ASM and using more than one diskgroup
Date: Fri, 27 Jun 2008 09:08:53 -0400
I am currently using ASM with 1 production database. are there any reasons why I would consider using more than one diskgroup? This is just an opinion based queston. One reason might be if i want to spread IO on different disks.
I am on a SAN. I have my SAN administrator present me space as follows
Raid Group 1 -> Lun 1-> Linux Partition 1 Raid Group 2 -> Lun 2 -> Linix Partition 2
I can use the different diskgroups to spread out my IO. Or would I want 1 diskgroup and then enable oracle striping and mirroring ?
This design is in contrast to just creating a black box on the SAN where I might get multiple Luns, but I don't know what disks/raid groups they are pointing to.Received on Fri Jun 27 2008 - 08:08:53 CDT
