Yes I have it running at several clients. Assuming that disk busy was not high before ( meaning < 20% ) and you have the newer controller cards ( SAS ) you should not see a performance difference. We also turn on hot spare.

Any of your systems configured for RAID 6 protection?
Noticed any discernible performance decrease with RAID 6 compared to
what you had with RAID 5?

Or do you just use RAID 5 on yours?
We configured our high-availability POWER 7 8202 for RAID 6.

I am considering possibility of RAID 6 on our production POWER 7 8202.
Currently it is RAID 5.
