DELL PowerEdge R940 3U rack server 4× Xeon Gold 5118 2.3GHz 12-core 128GB DDR4 2× 800GB SSD

Four-socket Xeon Gold server

The Dell PowerEdge R940 is a 3U rack server populated with four Intel Xeon Gold 5118 processors, each running at 2.3 GHz with 12 cores. It ships with 128 GB of DDR4 registered ECC memory across eight 16 GB modules and includes a PERC H730P controller with 2 GB cache. Two 800 GB SATA SSDs are installed in the 2.5-inch drive bays.

Check rack space, power and networking

Confirm the rack can accommodate a 3U chassis and that the facility provides redundant feeds for the dual 1600 W platinum power supplies. The system uses LGA 3647 sockets and the Intel C620 chipset, so any processor upgrades must match that platform. Verify that the quad-port X520/I350 daughter card meets the required mix of 1 GbE and 10 Gb SFP+ connections.

Fits dense compute clusters

The four-socket design delivers 48 total cores in a compact 3U form factor, leaving 40 DIMM slots free for expansion up to 6 TB of DDR4 memory. Six additional 2.5-inch bays remain open for SAS or SATA drives behind the H730P controller, which supports RAID 0, 1, 5, 6, 10, 50 and 60. iDRAC 9 Enterprise provides remote management without consuming a PCIe slot, and the included rails and bezel simplify rack integration.
