Edit: My second post for AIXchange. How long did it take for my topics / style to improve? Now we have POWER servers, we do not still have System p machines. I would argue that keeping hardware from failing is still something to worry about.

I am trying to stop a hardware outage from taking down the partitions that I have running on my System p machine. The whole idea of virtualization and consolidation will backfire on me if a hardware issue now takes out four machines instead of one.
As we do this planning, will we take advantage of as much redundancy as we can? Are we making sure that we have different feeds coming from different power sources? Are we setting up multiple fibre paths to our storage-area network and trying to have our multiple fibre cards exist in different I/O drawers? Are we setting up redundant virtual I/O servers so that we can lose one and still keep our client LPARs running with the remaining server? Do we have redundant hardware management consoles set up and functioning?
What other tactics do you utilize to maintain your uptime?
