Re: Can one have SANs on a P05 system?

[Jim Oberholtzer <midrangel@xxxxxxxxxxxxxxxxx>]

Sure, 64GB is a little small, but remember most of the folks on this size
box don't need that much memory.  My system has partitions for four
releases of IBM i, AIX, and three Linux partitions, plus the two VIOS all
running quite happily.   All SAN boot.  Caveat:  Add the SR-IOV cards to
the mix and 64GB will not be enough, but for a smaller workload, it works
just fine.    If IBM would bump the minimum to 128GB they would most likely
never sell a P10 box again.  Memory and card slots are really the only
reason to get past P05.
