Dense 1U compute node

The Dell PowerEdge R640 is a 1U rack server built around two Intel Xeon Silver 4110 processors running at 2.1 GHz with eight cores each. It ships with 64 GB of DDR4 registered ECC memory and a Dell PERC H730P controller driving two 400 GB SATA SSDs. Dual 750 W platinum power supplies and iDRAC9 Enterprise remote management are included for high‑availability deployments.

Suited for scale‑out workloads

This configuration fits dense virtualisation clusters, database nodes and high‑performance computing jobs that benefit from dual‑socket throughput in a single rack unit. Organisations needing more than two CPUs, larger local storage arrays or GPU acceleration will need a different chassis.

Dual‑socket 8‑core limit

The motherboard supports a maximum of two processors, so the installed pair of 8‑core Xeon Silver 4110 chips already reaches the platform ceiling. Buyers who require higher core counts per node must select a server with a larger socket count.

Questions about this item

What comes in the box and what must I add?

The server ships with two Xeon Silver 4110 processors, 64 GB DDR4 in four 16 GB modules, a PERC H730P controller with battery, two 400 GB SATA SSDs, an X520/I350 quad-port network card, iDRAC9 Enterprise, dual 750 W PSUs, rails and bezel. Extra drives or memory are purchased separately.

Which memory configuration should I choose for this R640?

The system has 24 DDR4 slots and currently holds 64 GB as 4 x 16 GB registered ECC at 2400 MHz. You can expand up to 3 TB by filling the remaining 20 slots with matching DDR4 RDIMMs.

What does the 2.1 GHz base clock mean once the server is running workloads?

Each of the two 8-core Xeon Silver 4110 CPUs runs at 2.1 GHz base and can turbo to 3.0 GHz, giving 16 total cores for parallel tasks such as virtualization or database work.
