DELL PowerEdge R640 4LFF 2x Xeon Gold 6226 768GB DDR4

Dual-socket Xeon Gold 6226 server

The Dell PowerEdge R640 delivers two Intel Xeon Gold 6226 processors at 2.7 GHz with twelve cores each and 19.25 MB cache. It ships with 768 GB of DDR4 ECC registered memory and a PERC H740P RAID controller in a 4 LFF chassis that accepts four 3.5-inch SATA drives. The integrated iDRAC9 Enterprise remote management and a dual-port 10 GbE 562T adapter support data-centre deployment.

Before ordering check chassis depth and power

The unit measures 36 by 24 by 10 inches and weighs 40 pounds, so verify rack depth and weight capacity before installation. Two 750 W power supplies are included; confirm your PDU connectors and available U-space for the 1U form factor. No drives are installed, so plan the number and capacity of 3.5-inch SATA drives you will add. Ensure the operating system and hypervisor support the installed PERC H740P controller and iDRAC9 Enterprise licence.

Sustained load behaviour

Dual 750 W supplies and updated firmware maintain stable operation during extended compute tasks. The 768 GB DDR4 ECC memory supports long-running virtualisation and database workloads without correctable-error interruption. PERC H740P write-back cache with flash-backed protection preserves data integrity during prolonged I/O streams. iDRAC9 Enterprise provides continuous thermal and power telemetry for proactive capacity management.
