Mission-critical 4-socket server

The Dell PowerEdge R940 is a 3U rack server built around four Intel Xeon Gold 5118 processors running at 2.30 GHz with a 3.2 GHz turbo frequency. Each CPU provides 12 cores, delivering 48 total cores for heavily threaded workloads. The system ships with 64 GB of DDR4 2400 MHz registered ECC memory across 48 available slots. It targets organisations running databases, virtualisation clusters or analytics that demand maximum socket density in a compact rack footprint.

Enterprise storage and networking

Eight 1.2 TB 10K SAS drives connect to a PERC H730P controller with 2 GB cache, supporting RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode. A quad-port network daughter card adds two 1 GbE and two 10 Gb SFP+ links for flexible fabric integration. Dual 1600 W platinum hot-swap power supplies and iDRAC9 Enterprise remote management keep the platform running and serviceable without physical access. Rails and a front bezel are included for immediate rack deployment.

Scalability within the 3U limit

Memory capacity can grow to 6 TB using the 48 DDR4 slots, but the four-socket maximum is already populated so CPU expansion stops here. The 2.5-inch drive bay count is fixed at eight, limiting internal SAS or SATA storage to the installed 1.2 TB drives unless external enclosures are added. Network bandwidth is capped at the provided 10 Gb SFP+ interfaces; no additional onboard ports exist. Buyers needing more internal drives, higher single-thread frequency or GPU acceleration must look beyond this chassis.

Questions about this item

What SAS speed does the PERC H730P controller cap at in practice?

The Dell PERC H730P 2GB controller runs at 12Gb/s SAS and SATA with RAID 0, 1, 5, 6, 10, 50, 60 and pass-through.

What physical space and rails does the 3U chassis need to mount?

The 3U rack server occupies 3U of height and ships with Ready Rails and a front bezel for standard rack mounting.

How is the iDRAC 9 Enterprise configured on first boot, and what step is often missed?

Connect the dedicated management port, then set a static IP, username and password in the iDRAC setup wizard before deploying workloads.
