DELL PowerEdge R640 4LFF 2x Xeon Silver 4210 64GB DDR4 No Drive rack server

What it is

The Dell PowerEdge R640 is a 1U rack server built around two Intel Xeon Silver 4210 processors running at 2.2 GHz with ten cores each and 64 GB of DDR4 ECC registered memory. It ships with a PERC H740P RAID controller and a 10 Gb dual-port 562T network adapter but no drives installed. Remote management is handled by iDRAC9 Enterprise and dual 750 W power supplies provide redundancy. The chassis supports up to four 3.5-inch SATA drive bays and maximum memory capacity reaches 7.68 TB.

Who it suits

This configuration fits organisations that need a dense two-socket platform for virtualisation, database or general compute workloads where 10 Gb networking and hardware RAID are required out of the box. Buyers who need more than four 3.5-inch drive bays or who require a different drive interface should look elsewhere. The fixed 1U height also limits expansion cards to low-profile slots.

Deciding specification

The four-bay 3.5-inch SATA chassis with a PERC H740P controller is the single spec that determines fit; it defines both the maximum number of spinning drives you can install and the RAID levels available without adding a second controller.
