Dell PowerEdge r640: Specs and Rack Compatibility


The PowerEdge R640 was released in 2017 and stood out for being well suited for a variety of users. Of course, there are many servers that accomplish this same thing, but the R640 was particularly versatile for its 1U form factor. 

In 2020, the base model sells on Dell’s website for $1,679 but can be configured into a $10,000+ server with different configurations. Aftermarket prices are still relatively high and listings mostly consist of professional resellers.

Rails allow for the most efficient use of space when mounting servers. RackSolutions specifically designed a fixed rail kit to fit the shoulder screws of the PowerEdge R640.

Here’s a guide on how to mount the rail:


Universal rails that have a height of 1U and support up to 29 inches of depth will be compatible with the PE R640. A benefit of these is the ability to re-use them for different servers or future upgrades. Plus, it’s easy to slide your server in and out of them for maintenance.
