Based on my read on IBM's technology you have storage that can not be used with RAC.

For RAC you must have clusterware that supports a shared file system. This does not meet shared storage where multiple users share the same space ... but rather complete sharing of files where multiple users can simultaneously open, read, write, and close the exact same files.

The cost of IBM's clusteware is quite high. I'd suggest, unless you have information I don't that you talk to NetApps or someone else selling the correct hardware for RAC.
