Server racks are important as they provide a space for vital equipment that is crucial for your organization. If you select the right server rack, you will keep your equipment cool, your power running, and your downtime minimized. The internal height of server rack is measured from the highest location of any side rail to the bottom chassis; the inside depth of a server rack is measured from the insides of front and rear doors; and inside width is measured one side panel to the other one. Make sure that the rack external dimensions will fit in the floor space planned for it. Also, make sure to check that it will be able to safely position through all doorways.
