hi Dave.
I wouldn't recommend RAID 0+1 for your implementation. A simple RAID5
setup will do just fine. The performance increase in using RAID 0+1 will
be negligible. The fault tolerance is not an improvement over RAID5. It's
far more expensive to implement.
I implement Exchange servers in environments similar to yours as:
mirror OS (controller 0)
seperate mirror Logs (controller 0)
RAID5 stores (controller 1) minimum four drives, preferably 5 or 6 just to
spread the operations across more spindles.
either a global hot spare and/or a good support contract (I use Gold
support 4x7x24 with Dell)
That's my ideal config anyways. If money is short, combine the OS and
logs, but still keep the stores on their own RAID5. A PE4600 with a split
backplane and drive cage will allow that config. You might have to go to a
PE2600 with a PV220 to do the config above.

Good Afternoon,
I had a question regarding what type of Raid Configuration is most
likely the best to use with an exchange 2003 Server.
I was told a Raid 0+1 is the most practical, but I am unaware how to
layout the disk design. I was wondering if someone can assist with a
solution and how would I set up the array. I know I'm going to use
smaller, faster 15K SCSI drives possibly 36Gb. I want to setup the disk
storage to the best configuration for performance.Thank you.
Brand New DELL PE Server Specs:
Exchange Server 2003
Win3K Server Enterprise Box
4GB Ram
Unknown Hard Drives, Possibly Six 36GB Drives
OS will be mirrored
Transaction logs will be on their own disks
Information store will be on their own disks
Information Store is currently about 2-3 GB with minimal growth in future
