More info please Hamid, folks on Comparison between CFS , ASM in terms of what 
made you choose CFS over ASM, Performance, scalability, availability, 
migration, ease of use, backups, need for training, nature of outages on CFS 

Any Docs / Links?

I can speak for the CFS as we are running one from Veritas. Your admin should 
be properly trained otherwise you may see outages during business hours.


Additionally does ASM administration need additional Skill Set / Training 
versus administration on Cluster File System(CFS), for RAC?
If so, in what context?

For subsequent RAC Deployment in ver 10gR2, A Banking customer needs to take a 
decision on use of Cluster file system versus ASM?

Prima-facie, How do the 2 compare in terms of Performance, scalability, 
availability, migration, ease of use, backups, need for training etc.

Any Docs, Links will help.

Currently Production Deployment info:-

 *   NON-RAC with Oracle ver 9.2,
 *   Solaris 10.
 *   Database size if 5 TB approx.
 *   Daily peak load of 20,000 Concurrent sessions connecting to the Database 
via Shared Servers (MTS).
 *   Database exists on the default Unix File system (UFS),
 *   Machine - SF25K SUN Server.
 *   Storage Box - Sun Store Edge 9980 V
