Ok, I read the article at

Some things to consider was that it had to be on the same subnet using the
same HMC and using virtual storage (such as a SAN). And your lan has to
be on a virtual port.

My first concern was with like/different hardware. Syncing up resource
names can be a hoot. Then I started wondering if this was really such a
big deal anymore. You already have to use virtual ethernet. I do - no
big deal. I really do not use modems anymore so that's not a concern.
Tape drives could be a concern. Stuff like this would take some planning.

At this time I can't see me utilizing it. From what I read it's not
really a HA idea. And since we are finally moving our HA box out of the
same machine room as our primary I do not want to go back to that. We're
not a SAN shop. At least not for the Power 6 stuff (i's and Linux). We
have a NetApp SAN we are going to be upgrading and/or replacing soon, very
soon. That's for our blade centers (all windows stuff).

Might be for you, but I do not see it for us in the foreseeable future.
