Have you seen/implemented EFSCG for Oracle databases ?

If you want a single file served by multiple scalable NAS heads without
replication overhead, you have to use the EFS.CG. It is the
only product out there that does it.
 
I found the HP gateway with Google pretty quickly:

what does "NFS of CFS" mean?  Exporting a CFS? Yeah, that's
being done. It's called the StorageWorks Enterprise File Server Clustered Gateway
by HP. Up to 16 nodes of scalable NFS with transparent NFS client failover in the
event a NAS head should fail. And when I say transparent, I mean it. Oracle
CRS, and database processes have no idea that the NAS head serviing up their
files has died.  Not exactly the typical filer experience. Yeah, I know you can "cluster"
and replicate filers. The HP EFS/CG requires no replication for this high availability/
scalability. Want to know how I know ?
