Oracle has released Oracle VM Server for SPARC 3.2 packages for Solaris 10 control domains. The package can be downloaded from http://www.oracle.com/technetwork/server-storage/vm/downloads/index.html#OVMSPARC
Not all of the performance and functional enhancements of Oracle VM Server for SPARC 3.2 are available when used with Solaris 10. Oracle recommends that customers use Solaris 11, especially for the control domain, service and I/O domains. Note that future Oracle VM Server for SPARC releases will no longer support the
running of the Oracle Solaris 10 OS in control domains. You can continue
to run the Oracle Solaris 10 OS in guest domains, root domains, and I/O
domains when using future releases. Solaris 10 guest domains can be used with Solaris 11 control domains, allowing interoperability while moving to Solaris 11. For additional details, please see the Release Notes.

Multipath groups are arranged in an active/standby pair of connections to the same physical media. In case of a path or service domain failure, I/O activity continues on a surviving path. This is also helpful for rolling upgrades: a service domain can be rebooted for an upgrade, and virtual disk I/O continues without interruption. That's important for continuous availability while upgrading system software.
A previous limitation was that you could not determine by commands which path was active, and you couldn't force activity onto a selected path. That meant that all the I/O for multiple virtual disks went (typically) to the primary path instead of being load balanced across service domains and HBAs. You could deduce which service domains were actively doing disk I/O by using commands like iostat, but there was no visibility, and no way to spread the load. Oracle VM Server for SPARC addresses this by adding command output that shows which path is active, and let you switch the active path to one of the available paths. Now, the command 'ldm list-bindings' shows which path is active, and the command 'ldm set-vdisk' lets you set which path is active. For further details and syntax, please see the documentation at Configuring Virtual Disk Multipathing

This paper shows how to configure to meet demanding performance and availability requirements. Topics include:
- Oracle VM Server for SPARC definitions, concepts and deployment options.
- Software, hardware, and firmware requirements.
- Best Practices for optimal performance.
- Best Practices for resiliency and availability.
The paper includes specific recommendations, describes the reasons behind them, and illustrates them with examples taken from actual systems.
