DELL PowerEdge R640 8SFF Xeon Gold 6248R 128GB DDR4 No Drive

1U Rack Server for Scale-Out Compute

The Dell PowerEdge R640 is a 1U rack-mount server designed for dense, scale-out workloads. It arrives with a single Intel Xeon Gold 6248R processor running at 3 GHz and 24 cores. 128 GB of DDR4 ECC registered memory is installed. The chassis supports up to eight 2.5-inch drive bays and includes a PERC H740P RAID controller.

Upgrade Path from Single-Socket Density Limits

This configuration adds a second processor socket for up to two CPUs, raising the core ceiling when single-socket throughput is exhausted. Memory capacity expands to 7.68 TB across the full DIMM complement. The jump is worth it when virtualization density or database concurrency outgrows the initial 24-core, 128 GB baseline.

Headroom for Virtualisation and Storage Growth

Eight 2.5-inch bays fed by the H740P handle mixed SSD and HDD arrays for boot, cache or capacity tiers. Dual 750 W supplies and a 10 GbE 562T adapter provide power and network headroom for clustered deployments. The platform runs out when workloads demand GPU acceleration or more than two sockets.
