is also provided for firmware upgrades.

Components

The big power draw is your server room, that’s no secret. However, a number of other
places within your IT infrastructure can save you some watts. You won’t see the huge
numbers adding up like they do in the server room, but every bit helps. Plus, if you are
replicating a setting change across hundreds or even thousands of workstations, those
savings will add up.
