The picture above is a "portable" air conditioner. This particular one is rated to cool 17000 btu/hr and is pretty much the largest air conditioner you can run off a standard 20A circuit (it pulls 16A when running). It's one of two (the second one is larger) attempting to keep our second server room cool.
While we had planned on just renting this particular unit until the permanent AC system was installed, it became obvious quite quickly that planning and permitting would extend the rental past the point where it made sense to just buy the thing. We now own two of these (the other requires a 30A circuit), and will hopefully never need to rent one again.
That said, anyone that runs a server room should know where to rent one of these, how long it would take to get it delivered, and how it can be paid for. Our local provider (where we both rented and purchased our units) is Atlas Sales and Rentals. Great guys if you need such a thing in and around Silicon Valley.
I was in need of a bunch of specific lengths of power cables to clean up the wiring on one of our racks. I asked my salesman at CDW for "normal PC power cords to go from a typical wall outlet to a typical PC power supply in lengths of 1, 2, 3, and 4 ft".
Apparently that wasn't clear as I needed as I was presented with a quote for not what I was seeking. A little searching (and questioning of my engineer brother), and I learned that I sought NEMA 5-15 plug to IEC c13 cords. And in case you need to figure out the names of a power connector you find on the wall or on a piece of computer equipment, checkout, Wikipedia's pages NEMA and
IEC connectors.
