Before implementation, we just talk about planning storage for 10G RAC.
We can use one of the following Storage mechanisms for Oracle clusterware component (OCR and Voting Disk):
- OCFS 2
- Raw devices (LVM Logical Volume)
- Third party cluster filesystem such as GPFS or Veritas (CVM Raw Volume)
Note: The minimum required size OCR is 100 MB and Voting Disk is 20 MB
Also we can use one of the following Storage machines for RAC database storage:
- OCFS 2
- ASM
- Raw devices (LVM Logical Volume)
- Third party cluster filesystem such as GPFS or Veritas (CVM Raw Volume)
