Best config for Sql 2008 x64 on Windows 2003 x64
I need some help building out this system.
I built it out with two 8 drive ADG Logical drives.
I put Data on one logical drive and OS,Logs,Backup on the other.
It was my understanding that ADG would be faster than Raid 10, regardless I didn't have enough drive space to do raid 10 at the time.
I plan to move an existing MSA 500 with 14 146 gig 15K drives to this machine, with a dedicated controller (the one that comes with the msa500.
Is it best to create a new ADG Logical drive or a raid 10 drive. What should I put on that drive (data or logs or both?
Should I Reconfig the non OS partition back to raid 10?
BTW, all the sas drives are DP.
Both P400's have 512 BBWC
The MSA 500 has 512 BBWC
My perfmon shows low use of the current data logical drive, but high use of the log logical drive.

In your case I would put the
OS on a RAID 1 (2 drive set) separate from the database.
Make a RAID 10 Logical for DATA
Make another RAID 10 Set for Logs with lower stripe sizes.
Take the OS storage and Swap out from your DB storage.

I can't afford the down time to rebuild the OS so Array 0 can't be changed.
Array 1 can be changed since I can be down long enougth to move data/logs around.
Array 2 will be the new 14 Drive U320 Array.
Array 0 - 8 drive ADG SAS has:
C: OS
D: SQL
E: Backups
J: Logs
I was planning to conbine E: and J: as a new larger E: for just backups.
Array 1 - 8 Drive ADG SAS has:
F: Data
G: Data
H: just some extra space
Array 2 will be a new 14 Drive U320 array on the MSA 500
Should this be ADG or Raid 10 Which will offer the most safety and speed.
Should I put logs or data on the new Array 2?
It will be a waste of space to use it for logs, but that would seem to offer the best performance.

Thanks DJDecay, that helps me understand a lot, and I'll make most of those changes.
I'll create array 2 as Raid 10 and recreate array 1 as Raid 10 and I'll put logs and data first on each.
My main database is 35 gigs, whats the recommended block size? I usually leave this at default since I don't know what's best. It seems to me it should be quite large if the data is 35 gigs and I want to place it on the new array 2. The other 10 DB's are 1-4 gigs each
