I was promoted to datacenter design group and my part is to provide input for power distribution unit. What is the best place to stat to start?. I was looking at some of the APC products and it seemer to ver very relaible and seen some good reviews on it. They have Stationary PDUs, Rack PDUs and Rack Automatic Transfer Switches. What I am wondering is what is the suitable products to mange 5-6 racks.

Thank You
Steve
