RAC on Windows with NAS
Hi,
I'm working on installing a 11.2.0.3 2-node RAC on Windows 2008R2 64bit, with an EMC NAS for shared storage.
From my research, this configuration is possible through
1) iSCSI (MOS note ID 1054027.1)
or
2) Direct NFS
Network attached storage (NAS) systems use a network file system (NFS) to access data. You can store Oracle RAC data files and recovery files on a supported NAS server using the Oracle Direct NFS client. (Grid Infrastructure Installation Guide)
or
3) ASM
You can place voting disks and OCR files either in an Oracle ASM disk group, or on a cluster file system.
Oracle recommends that you choose Oracle ASM as the shared storage option for the database data files and recovery files.
Can/should the above be used in combination with each other? Please correct me if I'm wrong, but is iSCSI the only means of sharing the OCR/voting disk files? Perhaps my confusion comes from a misunderstanding of each options specific functionality.
