Dell PowerEdge R940 3U Server

The Dell PowerEdge R940 is a 3U rack server built for heavy compute workloads. It ships with four Intel Xeon Gold 5118 processors running at 2.3 GHz with 12 cores each. The system includes 64 GB of DDR4 registered ECC memory and a PERC H730P storage controller. Dual 1600 W redundant power supplies and iDRAC 9 Enterprise remote management come standard.

Suits four-socket density in 3U.

This server suits organisations that need four-socket performance within a 3U footprint. It supports up to 48 DIMM slots for large memory capacity. Buyers who only need a single or dual-socket platform should look at smaller rack models. Environments without 10 Gb SFP+ networking infrastructure will not use the installed daughter card.

Four Xeon Gold 5118 CPUs installed

The decisive specification is the four factory-installed Xeon Gold 5118 processors at 2.3 GHz with 12 cores each. The LGA 3647 sockets are fully populated at the maximum of four CPUs. Memory runs as DDR4 across 48 slots with a 6 TB ceiling. Storage uses the H730P controller with two 400 GB SATA SSDs installed in the 2.5-inch drive bays.

Questions about this item

What rack height and rail kit does the R940 need for mounting?

The server is a 3U rack unit and ships with Ready Rails for installation in a standard rack.

How are the four Xeon Gold 5118 processors and DDR4 memory installed, and what step is often missed?

All four CPU sockets are populated at 2.3 GHz with 12 cores each; the 64 GB DDR4 2400 MHz memory uses 4 of 48 slots, so remaining slots must be filled in matched sets per processor.

Which drive bays and power supplies are hot-swappable for later replacement?

The 8-bay 2.5-inch front chassis supports hot-swap SATA SSDs, and the two 1600 W redundant power supplies are also hot-swappable.
