 2U with DDR5-4800, 24 front bays and iLO 6.

Is the HPE ProLiant DL560 Gen11 end of life?

Version 33 of the QuickSpecs (3 August 2026) sets no end-of-sale or end-of-support date. What its change log removes are options — SSD families, InfiniBand adapters and tape drives. Our end-of-life checker will show dates if HPE announces them.
