Re: [suse-oracle] Best use of ASM

We are using ASM.  We are not using asmlib, since we didn't want to be tied to Oracle's releases for the kernel modules.

I would highly recommend ASM.  ext3 is garbarge.  If you don't want to use ASM, look at XFS or ext4.

With the 12 disks, I would create 6 RAID 1 luns (hardware RAID) and let Oracle stripe across the 6 disks by creating one ASM disk group.

All of the data go into the one ASM disk group.

Subject: [suse-oracle] Best use of ASM

I am in the process of building a new server and considering using ASM. The configuration is as follows:

2 disks - RAID 1 - SLES11/Oracle 11gR2
12 disks on a raid controller to be used for Oracle.

Traditionally I have used RAID 10 or RAID 1 depending of type of files being stored on the logical disk. Data on RAID 10, control, redo, and archive on RAID 1.

How would you divide up the 12 disks between control, redo, data, and FRA? Would you use hardware RAID instead of the built-in Oracle mirroring and striping?

There doesn't seem to be any good documentation out there to give best practices relating to using hardware RAID vs ASM redundancy.

Thanks,
Stacy
