Some more information (sorry, should have included earlier): Support section excerpt from SAP Note: RAC 11.2.0.3/4 (Solaris 10 and Solaris 11, hardware manufacturer-independent configuration) - Oracle Clusterware 11.2.0.3/4 + ASM/ACFS 11.2.0.3/4 - Veritas Storage Foundation for Oracle RAC 5.x / 6.x RAC (9.2/10.2/11.2.0.2) on Sun hardware: - Oracle Solaris Cluster 3.x (x is 2 or higher) + Oracle Sun Unified Storage/Oracle Sun ZFS Storage Appliance with Direct NFS or - Sun Cluster 3.x (x is 2 or higher)+ Sun QFS 4.x (x is 5 or higher) or - Veritas Storage Foundation for Oracle RAC 4.x / 5.x My question really is to understand if Oracle supports RAC 11.2.0.3 on Oracle Sun Unified Storage/Oracle Sun ZFS Storage Appliance with Direct NFS. Is there an Oracle note saying YES or NO... Thanks in advance.
