Four-socket Xeon Gold server

The Dell PowerEdge R940 is a 3U rack server with four Intel Xeon Gold 6142 processors running at 2.6 GHz with a 3.7 GHz turbo frequency. Each CPU provides 16 cores for a total of 64 cores across the system. It ships with 512 GB of DDR4 2666 MHz registered ECC memory installed across 16 DIMM slots. The chassis includes redundant 1600 W platinum power supplies, iDRAC9 Enterprise remote management, ready rails and a front bezel.

Database and virtualisation workloads

This server suits organisations running large databases, in-memory analytics or dense virtualisation clusters that benefit from four sockets and high core counts. The PERC H730P controller supports RAID 0, 1, 5, 6, 10, 50 and 60 with a 2 GB battery-backed cache. Buyers who need more than eight 2.5-inch drive bays, integrated GPU compute or a lower power envelope should evaluate alternative platforms.

Eight 2.5-inch SAS/SATA drive bays

The chassis provides eight hot-swap trays for 2.5-inch SAS or SATA drives with no drives installed. The H730P controller connects to the backplane at 12 Gb/s. Network connectivity comes from an Intel X520/I350 daughter card delivering two 1 GbE and two 10 GbE SFP+ ports. Memory capacity can scale to 6 TB across 48 slots when fully populated.

Questions about this item

How can I verify the four Xeon Gold 6142 processors are recognised after installation?

The iDRAC9 Enterprise remote management interface reports all four sockets and 64 total cores during POST and in the system inventory.

Which drives and cables must I supply myself?

The server includes eight 2.5" SAS/SATA trays and the PERC H730P controller; no drives or drive cables are included.

Is the installed 512 GB DDR4 2666 MHz memory expandable and how many slots remain free?

16 of the 48 DIMM slots are populated with 32 GB modules; 32 slots are available for further DDR4 registered ECC expansion up to 6 TB.
