Purpose-built virtualization server

The Dell PowerEdge R640 is a 1U rack server equipped with two Intel Xeon Gold 6148 processors, each with 20 cores running at 2.40GHz. This 40-core configuration targets businesses running virtual machines, databases, and application hosting workloads that demand consistent multi-threaded throughput. It ships with 256GB of DDR4 memory installed and supports a maximum capacity of 3TB for future expansion.

Storage density and controller

Ten 2.5-inch drive bays populate the front, eight of which are NVMe capable, all filled with new 1TB SATA SSDs. An integrated H730P storage controller manages the array, simplifying RAID configuration and ongoing drive management. Front-panel LEDs provide at-a-glance status for power, network links, and USB activity without needing to access the rear.

Scaling limit

The system board accepts a maximum of two processors, so the current dual-socket layout represents the full compute ceiling for this chassis. Buyers who need more than 40 cores or more than 3TB of memory must look to a larger platform.

Questions about this item

Does the 10-bay 2.5" backplane on the R640 support NVMe drives, and how many bays are NVMe capable?

Eight of the ten 2.5" bays are NVMe capable; the remaining two bays accept SATA SSDs only.

What physical space and weight should be planned for the R640 in a rack?

The server occupies 1U of rack height and weighs 55 units; allow clearance for front drive access and rear cable routing.

What steps are performed before the R640 ships, and which one is most often missed by self-builders?

Technicians set up the BIOS, configure the H730P controller, build the RAID array, update drivers, and run diagnostics; the array build step is the one most often skipped.
