Built for virtualisation and databases

The Dell PowerEdge R640 is a 1U rack server designed for business workloads such as virtualisation, databases, backups and application hosting. Two Intel Xeon Gold 6148 processors deliver 40 cores at 2.40GHz, while 192GB of DDR4 memory supports multiple virtual machines and data-intensive services.

Suits consolidation projects.

This configuration fits teams consolidating workloads onto fewer physical hosts where core count and memory capacity matter. Buyers who need dedicated GPU acceleration for rendering or AI training should look elsewhere because only integrated graphics are present.

Ten 2.5-inch bays with eight NVMe-capable slots

The front chassis provides ten 2.5-inch drive bays, eight of which support NVMe devices, and the included H730P controller manages the array. Drives are not supplied, so you select the capacity and media type that match your performance and budget requirements.

Questions about this item

What rack depth does the PowerEdge R640 1U chassis require for mounting?

The server is a standard 1U rackmount unit; verify your cabinet depth accommodates the chassis and rear cable routing.

Which step is often missed when installing drives into the 10x 2.5" bays with the H730P controller?

After inserting drives, you must use the controller BIOS or iDRAC to create a virtual disk before the operating system can see the storage.

What memory type and maximum capacity should I plan for when the 192GB DDR4 installed today needs expansion?

The system uses DDR4 and supports up to 3TB total; add modules in matched sets per processor for best performance.
