About SmartIO in the Solaris virtualized environments

Storage Foundation and High Availability Solutions are supported in the Solaris virtualized environments. This section describes how you can use SmartIO in the Solaris virtualized environments.

Table: Solaris: Oracle VM Server for SPARC shows how SmartIO can be used in the Oracle VM Server for SPARC environment.

When you install Storage Foundation and High Availability Solutions in the guest, you can use SmartIO to cache data onto an SSD or any other supported fast device. The SSD used for the cache can be either a PCIe or SAS device, or an array-based SSD.

When you install Storage Foundation and High Availability Solutions in the control domain, you can use VxVM read caching at the control domain level.

Storage Foundation for Oracle RAC is supported only on guest domains.

If an array-based SSD is used, live migration is supported with SmartIO caching. With direct attached devices (PCIe), live migration is not supported if SmartIO caching is enabled. If you need to perform live migration, you can use manual steps.

See Performing live migration between LDOMs in the SmartIO environment.
