HP DL980 G7 Power redundancy configuration

[i-techcity]

hi there,

I'm looking for the power redundance configuration for the  HP DL980 G7 server with 8 power supply.

Just wonder if the power configuration should be like either way below

e.g.

primary

primary

primary

primary

ups

ups

ups

or

primary

ups

primary

ups

primary

ups

primary

many thanks in advance

We just deployed two DL980 G7 servers.  I made the same inquiry about power redundancy and power cabling to my HP account team.

The answer I got back is that all power supplies connect to a common power bus within the server.  So, in an A-B power topology, four (4) power supplies should connect to power source A, and four (4) should connect to power source B.  It doesn't matter which four (4) power supplies are connected to power source A and which are connected to B.  It just matters that four (4) power supplies are connected to each power source.
