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.

Perguntas sobre este artigo

What rack depth and clearance does the 36-inch deep R640 chassis require?

The server measures 36 inches deep, 24 inches wide and 10 inches high, weighing 40 pounds, so allow at least 36 inches of usable rack depth plus cable bend radius behind the rear panel.

Which step is often missed when seating the PERC H740P controller and its 2.5-inch drive cables?

The PERC H740P RAID controller must be fully latched into its dedicated slot and the drive data cables pressed until they click; a loose cable leaves the backplane invisible at POST.

When will the 128GB of DDR4 ECC registered memory need expansion beyond the current DIMM population?

The system supports up to 7.68TB total DDR4 capacity across 24 slots; adding workloads that exceed the installed 128GB will require populating empty slots with matching registered modules.
