DELL PowerEdge R640 4LFF Xeon Silver 4210R 256GB DDR4

PowerEdge R640 4LFF server

The Dell PowerEdge R640 is a 1U rack-mount server system built around a single Intel Xeon Silver 4210R processor running at 2.4GHz with ten cores. It arrives with 256GB of DDR4 ECC registered memory installed across sixteen 16GB modules and includes a PERC H740P RAID controller. The chassis supports up to four 3.5-inch SATA drive bays, though no drives are fitted in this configuration. Dual 750W power supplies and an iDRAC9 Enterprise licence provide redundant power and full remote management out of the box.

Suited for memory-heavy workloads

This server suits organisations that need a dense, single-socket platform with a large DDR4 footprint for virtualisation, database caching or compute tasks that benefit from 256GB of registered memory. The four 3.5-inch bays and PERC H740P controller give flexibility for high-capacity SATA storage arrays. Buyers who require dual-processor throughput immediately, GPU-accelerated workloads, or a chassis populated with drives should look at other configurations, as this unit ships with one CPU, integrated graphics only and empty drive bays.

256GB DDR4 decides fit

The installed 256GB DDR4 ECC registered memory is the specification that determines whether this system matches the workload. The board accepts up to 7.68TB total, so the current 16-module population leaves room for expansion if the application grows. Verify that the operating system and applications are licensed for this memory capacity and that the single Xeon Silver 4210R provides sufficient thread count before deployment.
