1.) Running Oracle Real Application Clusters on Oracle VM Server for SPARC (PDF)

http://www.oracle.com/technetwork/server-storage/vm/overview/index.html
Under
Oracle VM Server for SPARC Technical White Papers

Which is a very through White Paper.
This suggests direct I/O and defines domain types and how you can
create an I/O domain or root domain and assign a pcie bus directly to that
guest domain It's fairly detailed.

The number of I/O domains is dependent on the system type and hba's need to
be supported hba's as well.

2.)
Next I also review
Oracle VM Server for SPARC Best Practices
http://www.oracle.com/technetwork/server-storage/vm/ovmsparc-best-practices-2334546.pdf

Specifically you may want to review the sections on I/O.

3.)
Make sure HBA's are supported for Direct I/O.

Review:
1325454.1 Oracle VM Server for SPARC PCIe Direct I/O and SR-IOV Features

4.) if needed
There are also other Best Practice Documents for Oracle VM for Sparc

5.) Be sure that you also go over any best practices for ASM disks. I've seen several customers not follow ASM best practices and
overwrite their disk labels

Oracle Solaris logging "primary label corrupt; using backup" or "Corrupt Label; wrong magic number" in Oracle ASM environment ( Doc ID 1532506.1 )
and

ASM Technical Best Practices For 10g and 11gR1 Release ( Doc ID 265633.1 )
