HP ProLiant DL380 Gen9 2U rack server E5-2643 v3 6C 3.4GHz 64GB DDR4 2x 146GB SAS P440 4GB FBWC

2U rack server with dual Xeon headroom

The HP ProLiant DL380 Gen9 occupies two rack units and ships with a single Intel Xeon E5-2643 v3 six-core processor running at 3.4 GHz. Sixty-four gigabytes of DDR4 ECC registered memory fill the 24 DIMM slots evenly, while the Smart Array P440 controller with 4 GB flash-backed write cache manages two 146 GB 15 K SAS drives in the front bays. Redundant hot-swap 500 W power supplies keep the platform running during a module failure.

Thermals noise and power under load

Dual redundant supplies share the load so each unit runs below its rated 500 W, allowing the fans to stay at lower speeds during typical database or virtualization workloads. The 2U chassis provides enough airflow path for the two processors and 24 memory modules without forcing high-RPM operation. Flash-backed cache on the P440 reduces write latency and eliminates the power draw of a battery-backed module.

Upgrading from single-socket towers or Gen8 racks

Teams moving from a single-socket tower or an earlier 2U generation gain a second processor socket, 24 DIMM slots and 16 SFF drive bays in the same rack footprint. The jump is worth it when workloads need more than 12 virtual cores, more than 64 GB of DDR4 or more than eight 2.5-inch SAS drives without adding another chassis.
