I'm experienced with HP-UX on HA, my experience told me that a floating IP
can be used in such cases. I've built clusters with that. So I guess there
should be similar stuff in the Linux cluster software... So you may want to
look at there as a start.

>1. Power supply redundancy is all hardware. For instance the big MB

>power supply--they go to a redundant power supply backplane which has
>the removable power supply boxes in them. The backplane just uses one
>(I think), but can instantly swith to the other if one fails. This
>backplane can also flash lights or make a noise when one fails (just

>I don't know about finding a redundant backplane and power supplies for
>that MB (we couldn't when we ordered), but good luck and please let me
>know if you find any.

>2. Ethernet redundancy for that MB would be setup in Linux, but I don't

>switches that can do it -- nothing like 200Mbs full-duplex!

>Good luck, and if you get the chance, please keep me posted on progress
>(always looking for new ideas).
