Dell PowerEdge R640 8-bay rack server

The Dell PowerEdge R640 is a 1U rackmount server system equipped with two Intel Xeon Silver 4114 processors. Each CPU runs at 2.20GHz with 10 cores, delivering 20 cores in total. It ships with 256GB of DDR4 memory and eight 1.2TB 10k SAS drives managed by an H740P controller.

Suited for virtualisation.

This configuration targets businesses running file storage, virtual machines, databases or backup workloads that benefit from the installed 256GB DDR4 and the eight SAS drive bays. Buyers who need more than 3TB of total memory or who require a different drive interface should look at other platforms.

Maximum memory capacity of 3TB

The system supports up to 3TB of DDR4 across its memory slots, so the 256GB fitted today can be expanded significantly. This single limit decides whether the server can grow with your workload or whether a larger platform is required.

Questions about this item

Should I pick the 1.2 TB 10k SAS drives or the 960 GB SSDs listed for this R640?

The product title specifies 8x 1.2 TB 10k SAS drives while the description mentions dual 960 GB SSDs; the installed configuration ships with the eight SAS drives and the H740P controller.

What does the 20-core total from the two Xeon Silver 4114 CPUs deliver in this server?

Two Silver 4114 processors at 2.20 GHz provide 20 cores and 40 threads, giving strong multi-threaded throughput for virtualization, databases and application hosting workloads.

How do the X540 and I350 network adapters limit real-world throughput?

The X540 dual-port 10GbE and I350 quad-port 1GbE interfaces cap traffic at 10 Gb/s and 1 Gb/s per port respectively, with actual speeds depending on cabling and switch capability.
