Targeted Server Build

The Dell PowerEdge R640 is a 1U rack-mount server system designed for data-centre deployment. It ships with two Intel Xeon Silver 4208 processors running at 2.1GHz and 32GB of DDR4 ECC registered memory installed across two modules. The chassis supports up to four 3.5-inch drive bays and includes a PERC H740P RAID controller for storage management.

Fit and Gaps

This configuration suits teams building virtualisation hosts or database nodes that need dual-socket compute and hardware RAID in a compact 1U form factor. Buyers who need drives included, GPU acceleration, or more than two processors should look at alternative platforms. The unit arrives without storage media, so separate drive procurement is required.

Deciding Specification

The installed CPU count is fixed at the maximum of two Xeon Silver 4208 processors, so the processing ceiling is set at purchase. Memory can scale to 7.68TB using DDR4 modules, and the PERC H740P controller handles the RAID layer for the four 3.5-inch SATA bays. Remote administration is provided through iDRAC9 with an Enterprise licence.

Questions about this item

What drive bays and interface does the R640 chassis provide for adding my own storage?

The chassis has four 3.5-inch bays that connect to the PERC H740P controller over SATA.

Will the installed PERC H740P RAID controller recognise older SATA drives I want to reuse?

Yes, the H740P supports SATA drives so existing 3.5-inch disks can be added and configured in RAID.

How can I confirm the two Xeon Silver 4208 processors and 32 GB DDR4 are detected after first boot?

Open the iDRAC9 web interface or enter the BIOS; both will show two CPUs at 2.1 GHz and 32 GB of DDR4 memory.
