DELL PowerEdge R640 1U rack server 2x Xeon Silver 4116 2.1GHz 12-core 768GB DDR4

Dense 1U dual-socket platform

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data centre computing. It carries two Intel Xeon Silver 4116 processors, each with twelve cores running at 2.1 GHz and a 3.0 GHz turbo frequency. The system includes 768 GB of DDR4 2400 MHz registered ECC memory across twenty-four slots. Dual 750 W platinum power supplies and iDRAC9 Enterprise remote management come as standard.

Suited for virtualisation clusters

Organisations running large virtualisation clusters, in-memory databases or high-thread-count applications will benefit from the twenty-four memory slots and dual-socket design. The PERC H730P controller supports RAID 0, 1, 5, 6, 10, 50 and 60 with a 2 GB cache. Buyers who need more than two processor sockets, GPU acceleration or storage interfaces beyond SAS and SATA should evaluate alternative platforms.

24 DIMM slots define maximum memory capacity

The server provides twenty-four DDR4 DIMM slots with a factory ceiling of 3 TB, so the 768 GB installed today can grow substantially. All slots are populated with 32 GB modules in this configuration, meaning any expansion requires replacing existing sticks. The LGA 3647 socket and Intel C620 chipset limit upgrades to the current processor generation.
