Rackmount Server for Virtualisation

The Dell PowerEdge R640 is a 1U rackmount server built for business workloads such as virtualisation, databases, file storage and application hosting. Two Intel Xeon Gold 6148 processors deliver 40 cores at 2.40 GHz, and 256 GB of DDR4 memory supports multiple services and virtual machines. Eight 2.5-inch drive bays and an H730P storage controller provide flexible internal storage capacity.

Suited for Dense Compute, Not GPU or Tower Builds

This platform suits organisations that need high core counts and large memory in a compact rack footprint for virtualised environments or data-intensive applications. Buyers who require GPU acceleration, direct-attached storage using protocols not listed here, or a smaller tower form factor should evaluate other platforms. The integrated graphics and lack of an operating system also mean it is not a ready-to-run workstation.

Eight 2.5-Inch Bays Define Storage Flexibility

The single specification that decides fit is the eight 2.5-inch drive bays paired with the H730P controller, which determines how many drives you can install and what RAID levels are supported. Drives are not included, so you select capacity and type to match workload demands. Maximum memory capacity reaches 3 TB across the available slots.

Questions about this item

Does the R640 ship with drives or do I need to buy 2.5" drives separately?

The server includes eight 2.5" drive trays and an H730P controller, but no drives are installed — you select and add the capacity and type you need.

Is the 40-core count from one CPU or the pair of Xeon Gold 6148 processors?

Each Gold 6148 has 18 cores, so the two installed CPUs deliver 36 physical cores; the 40-core figure in the title reflects the total thread count.

What does 256GB DDR4 mean for the number of virtual machines I can run?

With 256GB installed and a 3TB maximum, you can host many memory-heavy VMs today and still have headroom to add more modules later.
