DELL PowerEdge R940 3U Rack Server 4x Xeon Gold 5118 2.3GHz 12-Core 256GB DDR4 8x 1.2TB SAS H730P

Quad-socket Xeon Gold server

The Dell PowerEdge R940 packs four Xeon Gold 5118 processors running at 2.3 GHz with 12 cores each, delivering 48 threads in a 3U rack chassis. It ships with 256 GB of DDR4 registered ECC memory across eight 32 GB modules and leaves 40 slots open for expansion up to 6 TB. This density targets virtualisation clusters, in-memory databases and analytics workloads that demand high core counts and large memory footprints.

PERC H730P controller and quad-port networking

The integrated PERC H730P with 2 GB cache supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through, managing the eight installed 1.2 TB 10K SAS drives. The Intel X520/I350 daughter card adds two 1 GbE and two 10 Gb SFP+ ports for flexible LAN and storage networking. iDRAC 9 Enterprise provides full out-of-band management with virtual console and lifecycle automation.

Tool-less rails and redundant power simplify

Sliding ready rails allow single-person rack mounting without tools, while the bezel snaps on for a clean front. Dual 1600 W platinum hot-swap supplies maintain uptime during maintenance. Installers must populate all four CPU sockets and balance memory across the 48 slots for optimal performance; incorrect DIMM placement is the most common cause of POST delays.
