2U 4-Bay Rack Server

The Dell PowerEdge R640 is a 2U rack-mount server system built for data-centre workloads. It ships with two Intel Xeon Gold 6246R processors running at 3.4 GHz, providing 16 cores per socket and 35.75 MB cache each. Memory capacity is 512 GB of DDR4 ECC registered RAM, expandable to 7.68 TB. The chassis holds four 3.5-inch SATA drive bays and includes a PERC H740P RAID controller. Remote management is handled by iDRAC9 Enterprise.

Virtualisation Hosts, Not GPU Farms

This configuration suits organisations running virtualisation clusters, database instances or memory-heavy applications that benefit from high core counts and large RAM. The dual 750 W power supplies and 10 GbE dual-port adapter support redundant operation. Buyers who need GPU acceleration, more than four 3.5-inch bays or a different drive interface should evaluate other platforms.

PERC H740P RAID Controller

The installed PERC H740P controller manages the four SATA bays and provides hardware RAID with cache protection. It determines which drive types and RAID levels are supported, so verifying compatibility with your storage plan is the single step that confirms this server fits the deployment.
