Four-socket 3U rack server

The Dell PowerEdge R940 is a 3U rack-mount server system built around four Intel Xeon Gold 5118 processors, each running at 2.3 GHz with 12 cores. It ships with 512 GB of DDR4 registered ECC memory across 16 DIMM slots and a Dell PERC H730P storage controller with 2 GB cache. Eight 1.2 TB 10K SAS drives and a quad-port network daughter card providing two 1 GbE and two 10 Gb SFP+ connections are included.

Suited for dense virtualisation.

This configuration suits organisations that need maximum CPU core count and memory capacity in a compact 3U form factor for virtualisation, database or analytics workloads. The four-socket design scales to 48 cores and 6 TB of memory, and iDRAC 9 Enterprise enables full remote management. Buyers who require GPU acceleration, additional drive bays beyond the eight 2.5-inch slots, or a tower form factor should consider other platforms.

Four physical CPUs installed, no sockets free

The defining specification is that all four LGA 3647 processor sockets are already populated with Xeon Gold 5118 CPUs, so no further processor upgrades are possible. Memory can still be expanded to the 6 TB maximum using the remaining 32 DIMM slots, and the PERC H730P controller supports RAID levels 0, 1, 5, 6, 10, 50 and 60. Redundant 1600 W platinum power supplies and sliding rails are included.

Questions about this item

What rack mounting hardware is included so the server can be installed immediately?

Ready Rails and a front bezel are included with the R940 for direct rack installation.

Can the existing eight 1.2 TB SAS drives stay in place if I add more storage later?

The PERC H730P controller supports RAID 0, 1, 5, 6, 10, 50, 60 and pass-through, so the current drives remain usable when expanding.

How can I verify the four Xeon Gold 5118 processors are all recognised after power-on?

iDRAC 9 Enterprise remote management will display all four CPUs and 512 GB of DDR4 memory in its system inventory.
