PowerEdge R940 four-socket rack server

The Dell PowerEdge R940 is a 3U rack-mount server equipped 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 installed across 48 slots and includes a PERC H730P RAID controller with 2 GB cache. Dual 1600 W platinum power supplies and iDRAC9 Enterprise remote management come standard.

Suits dense virtualisation and in-memory workloads

This configuration targets organisations that run large virtual-machine clusters, in-memory databases or high-thread-count applications and need four sockets in a 3U chassis. The eight 2.5-inch SAS/SATA drive bays and quad-port 1GbE and 10Gb SFP+ networking support substantial I/O. Buyers who require more than eight internal drive bays, GPU compute modules or a form factor smaller than 3U should evaluate other platforms.

PERC H730P RAID controller with 2 GB cache

The storage subsystem centres on a Dell PERC H730P controller offering 12 Gb/s SAS/SATA connectivity and a 2 GB battery-backed cache. It supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode, giving flexibility for performance or redundancy. The server provides eight hot-swap 2.5-inch trays but no drives are included, so the buyer must populate bays with compatible SAS or SATA media.

Questions about this item

How do I confirm the four Xeon Gold 5118 processors are all recognised after powering on the R940?

The iDRAC9 Enterprise interface shows all four CPUs, 48 cores total, and 128 GB of DDR4 memory in its system inventory once the server completes POST.

The listing says eight 2.5" trays but no drives — what else must I purchase to populate the bays?

You need to buy 2.5" SAS or SATA drives separately; the PERC H730P controller supports RAID 0, 1, 5, 6, 10, 50 and 60 for any combination you install.

Which memory configuration should I choose if I want to expand beyond the installed 128 GB?

The R940 has 48 DDR4 slots and supports up to 6 TB; add registered ECC DDR4 2400 MHz modules in matched sets to keep all four processor channels balanced.
