2U rack server for general-purpose workloads

The HPE ProLiant DL380 Gen10 P20245-B21 is a 2U rack server built for general-purpose workloads. It ships with one Intel Xeon 6242 processor running at 2.8 GHz with 16 cores and 22 MB L3 cache. A single 32 GB DDR4 RDIMM is installed, and the system supports optional Intel Optane persistent memory up to 1 TB per processor. One 800 W hot-plug power supply is included.

Sustained load on 16 cores with 150 W TDP

The Xeon 6242 operates at a 150 W thermal design power across its 16 cores, allowing the server to maintain 2.8 GHz under continuous multi-threaded demand. The 800 W Flex Slot supply provides headroom for the CPU, memory, and up to eight small-form-factor drives. HPE iLO Standard with Intelligent Provisioning enables remote monitoring of thermals and power draw during extended runs without requiring a local console.

Upgrades from single-socket towers or older 2U units

This configuration replaces single-socket tower servers or earlier 2U platforms that lack 25 Gb networking and persistent-memory support. The jump is worthwhile when workloads need 16 cores, 25 Gb SFP28 connectivity via the 640FLR-SFP28 adapter, and the option to add Optane persistent memory for low-latency data tiers. Buyers who need dual processors pre-installed, embedded networking, or drives included should evaluate other configurations.

Questions about this item

How much heat does the Xeon 6242 16-core 2.8 GHz processor add to the rack when the DL380 Gen10 runs continuously?

The installed Xeon 6242 has a 150 W thermal design power, so the 800 W Flex Slot supply must dissipate that load plus memory and controller draw under sustained operation.

What cabling or drives must I already have to use the P408i-a storage controller in this server?

The server ships with no drives; you need to provide SFF drives and the matching backplane cables for the eight supported bays.

Will the 10/25Gb 640FLR-SFP28 adapter work with my existing 1 Gb switches?

The 640FLR-SFP28 ports operate at 10 Gb or 25 Gb; they do not auto-negotiate down to 1 Gb, so you would need compatible 10 Gb or 25 Gb switching or a media converter.
