We have 36 4326's in 2 RAID Sets and we just added 5 4328's in a third
RAID set. Our controllers were maxed out at 18 drives each, the new
drives work fine . The iSeries balanced the drives just fine.

Subject: Disk Upgrade

We are in need of upgrading our disk space. Below is a snapshot of our
current disk configuration.
Can I just buy a coupe of 140gig 4328 drives and replace the 4326 drives
with them?
I know I will have to stop RAID and restart and all that, but I was
wondering if it will work (and is advisable) with mixed sized drives in
the
same pool.
