Network Appliance is working closely with Rational to fully test the procedures and risks for putting the VOB database on the filer. As has been mentioned, putting the various storage pools has always worked and many customers use this to great advantage.
Until the move of Network Appliance into the database space, putting the VOB database on the filer was considered risky. Now that both Oracle and Sybase have certified NetApp, it is just a matter of testing, documentation, and time before Rational provides similar certification since theirs is just a modified Raima database anyway.
Some discussion on this topic has already taken place on the Clearcase Users Group discussion groups (CCIUG). If you can, I would suggest accessing those archives for the last 2 months to see where this discussion has gone on that forum and get firsthand Rational's response and plans.

Hi,
We are just starting to deploy ClearCase...
I have been speaking to engineers at Network Applications who assured me that it is possible to create the WHOLE of a ClearCase VOB (including the db) on a NetApp filer (and any other NFS filer for that matter). Since Rational told me this was not possible, I got curious and tried it anyway. It worked! Has anybody else here tried this configuration? Had any problems?
According to the ClearCase docs, if you can snapshot a complete VOB (as on a Toaster) then it is not necessary to lock it prior to backup (though some disk may be lost to empty containers if you restore from it). Anybody tried/trust this or would you advise against it?
Potentially this could make our backup scheme MUCH simpler.
