DELL PowerEdge R640 1U rack server 2x Xeon Platinum 8160 2.1GHz 24-core 768GB DDR4 8x 1.2TB SAS H730P

Dual-socket 1U rack server

The Dell PowerEdge R640 is a 1U rack-mounted server system built for dense scale-out data center computing. It ships with two Intel Xeon Platinum 8160 processors, each running at 2.1 GHz with 24 cores and a 3.7 GHz turbo frequency. The system includes 768 GB of DDR4 2666 MHz registered ECC memory across 24 DIMM slots, with a maximum capacity of 3 TB. A PERC H730P 2 GB controller manages eight 1.2 TB 10K SAS drives in 2.5-inch bays.

Virtualisation hosts and database clusters

This configuration suits workloads that demand high core counts and large memory footprints, such as virtualisation hosts, in-memory databases or high-performance computing nodes. The dual-socket design maximises thread density within a single rack unit, while redundant 750 W power supplies and hot-swap drive bays support continuous operation. Organisations needing more than two processor sockets or storage interfaces beyond SAS and SATA should evaluate alternative platforms.

768 GB DDR4 registered ECC memory

The installed 768 GB of DDR4 2666 MHz registered ECC memory across 24 slots is the specification that determines fit for memory-intensive applications. The platform supports up to 3 TB total capacity, allowing future expansion within the same chassis. Buyers must verify that their workloads and operating systems can address this memory configuration and that any additional modules match the registered ECC DDR4 standard.
