Rack Server with Dual Xeon Silver 4108

The Dell PowerEdge R640 is a 1U rack server equipped with two Intel Xeon Silver 4108 processors running at 1.8 GHz. It ships with 256 GB of DDR4 ECC registered memory and a PERC H740P RAID controller. The 4LFF chassis supports up to four 3.5-inch SATA drives, which are not included.

Installation Notes and Common Issues

The unit includes two 750 W power supplies and a 10 GbE 2-port 562T adapter. Rails are available on request but not fitted by default. Drive caddies for the 3.5-inch bays must be sourced separately. Buyers sometimes assume drives or rails are included and delay deployment.

Pre-Order Compatibility Checks

Verify that your rack provides at least 36 inches of depth and can support the 40 lb weight. Confirm you have suitable 3.5-inch SATA drives and compatible caddies for the four-bay backplane. Ensure your network infrastructure can use the installed 10 GbE adapter and that iDRAC9 Enterprise licensing matches your management needs.

Questions about this item

How can I verify the PERC H740P RAID controller is recognised after power-on?

During POST the controller BIOS will appear and list the 4 x 3.5-inch bays; iDRAC9 Enterprise then shows the controller status and firmware version in the web interface.

Which components ship inside the chassis and which must be ordered separately?

The unit includes 2 x Xeon Silver 4108 CPUs, 256 GB DDR4 ECC registered memory, PERC H740P RAID controller, dual 750 W power supplies and a 10 GbE 2-port 562T adapter; 3.5-inch drives and rail kit are not included.

Should I choose the 256 GB DDR4 configuration or plan for the 7.68 TB maximum capacity?

Start with the installed 256 GB DDR4 if current workloads fit; the board supports up to 7.68 TB so you can add modules later without replacing the CPUs or chassis.
