Dell PowerEdge R640 10-bay rack server

The Dell PowerEdge R640 is a 1U rackmount server built for business workloads such as virtualization, databases, file storage, backups and application hosting. It ships with two Intel Xeon Gold 6148 processors running at 2.40 GHz, 256 GB of DDR4 memory and an H730P storage controller. Ten 2.5-inch drive bays are populated with 1 TB SATA SSDs.

Dual 24-core Xeon Gold 6148 upgrade

The system installs two processors, each with 24 cores for a total of 40 cores, reaching the platform maximum of two sockets. This configuration suits organisations moving from single-socket or lower-core-count servers that need more parallel threads for virtual machines or data-heavy applications. The jump is worth it when current hosts saturate CPU resources during peak loads.

Compatibility checklist before ordering

Verify that your rack provides a 1U slot and that power distribution can support the unit weight of 60. Confirm the H730P controller matches your existing storage topology and that DDR4 memory modules align with any planned expansion up to the 3 TB ceiling. Ensure operating-system licences are available since none is included.
