DL345 Gen11 Parts FAQ

Is the HPE ProLiant DL345 Gen11 a single-processor server?
Yes. The QuickSpecs describe it as a 2U 1P solution and instruct you to select one 4th or 5th Generation AMD EPYC processor. That one CPU provides all 12 memory channels and 128 PCIe 5.0 lanes.

How much memory does the DL345 Gen11 support?
Up to 3.0TB. The server has 12 DIMM slots on 12 channels at 1 DIMM per channel, and the QuickSpecs give the maximum as 12 x 256GB RDIMM - at 4800 MT/s with 4th Gen EPYC processors and 6400 MT/s with 5th Gen.

How many drives fit in a DL345 Gen11?
Up to 34 SFF drives, 20 LFF drives, or 36 EDSFF E3.S 1T drives, depending on the chassis. The CTO chassis choices are 8SFF, 24SFF, 8LFF, EDSFF, and GPU.

Does the DL345 Gen11 have built-in network ports?
No. The QuickSpecs list network ports as none and state 'No embedded networking' - every build selects either an OCP 3.0 card or a stand-up PCIe adapter for primary networking. The dedicated 1Gb iLO management port is separate.

How many PCIe slots does the DL345 Gen11 have?
Two PCIe 5.0 x16 slots by default, one on each riser. The 4PCIe enablement kit takes it to four slots and the 6PCIe enablement kit to six. The GPU CTO server adds front slots for up to four single-width or two double-width GPUs.

Can I mix new and refurbished parts in the DL345 Gen11?
Yes. Genuine HPE parts perform identically whether new or refurbished, and refurbished stock is tested before shipping - a common way to add memory, drives, or a second power supply at lower cost.
