DELL PowerEdge R940 3U rack server 4× Xeon Gold 5120 2.2 GHz 14-core 256 GB DDR4 8× 400 GB SSD

Four-socket 3U rack server

The Dell PowerEdge R940 is a 3U rack-mount server equipped with four Intel Xeon Gold 5120 processors, each running at 2.2 GHz with 14 cores. It ships with 256 GB of DDR4 registered ECC memory across eight 32 GB modules. Eight 400 GB SATA SSDs are installed behind the front 2.5-inch drive bays. Dual 1600 W redundant power supplies and iDRAC9 Enterprise remote management are included.

Suits dense virtualisation and in-memory workloads

This configuration targets organisations running heavily threaded applications, large virtual-machine fleets or in-memory databases that benefit from 56 total cores and 256 GB of fast memory. The four-socket design and PERC H730P controller with 2 GB cache support RAID levels 0, 1, 5, 6, 10, 50 and 60. Buyers needing more than 256 GB of RAM or additional drive bays beyond the eight 2.5-inch slots should evaluate larger platforms.

56 cores and 256 GB DDR4 decide fit

The combined 56 processing cores and 256 GB of DDR4 memory are the primary determinants of whether this server matches the workload. The installed H730P controller manages the eight 400 GB SATA SSDs over a 12 Gb/s SAS/SATA interface. Network connectivity provides two 1 GbE and two 10 Gb SFP+ ports via the X520/I350 daughter card.
