Veritas CFS or QFS ? Which for High Hybrid Transaction Load Benchmark on RAC with Solaris 10/Oracle 10g ?

Folks  

For an upcoming High Hybrid Transaction Load Benchmark on RAC with Solaris 10/Oracle 10g, need to define the File system setup  

Qs Is QFS Certified for Solaris 10/Oracle RAC 10g?

Qs If certified, Is QFS being used at Large Production RAC Sites

Qs Which is advisable - Veritas CFS(SFRAC 4.1) or QFS ?  

Any Docs, Links, advisable Books for the same please?  

RAW is being considered only as a last resort & ASM being avoided for now as it is still seemingly NEW & probably NOT so much tried & tested as yet with High Load Production sites.  

Config info:-

Approx 20,000 Concurrent OLTP sessions will be spawned

Num of Database Server Nodes = 4

Each DB Server Node = 28 CPUs

Oracle Shared Servers will be used

DB Size = 4 TB  

Will provide any Clarifications, Thanks indeed.
