I'm DBA but not hardware specialist.
We would like to implement RAC on two nodes on windows OS using 11gR2
I'm not familiar with shared storage concepts.
My question is :
1. Must shared storage be implemented as some physical Independent computer with some disk space or can it be just some disk space to which two RAC nodes with HBA cards each has access ?
2. If it can be only disk space how is this sharing realized ? Through Clusterware software and ASM ?
Many thanks in advance.
