HPE ProLiant DL385 Gen11 2U server

This 2U rack server ships with one AMD EPYC 9004 Series 9124 processor running at 3.0 GHz with 16 cores and 32GB of memory installed. The platform supports SATA, SAS and NVMe drives in hot-swap 2.5 inch bays and includes a Broadcom BCM5719 Gigabit Ethernet controller. It is built for AI, ML and HPC workloads in a two-way scalable chassis.

Suited for AI and HPC clusters needing density

Organisations deploying dense compute for model training or scientific simulation will benefit from the two-processor ceiling and 24 memory slots. Buyers who need more storage bays than the 2.5 inch hot-swap layout provides should evaluate alternative chassis designs. Teams requiring higher single-thread clock speeds or integrated graphics must look at different processor families.

Single AMD EPYC 9124 processor installed

The server arrives with one 16-core EPYC 9124 CPU and supports a second processor to reach the two-way maximum. This socket count decision determines whether the system meets the parallel throughput target for the intended workload. Verify the second-processor upgrade path before ordering if the application scales beyond 16 cores.

Questions about this item

Will the HPE MR408i-o Gen11 SPDM controller need a firmware update or battery replacement later?

The HPE MR408i-o Gen11 SPDM controller manages SATA, SAS and NVMe drives; firmware updates are applied through HPE tools and the unit has no user-replaceable battery.

What limits the EPYC 9124 16-core processor during sustained full-load operation?

The single installed EPYC 9124 16-core processor at 3.0 GHz sets the compute ceiling; a second socket can be added to double thread count.

How much power does the 2U chassis draw and how loud are the fans when the server runs 24 hours a day?

The 2U rack chassis uses redundant hot-plug power supplies and variable-speed fans that ramp with inlet temperature and CPU load.
