Running 9.2.0.8 (still) on HP-UX 11.11
2TB database Used for OLTP and reporting New SAN is a Hitachi 5TB AMS2100

It seems that these days the simple guidelines for configuring a large Oracle database on a SAN is to simply configure the SAN with a one megabyte stripe width across all disks (2 x 8 disks plus one spare). And, to use a cache block size which is the same size as the Oracle DB_BLOCK_SIZE which is 8192 (8kB)?

All redo logs, archive logs, datafiles and tempfiles would be on the same mountpoint across the 1MB stripe.

We also plan to use RAID 1+0

Is this configuration in the right ball park?

Any suggestions are welcome.

I took the 1MB stripe width size from the following document. Deploying, Managing, and Administering the Oracle Internet Platform Optimal Storage Configuration Made Easy

Which states:
1) Stripe all files across all disks using a one megabyte stripe width.
2) Mirror Data for high availability. Received on Wed Jun 23 2010 - 00:39:45 CDT
