DELL PowerEdge R940 3U rack server 4x Xeon Gold 6142 2.6GHz 16-core 512GB DDR4 8x 2.4TB SAS H730P

Four-socket 3U rack server

The Dell PowerEdge R940 is a 3U rackmount server populated with four Intel Xeon Gold 6142 processors, each running at 2.6 GHz with 16 cores. It ships with 512 GB of DDR4 2666 MHz registered ECC memory across 16 DIMM slots and includes a PERC H730P 2 GB storage controller with battery-backed cache. Eight 2.4 TB 10K SAS drives fill the front bays, and dual 1600 W platinum power supplies provide redundancy.

Dense compute for memory-heavy workloads

This configuration suits organisations running large in-memory databases, virtualisation clusters or analytics platforms that benefit from 64 total cores and half a terabyte of RAM. Buyers who only need one or two processors, or who require flash storage instead of 10K SAS capacity, should look at a different platform. The 48 DIMM slots and 6 TB maximum memory allow substantial future expansion without changing chassis.

64-core Xeon Gold 6142 foundation

The decisive specification is the quartet of 16-core Xeon Gold 6142 CPUs delivering 64 cores at 2.6 GHz base and 3.7 GHz turbo. This processor count and core density determine whether the server matches the threading demands of the target application. All other components scale around this compute core.
