I got 2 servers (2U) and 4 FAS shelves in my basement right now. Each have redundent PSUs. Each of them have a backplane for the PSU that allows for power to be dynamically and simultaneously switched and load balanced if a PSU fails. I can literally yank a PSU while with the machine is on and plug it back in without issues. >.>
I don't think you are going to get this into a home brew server.
I should have specified more on what I'm doing. This is going into a Colo I'm renting and their will be a UPS already in place. I'l be using a Norco 4220 for a NAS appliance, but this takes standard ATX sized Power Supplies.
I'm trying to acomplish
A. I'm trying to take advantage of the two separate power grid that are on my 24u of rack-space I'm renting.
B. I'd like to have a little fault tolerances with power.
I know they MAKE standard ATX dual redundant PSU's, Its just I'm looking for something less expensive that someone has experience with.http://www.newegg.com/Product/Product.aspx?Item=N82E16817147018
