DELL PowerEdge R640 4LFF 1x Xeon Gold 5218 128GB DDR4 No Drive Rack Server

Purpose-built compute density

The Dell PowerEdge R640 fits four 3.5-inch drive bays into a 1U rack chassis, providing dense local storage alongside a single Intel Xeon Gold 5218 processor running at 2.3 GHz with 16 cores and 22 MB cache. 128 GB of DDR4 ECC registered memory is installed, and the PERC H740P RAID controller manages the SATA backplane. Remote administration uses iDRAC9 with an Enterprise licence, while dual 750 W power supplies and a 10 GbE 562T two-port adapter handle power and networking.

Fit and gaps

This configuration suits teams that need a compact 1U server with integrated RAID and high-speed networking for virtualisation, database or file workloads where 128 GB of memory is sufficient. Buyers who require two processors from day one, more than four 3.5-inch bays, or installed drives should look at other chassis or populate the empty bays before deployment. The single-socket layout also limits maximum memory to half the 7.68 TB platform ceiling.

Deciding specification

The defining constraint is the four-bay 3.5-inch chassis paired with the PERC H740P controller, which fixes the internal storage topology to SATA hard drives or SSDs and caps raw capacity at the number of populated bays.
