Rack Server for Dense Storage

The Dell PowerEdge R640 is a 1U rack server fitted with two Intel Xeon Gold 5120 processors running at 2.2 GHz and 64 GB of DDR4 memory. It provides four 3.5-inch drive bays and a PERC H740P RAID controller for local storage arrays. Integrated graphics and a 10 GbE two-port adapter handle basic display and network needs.

Fits Standard Racks and High-Capacity Drives

The chassis measures 36 by 24 by 10 inches and weighs 40 units, sliding into a standard 19-inch rack with optional rails. Four large-form-factor bays accept 3.5-inch SATA drives, freeing internal space that smaller bays would occupy. Dual 750 W power supplies deliver redundancy without extra external hardware. iDRAC9 Enterprise enables remote firmware updates and monitoring over the network.

Suits Storage-Focused Workloads, Not GPU Compute

This configuration serves buyers who need dense 3.5-inch capacity and dual-socket processing for databases, virtualization or file serving. It does not accommodate dedicated GPU cards, so workloads requiring hardware acceleration should look elsewhere. Organizations needing pre-installed drives or a different drive-count layout must specify those changes before purchase.
