HP ProLiant DL360 Gen9 1U rack server 2x E5-2643v3 3.4GHz 64GB DDR4 H240ar 4 LFF

Dense 1U rack server for virtualised workloads

The HP ProLiant DL360 Gen9 fits a full two-socket Xeon platform into a single rack unit, delivering 24 hyper-threaded cores at 3.4GHz and 64GB of DDR4 ECC memory. It targets IT teams running hypervisor clusters, database nodes or high-density compute farms where rack space is at a premium. Buyers needing GPU acceleration or more than four large-form-factor drive bays should look elsewhere.

Tool-less rail kit and hot-swap components

The chassis slides into standard rails without tools and both 500W power supplies are hot-swappable, so a failed unit can be replaced without downtime. Memory population rules require balanced DIMM placement across the 24 slots per processor; incorrect ordering will halt POST. The H240ar controller must be configured in the UEFI before the OS installer sees any logical volumes.

Steady-state thermal design sustains full CPU load

Dual processors maintain 3.4GHz base frequency continuously because the 1U airflow path and redundant fans are validated for maximum TDP without throttling. The H240ar’s 12Gb SAS links keep drive queues saturated during prolonged RAID 5 or 6 rebuilds, while the embedded 331i quad-port NIC handles sustained network streams without packet loss. Power draw remains predictable under constant utilisation.
