*Subject:* Re: Disk configuration in new server
Like other disk configurations, it depends on what you're using RAID6 for,
and the hardware (primarily the controller) that is supporting it.
Your storage controller can make or break a RAID configuration by how it
manages reads or writes
be faster overall than
RAID 5?

You're running into the age old question:

Now pick two of those. Just judging by your description of overall
utilization, you're probably not going to see much difference in
performance whether you choose RAID 5

3 array's on one controller. And they say the disk i/o on exchange 2010
is not nearly as important as previous versions.
From: Evan Brastow
I have never used the p410i Smart Array Controller specified for that
server, but every other Smart Array Controller I've used allows you to
create multiple arrays and multiple logical drives. If the size of the
server is adequate for your environment, I can't imagine that you'd have any
trouble
I'd say run mirrors for all volumes except the data (information store) if
your IS size is already large ...
but best decision will be based on your current disk usage and projected
growth. Depending on your backup schedule and traffic volume, your log
files may require large storage too.

No RAID5 for me where Exchange is concerned.
