Dell PowerEdge R640 4LFF dual Xeon server

The Dell PowerEdge R640 4LFF is a 1U rack-mount server system built for dense compute workloads. It ships with two Intel Xeon Silver 4210 processors, each running at 2.2 GHz with ten cores. The chassis supports four 3.5-inch drive bays and includes a PERC H740P RAID controller. Remote management is handled by iDRAC9 with an Enterprise license.

Suited for virtualisation hosts needing large

This configuration fits organisations that need 512 GB of DDR4 ECC registered memory across two sockets. The 7.68 TB maximum memory ceiling allows future expansion without replacing the platform. Buyers who require GPU acceleration or more than four 3.5-inch drives should evaluate alternative chassis designs.

512 GB DDR4 ECC registered memory installed

The system arrives with 512 GB of DDR4 ECC registered memory populated across the two processors. This capacity determines how many virtual machines or containers can run simultaneously. No storage drives are included, so the buyer must supply compatible SATA drives for the PERC H740P controller.
