Quad-socket Xeon server for dense compute

The Dell PowerEdge R940 fits four Intel Xeon Gold 6142 processors into a 3U rack chassis, delivering 64 cores at 2.6 GHz with 3.7 GHz turbo. It targets organisations that need maximum thread count in minimal rack space for virtualisation, database or high-performance workloads.

Four physical CPUs installed

This unit ships with all four LGA 3647 sockets populated by 16-core Xeon Gold 6142 chips, reaching the platform's processor limit. Buyers who need room for future CPU upgrades should note that no additional sockets remain.

Redundant 1600 W power supplies sustain full load

Dual hot-swap platinum-efficiency PSUs share the draw so the system maintains all 64 cores at turbo frequency without throttling. The 2.5-inch drive bays and PERC H730P controller add storage throughput while the quad-port 10 GbE and 1 GbE daughter card keeps network pipes full during extended runs.

Questions about this item

How does having four 16-core Xeon Gold 6142 processors affect real-world throughput?

With four processors each running 16 cores at 2.6 GHz and turbo up to 3.7 GHz, the server delivers 64 physical cores for heavy parallel workloads such as virtualization or database processing.

What practical throughput does the PERC H730P 12Gb/s SAS controller provide for the installed drives?

The H730P supports 12Gb/s SAS and SATA with RAID 0, 1, 5, 6, 10, 50, 60 and pass-through, giving the two 300GB 10K SAS drives full controller bandwidth for redundant or striped arrays.

What rack depth and mounting hardware are required to install this 3U chassis?

The unit is a 3U rack server that ships with ready rails and a front bezel; it fits standard four-post racks using the included sliding rail kit for tool-less mounting.
