Using both controllers in a CL380

[Ayman Altounji]

I'm running SQL2000 on my CL380 and I'm looking for bottlenecks. I have my shared storage split into a 4-drive Raid5 array (data and quorum) and a 2-drive mirror (transaction logs). I'm wondering whether it would be possible to opt out of the redundant controller scenario and have my mirror tied to one controller and the Raid5 array to another. My gut feeling says its not possible, but I'd like to make sure.

Given a total of six drives in the shared storage, what would be the optimum way to distribute quorum, data, and transaction logs? I built the current config thinking about spindles, but my DBA wants to break out controllers.

Thanks!

You can associate RAID set LUNs with CR3500 controllers.

You should do the following:

1. Stop all I/O activity to the shared storage
2. Open the CR3500 configuration utility
3. Right-Click on the LUN for the RAID 1 set
4. Select Properties
5. Change the HOST PORT to 1 (default is 0)
6. Select OK, the controller will restart
7. Repeat steps 3-6 for each LUN of the RAID 1 set

Notes:
1. All the LUNs of a given RAID set must be on the same HOST PORT.
2. HOST PORT 0 is the CR3500 Controller 1 and HOST PORT 1 is CR3500 Controller 2.
