16drives on a 520 means you have at least one 0595 and drives on both
the CEC (with it's sucky 40mb controller) and the 0595 (with a wide
range of controllers).
I would think that any controller at the p7 level would stomp the
ground with those. I'm not so sure on the disk arm side, i keep
reading that a bare min would be 6 arms...
To be able to compare properly you would need to get a rack config, or
at least list the disk controllers and which drives are hooked up to
And check which controller would be on the power7 machine...

I've asked a BP for a quote on a Power 7 to replace our System i 520,
thinking that maybe the 3 year cost wouldn't be much more than the
maintenance alone on the System i. Haven't received the quote yet, so I
don't know if I'm delusional or not.
Anyway, the System i has 16 ~36gb drives at only 20% capacity. IOW we only
have 98gb data on the System i. Isn't the smallest drive available on the
Power 7 larger than that? At a minimum I would want 4 drives, raided, with
a 5th as a hot spare. Any way to tell the performance, disk-wise, of that
system as compared to our current system?
