Dell PowerEdge R640 4LFF Server

The Dell PowerEdge R640 is a 1U rack server built for virtualisation and database workloads. It ships with one Intel Xeon Silver 4208 processor at 2.1 GHz and 128 GB of DDR4 ECC registered memory. A second processor socket is available for future expansion.

Build and connectivity

The 4LFF chassis holds up to four 3.5-inch SATA drive bays and includes a PERC H740P RAID controller. Dual 750 W power supplies provide redundancy. Remote management is handled by iDRAC9 Enterprise, and a 10 GbE two-port 562T adapter is installed for high-speed networking.

Pre-purchase checks

No hard drives are installed; you must supply compatible 3.5-inch SATA drives. Verify that your rack can accommodate the 36 x 24 x 10 inch form factor and 40 lb weight. Ensure DDR4 ECC registered modules are used for any memory upgrades.
