Oracle VM Server for SPARC Support

I saw a couple of related questions about Oracle VM Server for SPARC 3.3 support recently:

Are T7 servers with Oracle VM Server for SPARC 3.3 supported in Ops Center?

Yep. You can take a look at the Certified Systems Matrix to see the full list of supported systems.

What if I want to downgrade systems to Oracle VM Server for SPARC 3.2?

That's not something we've tested or certified.

Are live migration and automatic recovery supported for OVMSS 3.3?

Yes, the full feature set for OVMSS is supported for version 3.3. One issue worth mentioning, though, is that the option for setting the maximum bandwidth for a guest doesn't work properly in 3.3; we're working on that issue.

OVM Server for SPARC Enhancements

Oracle VM Servers for SPARC saw a few improvements in Ops Center 12.2. In addition to brownfield support, we've made a number of enhancements to let you add OVM Servers for SPARC to a Server Pool and enable migration of their guests.

-When you discover an OVMSS Control Domain and manage it with an Ops Center Agent, its guests are automatically discovered as well. The guest metadata is initially put in the local metadata library in the /guests directory, but you can move it from one library to another to enable migration.

-Once you've discovered an OVMSS control domain, you can add it to a server pool, even if it's already configured and running logical domains. Even if live migration between OVMSS systems isn't possible due to CPU incompatibilities, you can still put them in a server pool together and enable guest recovery by configuring the CPU architecture of the guest domain as generic.

-You can mark a guest's storage as shared to indicate that it's available to other managed OVM Server systems with the same back-end name. This lets you use storage not fully managed in an Ops Center library as part of guest migration.

Put together, these enhancements make it much easier to manage and maintain OVMSS guests.
