It is supported using Power6 processors with i6.1 as a minimum. I'm researching this exact scenario to migrate my existing Power5 i520 to newer
hardware so that we can look at retiring our ESS. I'll either be using the VIOS to virtualize DS4800 or XIV storage, depending on whether we get the
XIV or not. I'm also pressing to get a newer SVC because our current SVC is way old with 4GB cache and 2Gb ports. DS4800 and XIV have to be
presented through SVC for VIOS to work with it and supply it to i. The new SVC also has 4 internal SSD slots and can use IBM's 146GB SSD drives.
It's a mirrored configuration across SVC's. 1 SSD in each SVC, and you can then add 3 more options as you need more. I would then present a portion
of that SSD to i and balance data across all of my storage with i6.1.1 and use the new dynamic balancing mechanisms being release in Dec.
One thing to consider when supplying virtual devices to anything on POWER is that storage/disk I/O isn't all that CPU intensive, but high network
traffic IS CPU intensive. Funny how that works out. One of IBM's trainers, in a class in Denver, said "..you may need an entire POWER6 core to
service a single gigabit port of continuous traffic if that port is fully utilized at or near 100%." The POWER6 520 and other stand alone servers
have an integrated virtual ethernet or host ethernet access (IVE/HEA) port that can be shared out as hardware without needing to virtualize it under
VIOS. However if you want to be able to dynamically move your partitions to another server those network ports will need to be virtualized under
VIOS to take advantage of live migrations. As far as I know live migrations are still being worked on for the i. Did they get that working yet?

I know for sure that IVM is not on the i - it is in the bladecenter only.
VIOS can run natively on all Power machines, but i'm not sure if
running an IBM i partition under VIOS on a Power 520 would be a
supported scenario.
