Dell PowerEdge R640 8SFF Server

The Dell PowerEdge R640 8SFF is a 1U rack server built for virtualization and database workloads. It ships with two Intel Xeon Silver 4210 processors running at 2.2GHz and 256GB of DDR4 ECC registered memory. The chassis supports up to eight 2.5-inch SATA drive bays and includes a PERC H740P RAID controller. This configuration arrives without installed drives.

Verify Rack Space and Power Infrastructure

Confirm your rack provides 36 inches of depth and 10 inches of height for this 1U unit. The system weighs 40 pounds and requires two 750W power supplies connected to compatible PDU outlets. Ensure network cabling supports the installed dual-port 10GbE 562T adapter for iDRAC9 Enterprise remote management. BIOS and firmware are updated to the latest stable version before shipment.

Dual 750W Supplies Handle Peak Loads

Two 750W power supplies deliver redundant power for the dual 10-core processors and full memory population. Fan speeds adjust dynamically to maintain thermal limits across the 24-inch width chassis during sustained compute tasks. Acoustic output scales with workload intensity in typical data-center environments. The iDRAC9 Enterprise license enables continuous thermal monitoring and alerting.
