And, with a bit of forward thinking, allows for easy upgrade too....
One of the advantages of these modular PODs is their relative ease and quickness of installation. If installed outdoors, provide power, communications and if required cooling, drop it in and you are done.
IF you did your initial planning correctly, you installed the necessary connections for a second location at the same time. When it is time to "upgrade" bring in the new container, connect it, and power it up. Move everything from old to new, and haul away the old one, thus freeing up the old space for the expected (future) replacement. Much better than dealing with replacing individual boxes in racks.
