RE: Downgrade from RAID6 to RAID5

Don,

Since Larry said this:

Performance improvement is there yes as you also remove some reads along
with the extra writes but won't rock your world.

I thought I would ask: Are you doing journalling? If so, are you using
5770SS1 42 5117 HA Journal Performance
If not, then I would HIGHLY recommend it.

You mentioned month end. This is exactly why we were hurting also. We
tried moving from spinning disks to SSD's and really did not get the bang
for the buck.
Everything here is journaled as a requirement of our HA software.
Adding option 42 was a serious game changer.

Try a 70 day try-and-buy. Put it on the weekend before your next month
end. Along with the latest PTFs (always a good idea when adding new
options). 70 days should get you through two, possibly 3, month ends.
Hence the reason to not install it too early.
He who signs the checks couldn't wait to sign that check after our lack of
improvement with SSD's.

Downtime due to month end processing was our biggest outage. Saves,
upgrades, etc were easily handled with out HA software.
