Dense 1U dual-socket server

The Dell PowerEdge R640 is a 1U rackmount server built for dense scale-out data centre computing. It ships with two Intel Xeon Gold 5118 processors, each running at 2.3 GHz with 12 cores. The system includes 64 GB of DDR4 registered ECC memory across 24 slots. A PERC H730P controller manages SAS and SATA drives.

Suits virtualisation clusters

This configuration fits environments that need high core density and redundant power in a single rack unit. The dual 750 W platinum supplies and hot-swap design support continuous operation. Buyers who require more than two processors, GPU acceleration, or additional drive bays beyond the eight 2.5-inch slots should consider larger chassis options.

Eight 2.5-inch SAS/SATA drive bays with H730P RAID

Storage connectivity centres on the PERC H730P 2 GB controller supporting RAID 0, 1, 5, 6, 10, 50 and 60. Two 300 GB 10 K SAS drives are installed, leaving six bays for expansion. The controller’s battery-backed cache protects write data during power loss.

Questions about this item

How do I confirm the 2x Xeon Gold 5118 12-core processors are recognised after setup?

Check the BIOS or iDRAC9 Enterprise inventory; both should show two CPUs, 24 total cores and a base speed of 2.3 GHz.

What ships in the box and what must be sourced separately?

The unit includes the 1U chassis, 2 CPUs, 64 GB DDR4 (4x 16 GB), H730P controller, 2x 300 GB SAS drives, X520/I350 quad-port card, iDRAC9 Enterprise, 2x 750 W PSUs, rails and bezel. Additional drives or memory are not included.

Which memory configuration should I choose for this R640?

The server has 24 DDR4 slots and supports up to 3 TB; the installed 64 GB uses four 16 GB registered ECC modules at 2400 MHz. Add matching DDR4 RDIMMs in multiples of four for best performance.
