DELL PowerEdge R640 4LFF 2x Xeon Gold 5120 128GB DDR4 No Drive rack server

Four 3.5" drive bay chassis

The Dell PowerEdge R640 is a 1U rack server configured with four large-form-factor bays for 3.5-inch SATA drives. Two Intel Xeon Gold 5120 processors at 2.2 GHz provide 28 cores in total, backed by 128 GB of DDR4 ECC registered memory. A PERC H740P RAID controller and a 10 GbE two-port 562T adapter handle storage and network traffic. Remote management is covered by iDRAC9 Enterprise, and dual 750 W power supplies deliver redundancy.

Suits virtualisation hosts needing dense 3.5"

This configuration fits workloads that demand high core counts and large-capacity hard drives in a single rack unit. Buyers who require more than four drive bays, GPU acceleration, or a different drive interface should evaluate alternative platforms. The fixed two-processor maximum also limits future CPU expansion beyond the installed pair.

PERC H740P RAID controller with 10 GbE networking

The integrated PERC H740P controller manages RAID across the four 3.5-inch SATA bays, while the onboard 562T adapter supplies two 10 GbE ports for high-throughput connectivity. This combination determines whether the server matches your storage-performance and network-bandwidth requirements.
