DELL PowerEdge R640 4LFF Xeon Gold 5122 3.6GHz 256GB DDR4 No Drive

Purpose-built rack server

The Dell PowerEdge R640 chassis holds up to four 3.5-inch SATA drive bays and ships with a PERC H740P RAID controller, dual 750 W supplies and an iDRAC9 Enterprise licence. A single Xeon Gold 5122 running at 3.6 GHz with four cores and 16.5 MB cache is paired with 256 GB of DDR4 ECC registered memory across sixteen 16 GB modules.

Scales from single-socket to dual-socket

One processor socket is populated and a second is free, so the system can move from four to eight cores without a chassis change. The memory ceiling reaches 7.68 TB, allowing gradual expansion as workloads grow. The integrated 10 GbE 562T two-port adapter handles high-throughput networking from day one.

Fits dense virtualisation and database clusters

Organisations that need a 1U rack footprint with flexible 3.5-inch storage and remote management will match this spec. Buyers who want more storage bays, GPU acceleration or a different drive interface should look at other chassis.
