We are currently planning to deploy 18.104.22.168 RAC using Linux 6.x and NetAPP FAS3210
We are planning to use Oracle ASM (using external redundancy) over NFS
The AGGREGATE consist of 24 disks
We are planning to create 6 Flex Volumes and carve out 4 luns from each Flex Volume. We are told that there is a one to one mapping between LUNS and Flex Vols. Is that true?
We are asking because if that's the case, we will have to create 28 Flex Volumes
We also would like to know that when using EXTERNAL redundancy with ASM Disk Groups, does it matter if each DISK GROUP is created using a minimum 4 LUNS (In accordance with Oracle ASM best practices) as opposed to a single LUN?
Thanks in advance for your assistance and guidance
