DELL PowerEdge R640 4LFF 1x Xeon Gold 6138 128GB DDR4 No Drive Server

Dell PowerEdge R640 4LFF server

The Dell PowerEdge R640 is a 1U rack-mount server system built for compute-intensive workloads. It ships with one Intel Xeon Gold 6138 processor running at 2.0 GHz with 20 cores and 27.5 MB cache. Installed memory is 128 GB of DDR4 ECC registered RAM. The chassis provides four 3.5-inch drive bays and includes a PERC H740P RAID controller.

Suits single-socket deployments needing high core

This configuration fits virtualisation hosts, database nodes or HPC clusters that run well on one 20-core CPU and 128 GB of memory. The second processor socket is empty for future expansion. Buyers who require dual-socket performance from day one or who need more than four 3.5-inch drive bays should evaluate larger chassis options.

Four 3.5-inch drive bays with PERC H740P

The single specification that decides fit is the 4LFF bay count paired with the PERC H740P controller. It defines how many mechanical drives you can install and which RAID levels are supported. If your storage plan exceeds four 3.5-inch disks or demands a different controller feature set, this chassis will not meet the requirement.
