Dual-Socket 1U Rack Server

The Dell PowerEdge R640 is a 1U rackmount server built for dense scale-out data centre workloads. It ships with two Intel Xeon Gold 6148 processors running at 2.40 GHz with 20 cores each, 768 GB of DDR4 2666 MHz registered ECC memory across 24 slots, and a PERC H730P 2 GB RAID controller. Eight 600 GB 10K SAS drives and dual 750 W platinum power supplies complete the configuration.

Suited for virtualisation hosts

This system fits buyers who need dual-socket compute density in a single rack unit with redundant power and integrated remote management via iDRAC 9 Enterprise. It does not suit buyers who require more than 3 TB total memory capacity, more than two processors, or storage interfaces other than SAS and SATA.

3 TB maximum memory ceiling

The Intel C620 chipset supports up to 3 TB of DDR4 across 24 DIMM slots, so the 768 GB installed leaves room for expansion within that limit. Memory type is fixed to DDR4 registered ECC; other generations or unbuffered modules will not work.

Questions about this item

Does the server ship with all eight 600 GB SAS drives and the H730P RAID controller already installed?

Yes, eight Dell Enterprise 600 GB 10K SAS 12 Gb/s 2.5" drives and the PERC H730P 2 GB 12 Gb/s SAS/SATA controller with battery are included.

Should I pick the 768 GB DDR4 configuration or add more memory later?

The system arrives with 768 GB (24 x 32 GB) DDR4 2666 MHz registered ECC filling all 24 slots; maximum capacity is 3 TB if you replace modules with higher-density DIMMs.

What does the dual Xeon Gold 6148 2.4 GHz 20-core setup deliver in this 1U chassis?

Two Intel Xeon Gold 6148 processors provide 40 cores total at 2.4 GHz base and 3.7 GHz turbo, supported by the C620 chipset and redundant 750 W platinum power supplies.
