Dense 1U dual-socket server

The Dell PowerEdge R640 packs two Intel Xeon Gold 6142 processors and 128GB of DDR4 ECC memory into a single rack unit. It targets organisations that need high core density for virtualisation, databases or high-performance computing workloads in space-constrained data centres.

Tool-less rails and hot-swap components

Ready Rails allow the chassis to slide into a standard rack without tools. All eight 2.5-inch drive bays, both 750W power supplies and the PERC H730P controller battery are hot-swappable. The only common snag is forgetting to seat the RAID battery fully, which prevents write-back caching from activating.

24 DDR4 slots capped at 3TB

The system board provides 24 DIMM slots supporting registered DDR4 2666MHz modules up to a 3TB maximum. Buyers planning larger memory footprints must verify module rank and voltage compatibility before purchasing additional sticks.

Questions about this item

How can I verify both Xeon Gold 6142 processors are detected after installation?

Enter the BIOS or iDRAC9 Enterprise interface; both should show 2 sockets populated with 16 cores each at 2.6 GHz base clock and 3.7 GHz turbo.

Which components ship with the server and which must be sourced separately?

The unit includes 2 CPUs, 128 GB DDR4 in 8 DIMMs, 2 x 400 GB SATA SSDs, H730P controller, X520/I350 quad-port NIC, 2 x 750 W PSUs, rails and bezel; additional drives or memory are not included.

Which drive capacity matches the factory configuration shown?

The server comes with 2 x 400 GB SATA SSDs; other capacities are not part of this build.
