Dell PowerEdge R640 40-core rack server

The Dell PowerEdge R640 is a 1U rackmount server system built for business workloads. It runs two Intel Xeon Gold 6148 processors at 2.40GHz, totalling 40 cores across both CPUs. Installed memory is 256GB of DDR4, expandable to 3TB. Storage consists of ten new 2TB SATA SSDs managed by an H730P controller in ten 2.5-inch bays, eight of which are NVMe capable.

Suited for virtualization and database hosts.

This server suits teams that need dense CPU capacity for virtualization, file storage, databases, backups or application hosting. The integrated graphics and lack of dedicated GPU support mean it does not fit workloads that require hardware-accelerated rendering, AI training or video transcoding. Buyers who need PCIe add-in cards for specialised accelerators should look at a different chassis.

Ten 2.5-inch drive bays

The single specification that decides fit is the front bay layout: ten 2.5-inch bays with an H730P RAID controller, eight of which accept NVMe drives. This density sets the maximum local storage count and the mix of SATA and NVMe devices you can install. Confirm that your cabling, backplane and drive carrier kit match this bay population before ordering.

Questions about this item

What rack cabinet and rails do I need to install the R640?

The R640 is a rackmount server that fits a standard rack cabinet and requires compatible rails for secure mounting.

Can the H730P controller manage my existing SATA drives alongside the 10 new 2TB SSDs?

The H730P storage controller supports SATA drives so it can manage existing SATA drives together with the 10 new 2TB SATA SSDs installed in the 2.5-inch bays.

How do I verify the 40 cores and 256GB DDR4 are recognised after setup?

Check the system BIOS or operating system to confirm 40 total cores from the 2x 18-core Xeon Gold 6148 processors and 256GB DDR4 memory are detected.
