Clustering and Virualization on SPARC T4-2 servers

Hi All,

I will shortly be installing and configuring Veritas Cluster Server
6.0 on Solaris 10 U10 for Oracle E-Business Suite on 2 Sun SPARC T4-2
servers. Please suggest:

1. Should I use ZFS for root filesystem or UFS or VxFS?
2. Should I mirror using hardware or software RAID?
3. I will have to use either Oracle VM Server for SPARC or containers?
Which is preferred?
4. I hope there no problems in using Veritas Cluster File System (CFS)
for Oracle Database files. If I configure the application in
non-global zones, I want them available inside the virtualized
environment. The SAN storage will be provided by NetAPP. I also hope I
will not face problems in configuring I/O fencing. Again, should I use
Veritas DMP or Sun MPXIO?
5. The entire storage volumes will be replicated to the DR site using
NetAPP storage based replication.

Best Regards,
Bruce
