DELL PowerEdge R640 1U Rack Server 2x Xeon Gold 6148 2.4GHz 20-Core 256GB DDR4 H730P

Dense 1U dual-socket server

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data centre computing. It carries two Intel Xeon Gold 6148 processors, each with 20 cores running at 2.4 GHz and a 3.7 GHz turbo frequency. The system includes 256 GB of DDR4 2666 MHz registered ECC memory across eight 32 GB modules. Redundant 750 W platinum power supplies and a Dell PERC H730P 2 GB RAID controller with battery-backed cache complete the core platform.

Suited for virtualisation clusters

This configuration suits organisations that need high core counts and large memory capacity in a single rack unit for virtualisation clusters, in-memory databases or high-performance computing workloads. The eight 2.5-inch drive trays support SAS and SATA media, and the quad-port network daughter card provides two 1 GbE and two 10 Gb SFP+ connections. Buyers who require more than 24 memory slots, more than two processor sockets or internal GPU expansion should look elsewhere, as the chassis does not accommodate those needs.

24 DDR4 slots define maximum memory

The motherboard provides 24 DDR4 DIMM slots with a maximum supported capacity of 3 TB, so the installed 256 GB can be expanded significantly using registered ECC modules. The LGA 3647 socket and Intel C620 chipset limit processor upgrades to the Xeon Scalable family supported by this generation. Verify that your memory modules and any additional CPUs match the DDR4 2666 MHz registered ECC specification and the LGA 3647 socket before purchasing.
