Dell PowerEdge R640 4LFF dual Xeon server

The Dell PowerEdge R640 is a 1U rack server fitted with two Xeon Silver 4215R processors at 3.2 GHz and 256 GB of DDR4 ECC registered memory. Four 3.5-inch drive bays are served by a PERC H740P RAID controller. Integrated graphics and an iDRAC9 Enterprise licence handle remote management out of the box.

Suits virtualisation hosts

The dual-socket layout and large memory capacity support dense VM deployments or database caching. Buyers who need GPU compute density, more than four 3.5-inch bays or a single-socket platform should look at something else.

Dual Xeon Silver 4215R at 3.2 GHz

Two 8-core Xeon Silver 4215R CPUs deliver sixteen cores at a base frequency of 3.2 GHz with 11 MB cache each. This processor choice fixes the performance ceiling for compute-bound tasks.

Questions about this item

What rack depth does the 36 x 24 x 10 in chassis need?

The chassis is 36 inches deep, so the rack must provide at least that much usable depth plus cable clearance.

Which specific step must be completed before the PERC H740P RAID Controller can present volumes to the operating system?

After inserting the 3.5-inch drives, use the controller BIOS or iDRAC9 to create a virtual disk across the installed drives.

When should the 256 GB DDR4 memory be upgraded to reach the 7.68 TB maximum?

Add DDR4 modules when workloads exceed the installed 256 GB; the system supports up to 7.68 TB across all slots.
