Default dbspace planning - 01-21-2011 , 11:12 AM






Hello,

I have only 4-300GB SAS 10K RPM drives that are mirrored across 2 channels. I'm using RAW devices.

Any suggestions as to optimal dbspace layout in this IDS 11.7UC1GE instance on RHEL5.5 32-bit for OLTP?

I'm planning layout below:

disk 1. rootdbspace, phys log, logical log
disk 2. data1 (4 chunks 5GB/chunk)
disk 3. data1 (4 chunks 5GB/chunk)
disk 4. tempdb1, tempdb2

OR

disk 1. rootdbspace, phys log, logical log
disk 2. data1 (1 chunk 20GB)
disk 3. data2 (1 chunk 20GB)
disk 4. tempdb1, tempdb2

Thanks,
June Nebab

My experience with direct-attached SCSI-3 drives has been that a single
large chunk performs slightly better that multiple small chunks.
