HPE ProLiant DL340 Gen12 Parts

The HPE ProLiant DL340 Gen12 is a 2U single-socket rack server built around one Intel Xeon 6 processor — Efficient-Core parts to 144 cores or Performance-Core parts to 86 — with 16 DDR5 DIMM slots, PCIe 5.0 I/O and a three-box modular front that HPE ships as three configure-to-order chassis: 8 SFF, 12 LFF and Front GPU. Every part below is genuine HPE, available new and refurbished, and tested for compatibility before it ships. Live pricing for each part number appears in the tables further down this page.

• Drives: none shipped as standard; up to 24 SFF, 12 LFF or 36 EDSFF bays taking U.3 NVMe, 24G SAS, 12G Value SAS and 6G SATA SSDs, E3.S NVMe Gen5 SSDs, 10K SFF and 7.2K LFF hard drives to 26TB
• Storage controllers: HPE MR216i, MR408i and MR416i Gen11 in PCIe plug-in and OCP forms, the MR932i-p x32 PCIe Gen5 controller, or Intel VROC software RAID; NS204i-u v2 hot-plug boot device
• Networking: no embedded controller — rear OCP 3.0 slot A (PCIe 5.0 x16) is built in, rear OCP B and two front OCP slots are optional, and PCIe adapters run from 1Gb to 400Gb
• Expansion: slot 3 on the primary riser and slot 6 on the secondary riser, both PCIe 5.0 x16 FHHL, plus rear captive and NEBS riser options
• Power and cooling: hot-plug M-CRPS power supplies from 800W to 3200W and -48VDC options, six system fans in standard or performance kits, standard or performance heat sink
• Management: HPE iLO 7 on the DC-SCM module with a dedicated 1GbE port and front USB-C service port, four USB 3.2 Gen1 ports, embedded TPM 2.0, optional System Insight Display on the SFF chassis
• Also listed below: NVIDIA L4 and L40S accelerators, 32Gb and 64Gb Fibre Channel HBAs, optical drives, drive cages, cable kits and rail kits — each cage, cable kit and rail kit is listed against the chassis it fits

Know which of the three chassis you have before you buy anything. The DL340 Gen12 ships as an 8 SFF, a 12 LFF and a Front GPU configure-to-order server, and they do not take the same parts: the LFF chassis has no OCP 3.0 slot support and no System Insight Display, the GPU chassis takes no optical drive, and the drive cages, cable kits and rail kits are each listed against one chassis or another. Every part below is genuine HPE, tested for compatibility, with live pricing in the tables further down.

DL340 Gen12 Parts FAQ

What kind of server is the HPE ProLiant DL340 Gen12?
A 2U rack server with one Intel Xeon 6 processor socket, 16 DDR5 DIMM slots and PCIe 5.0, offered as three configure-to-order chassis: 8 SFF, 12 LFF and Front GPU. HPE positions it as a 2U single-socket performance server for IaaS, PaaS and SaaS workloads.

How many processors does the DL340 Gen12 take?
One. The kits listed here cover Intel Xeon 6 Efficient-Core parts from 64 to 144 cores and Performance-Core, Mainline and Single Socket RICH I/O parts from 8 to 86 cores, at 150W to 350W. The single-socket 6XX1P processors provide 136 PCIe lanes.

How much memory does the DL340 Gen12 support?
Up to 4TB, using sixteen 256GB DDR5 3DS RDIMMs. The server has 16 DIMM slots across 8 channels, runs 6400 MT/s with one DIMM per channel and 5200 MT/s with two, and takes HPE DDR5 Smart Memory Registered DIMMs only.

How many drives fit in a DL340 Gen12?
Up to 24 SFF drives or 36 EDSFF drives in the SFF chassis, 12 LFF drives in the LFF chassis, and an optional 8 SFF or 12 EDSFF cage in the Front GPU chassis. No drives ship as standard; every bay is filled from the drives listed here.

Does the DL340 Gen12 have built-in networking?
No. HPE fits no default network controller. A rear OCP 3.0 slot A is embedded, a rear OCP B slot and two front OCP 3.0 slots are optional, and PCIe stand-up adapters are listed from 1Gb to 400Gb, so every build needs at least one adapter.

Which power supplies does the DL340 Gen12 use?
Hot-plug M-CRPS kits: 800W Platinum, 1000W, 1500W, 2400W and 3200W Titanium, and 1300W and 2200W -48VDC units with matching power cords and lug kits. HPE does not allow mixing power supplies in one server.
