Tom ,
so we can put this in proper perspective, what prior systems has Power Tech placed in each LPAR?
Not sure  what  throughput stress  testing  application for  security
3 drive RAID sets might be fine for lite workloads. That 4th drive makes tons of difference.

Al:

It's possible that you will have no problem with 3-drive RAID sets.
If you aren't doing major database stuff, you possibly won't notice
it. We're running 3-drive RAID sets on a 4-LPAR 520 and it screams
(compared to the 270 and a couple other systems it replaced, all
with quite a few more drives).

But we're a software house. We aren't running "applications" as such.

Now, running a full Product Build, where 100s of objects are being
created and many programs run through full optimization, still puts
quite a load on. But the throughput improvement is still in the
range of 3000%.

It can depend on your workload.
