DELL PowerEdge R640 1U Rack Server 2x Xeon Gold 6142 2.6GHz 16-Core 128GB DDR4 2x 400GB SSD H730P

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.
