IBM i on JS21 blade?

I just got a new toy, a dual 970MP 2,7Ghz, 8Gb Ram, 2x146Gb SAS and
Infiniband (not like i have the hardware for it) blade.
I was wondering, is there a way to install IBM i on it? googling
around led me to believe it supports VIOS but that was as far as i got
yet.
I have a redbook on implementing IBM i on a JS22 blade but that one is
Power6 and i believe this is Power5 (if that, i'm not sure if it is
POWER por just PPC).
This is my first time doing POWER on blades so i'm in a foggy state.
If i dont find anything conclusive i'll just pop the AIX installation
media but i would rather learn VIOS and, if possible, LPAR the blade
and get on the VIOS craze.

Thanks in advance!
