Are you saying you have two redundant PDUs? If so, feeding each power cord from seperate PDUs is a more reliable approach to powering dual corded equipment. If you only have one PDU, then the next best thing is to feed each power cord with a different circuit. As for which phase to use, it absolutely doesn't matter as long as the three phases are loaded in a balanced manner.

Just a quick sinmple question!
What are the issues with running dual fed servers from PDUs, one fed from one phase and the other fed from a second phase?
Thanks in advance.
