Built for virtualization and database workloads

The Dell PowerEdge R640 delivers 40 cores across two Xeon Gold 6254 processors running at 3.10GHz. It targets businesses running file storage, virtualization, databases, backups and application hosting. Buyers who need GPU acceleration or single-threaded clock speeds above 3.10GHz should look elsewhere.

HBA330 controller and iDRAC Enterprise included

The HBA330 storage controller manages the ten 2.5-inch drive bays, eight of which support NVMe drives. iDRAC Enterprise provides remote management for monitoring and maintenance without physical access. No operating system or storage drives are supplied, so you must provision both.

Rackmount form factor simplifies deployment

The 60-weight chassis fits standard racks and uses integrated graphics, eliminating discrete GPU clearance concerns. Installation typically involves seating processors, populating DDR4 memory up to 3TB, adding drives and connecting power. Missing drive caddies or incompatible drive heights are the most common issues.

Questions about this item

Will the 512GB DDR4 memory need upgrading for heavier virtualization workloads?

The system supports up to 3TB of DDR4 across its slots, so the installed 512GB can be expanded later if workloads grow.

What limits sustained compute performance on the dual Xeon Gold 6254 CPUs?

Each Gold 6254 has 24 cores at 3.10GHz, giving 40 total cores; thermal and power envelopes of the 1U chassis become the practical ceiling under continuous load.

How loud and hot does the R640 get when running all day with ten NVMe drives?

Ten 2.5-inch bays and dual 6254 processors draw significant power, so the high-speed fans needed for cooling produce noticeable noise in a rack row.
