Quad-Socket Compute Density

The Dell PowerEdge R940 packs four Intel Xeon Gold 5120 processors, each with 14 cores running at 2.2 GHz and a 3.2 GHz turbo frequency, into a 3U rack chassis. This configuration targets organisations running memory-intensive workloads such as in-memory databases, virtualisation clusters or real-time analytics where core count and memory capacity matter more than single-thread speed.

Enterprise Build With Hot-Swap Flexibility

Redundant 1600 W platinum power supplies and hot-swap 2.5-inch drive bays let you replace components without downtime. The PERC H730P controller with 2 GB cache supports RAID 0, 1, 5, 6, 10, 50 and 60 across eight 400 GB SATA SSDs, while the X520/I350 daughter card delivers two 1 GbE and two 10 Gb SFP+ ports for flexible network segmentation.

Verify Rack Space, Memory Growth And Network Cabling

Confirm your rack can accommodate a 3U unit with the included rails and that power distribution can handle dual 1600 W feeds. The system ships with 768 GB across 24 DIMM slots, leaving 24 slots open for expansion up to 6 TB of DDR4 registered ECC memory. Ensure you have SFP+ transceivers and cabling for the 10 Gb ports, as they are not supplied.

Questions about this item

What storage interface does the PERC H730P controller use, and what throughput does it cap at?

The PERC H730P is a 12 Gb/s SAS and SATA controller, so installed SATA SSDs are limited to the 6 Gb/s SATA link speed.

What physical space and mounting hardware does this 3U server require?

The R940 occupies 3U of rack height and ships with ready rails and a front bezel for standard rack mounting.

How are the eight 400 GB SSDs installed, and what step is often missed?

The 2.5-inch SSDs slide into the front hot-swap bays; the RAID array must be configured in the PERC H730P BIOS before the OS sees a usable volume.
