Which is the best 40", 41", 42", or 44" Depth Rack for me?

Comparing racks can be a daunting task. Even comparing racks with similar dimensions can be like comparing apples to oranges. In addition to your dimensions requirements, please also take into consideration the rack's cooling capabilities and cooling options, compatibility, load capacity, cable management options, rack accessories, rail mounting, and overall rack expandability. For additional help, please contact our expert sales engineers at 1-866-722-5776.

When selecting the depth of your Server Rack you will want to keep in mind what the deepest piece of equipment you will be putting in it, and then leave a couple of inches behind it for running your cables and power cords. Also please keep in mind that the Usable Rack Depth "rail-to-rail" is typically 2" less then the Actual Rack Depth. Depending on your application, requirements, and space limitations, it may be prudent to go with a slightly deeper server rack to account for both the depth of the latest servers and blades sold as well as providing enough additional room for cable management, power strips and power cords.

40" & 42" are the most common server rack depths for data centers & server rooms.

* For ease in comparison, depth and width are shown here with rounded external rack dimensions. To see the specific dimensions, please view the individual rack page.
