I just wanted to get some sort of idea on how power should be distributed on Equallogic PS6510.

There are three PSU at the back of the unit.

PSU1 plugs in to PDU A

PSU2 plugs in to PDU B

PSU3 plugs in to PDU A or B

Problem is that 6510 requires power from at least two of these PSU's at all times to work.

If we have two of these plugged in to the same PDU and we were to lose power to this PDU, it will take PS6510 down!

Where is the redundancy in this? Is there any kind of solution to this?

Thanks.
