HPE ProLiant DL345 Gen11Specifications, configurations & comparisons

The DL345 Gen11 pairs a single AMD EPYC socket with a full 2U of drive space: front, mid-tray and rear cages take it to 34 SFF, 20 LFF or 36 E3.S bays. This sheet maps its 40 processors, the 12-DIMM memory rules, the five configure-to-order chassis and the cooling and cage restrictions that decide which options can be combined.

01 — Overview

The DL345 Gen11 at a glance

Our read of HPE’s documentation: where the DL345 Gen11 is strong, and the limits worth knowing before you spec one.

Strengths

A 2U drive envelope behind one processor: 34 SFF, 20 LFF or 36 E3.S bays, because HPE adds mid-tray and rear cages to the front drive boxes.
Both EPYC generations on one board: 21 EPYC 9005 and 19 EPYC 9004 SKUs spanning 8 to 160 cores, with the X-series 9684X carrying 1,150 MB of L3 for cache-hungry code.
Up to 32 NVMe drives cabled straight to the processor in the 8SFF chassis (24 front plus 8 mid-tray), with no RAID controller in the data path.
Six full-height PCIe 5.0 x16 slots and two OCP 3.0 slots from the one socket’s 128 lanes, plus a dedicated GPU chassis with four front slots.

Watch-outs

Memory stops at 12 DIMMs. The 3 TB ceiling needs 256 GB 3DS modules, which the option list places only in the 5th Gen group and which rule out every mid-tray cage.
A mid-tray cage limits the processor to 300 W and forces the 1U Performance Heat Sink and the Performance Fan Kit.
The overview promises two double-width GPUs, yet the accelerator list in this revision offers only the single-width NVIDIA L4.
The 4LFF rear cage is factory-installed only and rules out both slot enablement kits: its riser options stop at two x16 positions (slots 3 and 6), and with an NS204i-u fitted the boot device moves to slot 6 on the low-profile riser.
Slot pairs share a 112 GB/s ceiling set by the processor, so the six-slot layout is not six independent full-speed links.

Wattages are default cTDP. Up to 240 W HPE specifies the Standard Heat Sink with the Standard Fan Kit. For 260 W and above, one processor note names only the Performance Heat Sink while the cooling-option notes pair it with the Performance Fan Kit; the cooling summary, which splits at 240 W rather than 260 W, keeps Standard fans for a front-only chassis and switches to Performance fans once a mid-tray or rear cage or the GPU chassis is chosen.
Any 4LFF or 8SFF mid-tray cage caps the processor at 300 W and requires the 1U Performance Heat Sink with the Performance Fan Kit.
The EPYC 9734 (112 cores, 340 W) appears in the 4th Gen standard-features table but has no option kit in the processor order list.
The EPYC 9255 base clock differs between tables: 3.25 GHz in standard features, 3.20 GHz in its option-kit name.
Every 5th Gen part is listed with 6400 MT/s memory and every 4th Gen part with 4800 MT/s.

03 — Memory

12 DDR5 DIMM slots

Twelve DDR5 RDIMM slots, one on each of the processor’s 12 channels, with no second DIMM per channel to add later. HPE allows 1, 2, 4, 6, 8, 10 or 12 modules, and the processor generation fixes the speed: DDR5-6400 kits for EPYC 9005, DDR5-4800 kits for EPYC 9004.

by DIMM size

Rated memory speed

from the processor table

Processor family	Up to
AMD EPYC 9005	6400 MT/s
AMD EPYC 9004	4800 MT/s

Standard features quote 3.0 TB for both generations, including 12 × 256 GB at 4800 MT/s for 4th Gen. The memory order list, however, carries the 256 GB 3DS kit only in the DDR5-6400 (5th Gen) group; its largest DDR5-4800 kit is 128 GB, which gives 1.5 TB (12 × 128 GB).
Selecting 256 GB modules rules out the 4LFF and both 8SFF mid-tray cages; HPE’s cooling table allows them only with a front-only layout and the Performance Fan Kit.
x4 and x8 modules cannot share a server, nor can 3DS and non-3DS parts; if speeds are mixed, every DIMM drops to the slowest one.
No LRDIMM or persistent memory. Protection is Advanced ECC plus Online Spare rank sparing.

04 — Storage

18 drive-cage kits, up to 36 bays

HPE sells the DL345 Gen11 as five configure-to-order chassis — 8LFF, 8SFF, 24SFF, EDSFF and GPU — and each accepts a different set of front, mid-tray and rear cages. The headline layouts below are complete builds taken from HPE’s supported-storage tables; the chart after them plots the individual cage kits.

SFF NVMe is U.3 only: HPE marks U.2 drives unsupported on every SFF cage, and all LFF cages are SAS/SATA.
The overview says the 8SFF chassis also reaches 34 SFF, but its 8SFF storage table stops at 32 drives; the 34-drive rows sit under the 24SFF chassis.
The 8SFF x1 and x4 cage kits cannot be mixed, and only one 2SFF cage — the front/rear stackable kit or the side-by-side kit for the 8LFF chassis — can be ordered.
HPE’s kit descriptions and its EDSFF table disagree on which part number is the 36-bay cage and which the 20-bay (P55090-B21 and P64383-B21). In the 20-bay x4 cage, bays 9–12 of box 2 stay empty because of PCIe lane limits.
The NS204i-u boot device (two 480 GB M.2 NVMe drives in RAID 1, hot-plug) sits above power supply 2, or in slot 6 on a low-profile riser when the 4LFF rear cage is fitted.
Pick one controller family per server: HPE does not allow MR-series (MegaRAID) cards alongside SR-series (SmartRAID) cards.
Two capacity figures in the maximum-storage table do not match the rest of the document: 552.96 TB is printed against 34 × 15.36 TB E3.S drives (34 × 15.36 TB is 522.24 TB; 552.96 TB matches 36), and 480 TB is printed for 20 × 24 TB LFF drives, while this revision’s LFF drive list stops at 20 TB.

05 — Accelerators & I/O

GPUs, PCIe and networking

Accelerators go only in the GPU configure-to-order chassis, which adds four full-height, full-length PCIe 5.0 x16 slots at the front (9, 11, 14 and 16) and limits front storage to 12 EDSFF or 8 SFF bays. HPE’s overview allows four single-width or two double-width cards, but the accelerator list in this revision holds one part: the NVIDIA L4, a single-width PCIe Gen4 x16 card. Up to 4 × single-width NVIDIA L4 in the GPU chassis (front slots enabled by the 2- or 4-GPU kit).

I/O topology

128 lanes per CPU

One SP5 socket supplies 128 PCIe 5.0 lanes. Two FHHL x16 slots (3 and 6) come as standard; the 4-slot kit adds slots 1 and 2 on the primary riser, the 6-slot kit adds slots 1, 2, 4 and 5, and the GPU chassis adds its four front slots.

HPE caps these pairs at 112 GB/s combined because of the processor: slot 1 with OCP slot 21 or 22, slots 2 and 3, slot 4 with OCP 22, slots 5 and 6, and in the GPU chassis slot 9 with OCP 22 and slot 16 with OCP 21.
Only one enablement kit can be fitted, and neither works with the 4LFF rear cage, which instead needs two primary FIO risers or a primary riser plus the low-profile riser and an NS204i-u.
The OCP1 upgrade cable (P56658-B21) takes OCP slot 21 to x16; HPE requires it for its OCP InfiniBand adapters, the Broadcom BCM57504 4-port and the Intel E810 100GbE OCP adapter.
100/200 GbE and InfiniBand adapters require the Performance Fan Kit.
There is no embedded LAN: every port comes from an OCP 3.0 or stand-up adapter.

06 — Power & cooling

6 power supplies, 500–2,200 W

The DL345 Gen11 runs on one or two HPE Flex Slot hot-plug supplies, and a pair must be the same model. The range starts at a 500 W Platinum unit and ends at a Titanium unit badged 1800–2200 W; in between sit 800 W Platinum, 1000 W Titanium and 1600 W Platinum AC models and a 1600 W supply for −48 V DC rooms.

AC−48 V DC

The 1600 W Platinum supply runs on high-line 200–240 V AC only.
The −48 V DC supply needs lug kit P36877-B21. Its standard-features entry also says “200-240VAC power input only”, which contradicts the DC rating in its name.
HPE’s ErP Lot 9 paragraph names the 1000 W (P03178-B21) and 1800–2200 W (P44712-B21) units as 96% efficient; the third part it names, 865438-B21, is not offered for this server.
HPE prints BTU and output tables for just three of the six supplies (500, 800 and 1600 W); the two smaller ones keep their full rated output on a 100 V feed too.

09 — Use cases

Five builds that suit the DL345 Gen11

Five storage-leaning DL345 Gen11 builds, every part drawn from this server’s options in our configurator. Each one opens ready to edit, and the cage, cabling and cooling choices are re-checked against HPE’s tables at quotation.

Software-defined storage

24-bay NVMe object or Ceph node

HPE pitches this server at software-defined storage, and its 8SFF chassis can cable 24 U.3 NVMe drives straight to the processor, so the storage software sees raw devices with no RAID layer. A 48-core 9455P leaves room for erasure coding, and a 100GbE card in a rear slot carries replication traffic.

1 × AMD EPYC 9455P — 48 cores @ 3.15 GHz, 300 W
12 × 64 GB DDR5-6400 RDIMM — 768 GB, every channel filled
24 × 7.68 TB NVMe U.3 across the 24 SFF front bays — 184.32 TB raw
NS204i-u boot: 2 × 480 GB M.2 NVMe in RAID 1
Broadcom BCM57608 2 × 100GbE QSFP112 PCIe adapter
2 × 1600 W Flex Slot Platinum (200–240 V only)
Red Hat Enterprise Linux 9, 3-year subscription

The configurator link opens this as one 24-bay SFF cage with two supplies. HPE’s own table builds 24-drive NVMe direct attach differently: the 8SFF chassis with three 8SFF x4 U.3 cages, at x2 per drive on cable kit P57126-B21 or at x4 with P57125-B21 and two OCP retimers, so we set the chassis and cabling at quotation. The 300 W processor needs the Performance Heat Sink, and the 100GbE adapter the Performance Fan Kit.

Backup repository

20-bay LFF backup target

Filling the 8LFF chassis in all three zones — 12 front, 4 mid-tray and 4 rear — gives 20 LFF bays, a layout HPE’s storage table runs from one 32-lane SR932i-p. Twenty 8 TB SAS drives make 160 TB raw; HPE’s current LFF list goes up to 20 TB per drive. A 16-core 200 W processor is plenty for a repository and stays under the 300 W ceiling for the mid tray.

1 × AMD EPYC 9135 — 16 cores @ 3.65 GHz, 200 W
20 × 8 TB 7.2K SAS LFF HDD — 160 TB raw
12 front + 4 mid-tray + 4 rear LFF bays
HPE SR932i-p Gen11 32-lane controller, 8 GB cache
12 × 32 GB DDR5-6400 RDIMM — 384 GB
NS204i-u mirrored M.2 boot
Broadcom BCM57504 4 × 25GbE SFP28 OCP 3.0
2 × 1000 W Flex Slot Titanium
Windows Server 2025 Standard

The mid-tray cage needs the 1U Performance Heat Sink and Performance Fan Kit and rules out 256 GB DIMMs. The rear cage is factory-installed only, blocks the 4- and 6-slot kits and moves the NS204i-u to slot 6 on a low-profile riser. HPE pairs the SR932i-p with an energy pack (96 W battery or hybrid capacitor), and the 4-port OCP card with the OCP1 upgrade cable.

Analytics & transcoding

36-drive E3.S flash node

HPE lists video transcoding among the data-intensive jobs it targets. The EDSFF chassis puts 36 E3.S drives on the processor’s own lanes with no controller, and the 64-core 9575F pairs a 3.3 GHz base with the 5 GHz peak shared only by the 9175F in HPE’s tables.

1 × AMD EPYC 9575F — 64 cores @ 3.3 GHz, 400 W
36 × 7.68 TB E3.S NVMe — 276.48 TB raw
EDSFF chassis, 36-bay cage at x2 direct attach
12 × 96 GB DDR5-6400 RDIMM — 1,152 GB
NS204i-u mirrored M.2 boot
Broadcom BCM57608 2 × 100GbE QSFP112 OCP 3.0
2 × 1800–2200 W Flex Slot Titanium
SUSE Linux Enterprise Server 15

The 36-bay cage is factory-installed only, and HPE’s kit list and EDSFF table swap its part number with the 20-bay cage’s, so we confirm the kit when quoting. The 400 W processor needs the Performance Heat Sink and the 100GbE adapter the Performance Fan Kit.

Virtualisation

160-core, 3 TB consolidation host

One EPYC 9845 brings 160 cores, and twelve 256 GB 3DS modules fill every channel to the 3 TB ceiling on a single socket. The front is the 24SFF chassis, one of the layouts HPE’s 256 GB cooling table permits, with eight U.3 NVMe drives behind the SR932i-p that HPE’s 24SFF table lists for all 24 tri-mode bays, so sixteen bays stay free.

1 × AMD EPYC 9845 — 160 cores @ 2.1 GHz, 390 W
12 × 256 GB DDR5-6400 3DS RDIMM — 3 TB
8 × 7.68 TB NVMe U.3 in the 24SFF chassis — 61.44 TB raw
HPE SR932i-p Gen11 32-lane controller, 8 GB wide cache
NS204i-u mirrored M.2 boot
Broadcom BCM57504 4 × 25GbE SFP28 OCP 3.0
2 × 1600 W Flex Slot Platinum (200–240 V only)
Windows Server 2025 Datacenter

256 GB modules exclude every mid-tray cage, need the Performance Fan Kit and cannot be mixed with non-3DS DIMMs. The 390 W processor needs the Performance Heat Sink, the SR932i-p a 96 W battery or hybrid capacitor, and the 4-port OCP card the OCP1 upgrade cable for x16.

AI inference & video

Four-L4 GPU chassis

The GPU chassis moves four full-length PCIe 5.0 x16 slots to the front while keeping 12 EDSFF bays. The NVIDIA L4 is the accelerator HPE currently lists for it; four of these single-width cards give 96 GB of GPU memory for inference or video work.

1 × AMD EPYC 9355P — 32 cores @ 3.55 GHz, 280 W
4 × NVIDIA L4 24 GB, single-width, front slots
12 × 64 GB DDR5-6400 RDIMM — 768 GB
8 × 7.68 TB E3.S NVMe in the 12-bay GPU-chassis cage
NS204i-u mirrored M.2 boot
Broadcom BCM57608 2 × 100GbE QSFP112 OCP 3.0
2 × 1600 W Flex Slot Platinum
Red Hat Enterprise Linux 9

The L4 can only be ordered with the GPU chassis, which needs the factory-installed 4-GPU front enablement kit and the Performance Fan Kit; its 12-EDSFF cage needs signal cable kit P64381-B21. The chassis is 79.87 cm deep, its only rail option is the Ball Bearing Rail 8 Kit, and the front extension slots do not support external cabling.

12 — FAQ

DL345 Gen11 questions, answered from the documentation

What is the maximum memory of the HPE ProLiant DL345 Gen11?

3 TB, from twelve 256 GB 3DS RDIMMs — one per memory channel, as there is no second DIMM per channel. The 256 GB kit sits in the DDR5-6400 list for 5th Gen EPYC; although standard features also quote 12 × 256 GB at 4800 MT/s for 4th Gen, the largest DDR5-4800 kit HPE lists is 128 GB, which gives 1.5 TB.

Which processors does the DL345 Gen11 support?

HPE’s tables list 40 single AMD EPYC processors: 21 from the 5th Gen 9005 family and 19 from the 4th Gen 9004 family, with 8 to 160 cores and default cTDPs of 125–400 W. The 160-core 9845 has the most cores and the 9684X the largest cache at 1,150 MB; the 9734 appears in the table without an orderable option kit.

How many drives can the DL345 Gen11 hold?

Up to 34 SFF drives (24 front, 8 on a mid tray, 2 at the rear), 20 LFF drives (12 front, 4 mid-tray, 4 rear) or 36 EDSFF E3.S drives, depending on which of the five CTO chassis you start from. Up to 32 of the SFF bays can run NVMe direct-attached to the processor, and the NS204i-u boot device comes on top.

How many GPUs does the DL345 Gen11 support?

HPE’s overview allows four single-width or two double-width GPUs, all in the front slots of the GPU chassis. In this QuickSpecs revision the only accelerator offered is the NVIDIA L4 24 GB, a single-width PCIe Gen4 card, so four L4s is the orderable maximum. Obsolete NVIDIA accelerator SKUs were removed in earlier revisions.

How many PCIe slots does the DL345 Gen11 have?

Two PCIe 5.0 x16 full-height, half-length slots as standard, rising to four or six with HPE’s enablement kits, plus two OCP 3.0 slots at x8. The GPU chassis adds four full-length x16 slots at the front. The processor provides 128 PCIe 5.0 lanes, and several slot pairs share a 112 GB/s limit.

What power supplies are available for the DL345 Gen11?

Six hot-plug Flex Slot models are listed, from a 500 W Platinum unit up to the 1800–2200 W Titanium, with a 1600 W −48 V DC option for telco power. A server holds one or two supplies and HPE does not allow two different models together. The 1600 W Platinum model needs a 200–240 V feed.

How big and heavy is the DL345 Gen11?

Height and width stay the same across the five chassis — 8.75 cm by 44.8 cm — but depth varies: 64.6 cm for 8SFF, 24SFF and EDSFF, 66.3 cm for 8LFF and 79.87 cm for the GPU version. HPE’s approximate weights run from 16.04 kg for a minimal 8SFF server to 27.12 kg for a GPU chassis with two double-width accelerators and 12 EDSFF drives.

How does the DL345 Gen11 differ from the DL345 Gen12?

The Gen12 takes only 5th Gen EPYC, up to 192 cores and 500 W, and has 24 DIMM slots at two per channel for 6 TB, at a two-per-channel speed its QuickSpecs gives as 4000 MT/s in the capacity table and 4400 MT/s in two notes. It moves to iLO 7 and M-CRPS supplies up to 3200 W, offers three CTO chassis with up to 24 SFF, 12 LFF or 36 E3.S bays plus a rear 2SFF cage, and lists double-width GPUs such as the RTX PRO 6000.

How does the DL345 Gen11 compare with the DL365 Gen11?

The DL365 Gen11 is a 1U server for one or two EPYC processors, with 12 DIMM slots per processor (24 when both are fitted), up to 10 SFF or 20 EDSFF drives and two front GPUs. The DL345 Gen11 stays at one processor and 12 DIMMs but uses its 2U height for up to 34 SFF, 20 LFF or 36 E3.S drives and six PCIe slots.

Is the HPE ProLiant DL345 Gen11 end of life?

Not according to HPE’s own document: version 40 of the DL345 Gen11 QuickSpecs, dated 3 August 2026, is still adding and retiring options, and it publishes no end-of-sale or end-of-support date for the model. Warranty is three years of parts, labour and next-business-day onsite cover, and HPE lists 3- and 5-year Tech Care Essential services for this model. Should HPE announce support-end dates, we add them to our end-of-life checker.
