DELL PowerEdge R640 4LFF Xeon Gold 6226R 128GB DDR4 No Drive Rack Server

Dell PowerEdge R640 4LFF Server

The Dell PowerEdge R640 is a 1U rackmount server system built for dense compute workloads. It ships with one Intel Xeon Gold 6226R processor running at 2.9 GHz with sixteen cores and twenty-two megabytes of cache. One hundred twenty-eight gigabytes of DDR4 ECC registered memory are installed, and the chassis supports up to four 3.5-inch SATA drive bays. A PERC H740P RAID controller and dual 750 W power supplies are included.

Suits virtualisation hosts needing core density

This configuration suits virtualisation hosts, database nodes or hyper-converged clusters that benefit from sixteen cores and large DDR4 capacity. The single-socket layout leaves a second processor socket open for future expansion up to the two-socket maximum. Buyers who need more than four 3.5-inch drive bays, discrete GPU acceleration or a different drive interface should evaluate alternative chassis designs.

Four 3.5-inch SATA bays with PERC H740P RAID

The defining specification is the four-bay 3.5-inch SATA backplane paired with the PERC H740P hardware RAID controller. This combination determines how many spinning drives or SATA SSDs you can install internally and which RAID levels are supported. No drives are installed, so you must add compatible SATA media before deployment.
