HP ProLiant DL380 Gen9 2U rack server E5-2643 v3 6C 3.4GHz 64GB DDR4 H240ar

Server identity

The HP ProLiant DL380 Gen9 is a 2U rack server built for data-centre workloads that need dense compute and flexible storage in a standard cabinet. It ships with a single Intel Xeon E5-2643 v3 six-core processor at 3.4 GHz, 64 GB of DDR4 ECC registered memory and an H240ar controller supporting RAID 0/1/5/6/10/50/60. Eight 2.5-inch SFF drive bays are populated with trays only; no drives are included. This configuration suits virtualisation hosts, database nodes or application tiers that can scale to a second processor and up to 24 DIMM slots.

Deciding specification

The installed memory ceiling is 64 GB across 24 slots, so the system cannot accept more RAM without replacing every module. Buyers who need larger in-memory datasets or higher VM density must plan for a full memory swap rather than a simple upgrade. The single-socket layout also leaves half the memory channels and the second processor socket unused, limiting peak thread count to 12 virtual cores.

Sustained behaviour

Dual 500 W redundant hot-swap power supplies share the load, keeping the platform running if one unit fails or is replaced during operation. The Matrox G200eH2 graphics core with 16 MB video memory provides basic console output only and does not accelerate compute tasks. Under continuous load the memory runs at speeds up to 2400 MT/s dictated by the processor capability, while the H240ar maintains 12 Gb/s SAS and 6 Gb/s SATA throughput to the drive bays.
