We just installed a new Oracle 10 Rac environment using to P550 serves with 8 gig of Ram. We have two internal disks mirrored and the rest are IBM DS4800 SAN disks. We currently have 6 databases in the rac environment. Problem we are having is that everytime we run a copy command or zip command we start paging. Hdisk0 and Hdisk1 go up to 100%. I was wondering a few things.

1. Should paging space be mirrored ?
2. If anyone has had this problem with Rac environment and what vio parameters did they use to maybe better tune the environment.
3. Just wondering if we put the OS disk on the SAN would it make difference.

Any help is appreciated Thanks
