I may be asking the obvious here but who dedicates their Oracle->Filer traffic to just *one* Filer?  IE: That Filer *ONLY* handles Oracle->NFS->Filer traffic.
 
Our CIFS traffic has grown significantly since we bought our FAS940 and I'm now dubious about mixing CIFS/Desktop services with Enterprise critical Oracle services.
 
Currently we have a few small DB's (read-only) on the Filer but are moving to step things up over the next year with Regards to Oracle. (we are looking at RAC).
 
So:  Would ALAWYS or SOMETIMES or NEVER mix Oracle and Desktop Filer services on one filer?  :-)
