HP ProLiant DL380 Gen9 2U rack server E5-2643 v3 6C 3.4GHz 128GB DDR4 2x 146GB SAS P440 4GB FBWC

2U rack server for dense compute

The HP ProLiant DL380 Gen9 fits in a 2U rack space and ships with a single Intel Xeon E5-2643 v3 six-core processor running at 3.4GHz. It provides 128GB of DDR4 ECC registered memory across 24 DIMM slots, reaching the installed maximum. The Smart Array P440 controller with 4GB flash-backed write cache manages two 146GB 15K SAS drives in 16 small-form-factor bays. Redundant 500W hot-swap power supplies are included.

Thermals noise and power in normal use

Dual redundant 500W power supplies share the load and allow one unit to fail without downtime. The 2U chassis uses multiple hot-swap fans that adjust speed based on inlet temperature and component load. Under typical mixed workloads the system draws a fraction of the available 500W per supply while fan noise remains at data-centre background levels. Hot-swap components let you replace a supply or drive without powering down.

Upgrade path and when the jump matters

This configuration maxes the installed memory at 128GB and uses a single processor; adding a second Xeon E5 v3 doubles cores and unlocks the remaining 12 DIMM slots for up to 3TB total capacity. The 16-bay SFF cage can grow to 24 bays with an optional rear cage, and the P440 controller supports RAID 0/1/5/6/10/50/60 across all drives. Buyers who need more than two 146GB drives or who require a second CPU from day one should plan those additions before deployment.
