Single-socket rack server for dense compute

The Dell PowerEdge R640 in a 4LFF chassis ships with one Xeon Gold 6134 running at 3.2 GHz and 256 GB of DDR4 ECC registered memory across sixteen 16 GB modules. A PERC H740P RAID controller and a dual-port 10 GbE 562T adapter are installed, while two 750 W power supplies provide redundancy. The system supports a second processor and up to 7.68 TB of RAM for future growth.

Suits workloads that fit four 3.5-inch bays

This configuration targets virtualisation hosts, database nodes or batch clusters that can operate within four SATA drive slots and 256 GB of memory. Buyers who need more than four 3.5-inch drive bays, require two processors immediately, or depend on a GPU for compute acceleration should consider other platforms.

Four 3.5-inch drive bays define storage capacity

The chassis accepts exactly four 3.5-inch SATA drives and no additional internal bays are present. If the application demands more than four spinning disks or solid-state drives, this server cannot meet that requirement without external enclosures.

Questions about this item

What drives and rails come with the R640 and what must I add?

The chassis has four 3.5-inch bays but no drives are installed; a rail kit is available on request.

Should I pick the single 6134 or add a second processor?

One Xeon Gold 6134 at 3.2GHz with eight cores is installed; the board supports two, so add a second only if your workload needs more threads.

How does the 256GB DDR4 ECC registered memory perform in this server?

Sixteen 16GB modules fill the installed slots, delivering 256GB of error-correcting DDR4 that runs at the platform's rated speed for stable virtualization or database work.
