Power Distribution in a Datacenter?

d00dman asks: "I work for a colocation reseller. We don't own our datacenter, we lease cage space and with it we get an array of 30amp and 15amp power circuits. My problem is, inside of the cage we need to do our own power distribution. We have around 50 hosts in the facility, and are growing quickly. We need to add another 20 or so hosts in coming month. We are looking for a simple, scalable, and even power distribution method. As always, money IS an object. Right now we have a group of UPS's with power strips plugged into each. While this was sufficient for as many as 30 hosts, its starting to become a bit of a mess. Does anyone have any advice to offer...any creative tricks?"
