Thanks Dimitre for the details. So does it means that having 4 Disks of 512M in each failure group or One disk of 2G is same in this scenario. e.g Failure group 1==> 1disk of 2G or 1G vs 4 disk of 512M Failure group 2==> 1disk of 2G or 1G vs 4 disk of 512M Failure group 3==> 1disk of 2G or 1G vs 4 disk of 512M Trying to understand if multiple disk in Filure group for OCRVote can provide any additional benefits beside space.

It provides the same availability, but more space. So the question is do you need the space provided by the 5 disk in that DG. Dimitre -- //www.freelists.org/webpage/oracle-l
