PowerEdge R940 4-Socket Server

The Dell PowerEdge R940 is a 3U rack-mount server system built for heavy compute workloads. Four Intel Xeon Gold 6142 processors deliver 64 total cores at 2.6 GHz with 3.7 GHz turbo. The chassis includes redundant hot-swap 1600 W power supplies, iDRAC9 Enterprise remote management and a front bezel with rails.

Enterprise database and virtualisation hosts

This configuration suits organisations running large in-memory databases, dense virtualisation or ERP platforms that benefit from four sockets and 512 GB of DDR4 registered ECC memory. Buyers who need more than 48 DIMM slots, internal GPU support or a smaller 1U/2U form factor should evaluate other platforms.

512 GB DDR4 with 48-slot expansion headroom

The system ships with sixteen 32 GB DDR4-2666 modules occupying 16 of 48 slots, leaving room to scale toward the 6 TB maximum. Memory type and slot count are fixed by the Intel C620 chipset and LGA 3647 sockets, so any upgrade must use registered DDR4 ECC modules.

Questions about this item

What is the typical noise and heat output when four Xeon Gold 6142 processors and dual 1600 Watt PSUs run continuously?

The server uses four 2.6 GHz 16-core Xeon Gold 6142 CPUs with a 3.7 GHz turbo frequency. Dual redundant 1600 Watt Platinum power supplies and hot-swap cooling are fitted for sustained operation.

Which cabling and rack hardware must already be in place for the 3U chassis and SAS storage to function?

The unit includes ready rails and a front bezel for a standard 3U rack. Eight 2.5-inch 1.2 TB 10K SAS drives connect to the PERC H730P controller, which supports SAS and SATA interfaces.

Can the existing X520/I350 network card and DDR4 memory work with older switches and expansion modules?

The Intel X520/I350 daughter card provides two 1 GbE and two 10 Gb SFP+ ports for mixed-speed networks. Installed memory is 512 GB DDR4 2666 MHz registered ECC across 16 modules, with 48 total slots supporting up to 6 TB.
