Dell PowerEdge R640 4LFF Server

The Dell PowerEdge R640 is a 1U rack-mount server system designed for dense compute workloads. It ships with a single Intel Xeon Gold 6226R processor running at 2.9 GHz with 16 cores and 22 MB cache. The unit includes 64 GB of DDR4 ECC registered memory and a PERC H740P RAID controller. It targets IT teams needing flexible storage configuration in a compact form factor.

Capacity and headroom

The chassis supports up to four 3.5-inch SATA drive bays, though no drives are installed by default. Memory can scale from the installed 64 GB to a maximum of 7.68 TB across available DIMM slots. A second processor socket is vacant, allowing a doubling of core count to 32 cores total. The PERC H740P controller provides hardware RAID acceleration for the installed drive count.

SATA interface limits

The SATA drive interface caps individual drive throughput at the standard 6 Gb/s link speed, which becomes the bottleneck for high-IOPS workloads on spinning media. The integrated 10 GbE 2-port 562T adapter offers 10 Gb/s network bandwidth per port for data movement. Dual 750 W power supplies deliver redundancy for the configured components. Remote management is handled by iDRAC9 with Enterprise licensing.

Questions about this item

Will the Xeon Gold 6226R with 16 cores at 2.9 GHz work with my existing DDR4 ECC registered modules?

Yes, the server uses DDR4 ECC registered memory and supports up to 7.68 TB total capacity across its slots.

How can I confirm the PERC H740P RAID controller and iDRAC9 Enterprise are functioning after installation?

During POST the controller initialisation appears on screen, and the iDRAC9 web interface becomes reachable at its management IP once the network cable is connected.

Does the chassis include drive caddies for 3.5-inch SATA drives and both 750 W power supplies?

The 4 LFF bay chassis ships with two 750 W power supplies installed; drive caddies for 3.5-inch SATA drives are supplied separately.
