DELL PowerEdge R640 SFF server

This 1U rackmount server delivers dual Intel Xeon Gold 6136 processors at 3.00GHz with twelve cores each. It ships with 48GB of DDR4 memory and six 512GB SSDs behind an H740P controller. The chassis provides ten 2.5-inch drive bays and front LEDs for power, Ethernet and USB status. The unit weighs 60 units and arrives without an operating system.

Suited for virtualisation and database hosts

The dual-processor layout and six SSDs give a solid base for running multiple virtual machines, file services or backup targets. Organisations that need more than 48GB of RAM or additional drive bays should consider a larger chassis. Buyers who require a pre-installed operating system or GPU acceleration will need to look elsewhere because this system uses integrated graphics and ships with no OS.

3TB maximum DDR4 capacity

The platform supports up to 3TB of DDR4 memory across its DIMM slots, so the installed 48GB can be expanded significantly as workloads grow. This ceiling is the key figure for deciding whether the server can meet future memory demands.

Questions about this item

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

The server is a 1U rackmount unit designed for standard four-post cabinets; allow enough depth for rear cabling and the 60 kg weight when fully populated.

How are the 2.5-inch drives and H740P controller installed, and what step is often missed?

Slide the six 512 GB SSDs into the front 10-bay backplane, seat the H740P in its dedicated internal slot, then create the virtual disks in the controller BIOS before installing an operating system.

Which memory modules are used when expanding beyond the installed 48 GB DDR4?

Add DDR4 RDIMMs or LRDIMMs up to the 3 TB maximum; populate slots per the CPU1/CPU2 population rules in the service manual for optimal performance.
