Dense 1U dual-socket server with 800 GB SATA SSDs

The Dell PowerEdge R640 is a 1U rack server fitted with two Intel Xeon Gold 6142 processors running at 2.6 GHz, each providing 16 cores. It ships with 256 GB of DDR4 registered ECC memory and eight 800 GB SATA solid-state drives managed by a PERC H730P controller.

Suits scale-out clusters needing strong per-core

Buyers who require GPU acceleration should evaluate other platforms because this 1U chassis provides no PCIe GPU space. Organisations needing more than 256 GB of memory or additional drive bays must look at larger form-factor servers.

16 cores per CPU at 2.6 GHz base clock

The two Xeon Gold 6142 processors deliver 32 total cores with a 3.7 GHz turbo frequency, setting the performance ceiling for compute-intensive workloads on this platform.

Questions about this item

What comes with the server and what must I add myself?

The unit ships with two Xeon Gold 6142 processors, 256 GB DDR4 in eight 32 GB modules, eight 800 GB SATA SSDs, a PERC H730P controller, an X520/I350 quad-port network card, iDRAC9 Enterprise, two 750 W redundant power supplies, rails and a front bezel. No extra components are required for basic operation.

Should I choose a different CPU or memory configuration for this R640?

This listing is fixed at two 16-core Xeon Gold 6142 CPUs at 2.6 GHz with 3.7 GHz turbo and 256 GB DDR4-2666. The board supports up to 3 TB across 24 slots, so you can add more DDR4 later, but the processor count is already at the maximum of two.

What does the 2.6 GHz figure mean once the server is running workloads?

Each of the 32 total cores runs at a 2.6 GHz base frequency and can boost to 3.7 GHz under load, giving consistent performance for virtualisation, databases and dense compute tasks within the 1U chassis.
