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
etc.
Any Docs / Links?
Cheers

Vivek,
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.

Folks
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.
