RAID capabilities are not the job of the filesystem (any filesystem).

Any SAN has hardware RAID, look into the firmware.

There is also linux software RAID, that could be used with cheap hardware and 
iSCSI to make a test environment.  Then again, if it's a test environment you 
don't quite need RAID.

But for anything serious to keep your Oracle datafiles, you have hardware RAID 
in the storage firmware.

The filesystem comes on top of that.
