About SmartIO in the Linux virtualized environment

In the Linux virtualized 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.

In the KVM and RHEV environments, SmartIO caching does not support live migration of the guest.

For VMware, SmartIO does support vMotion if DMP for VMware (SmartPool) is enabled in the ESXi hypervisor.

Storage Foundation for Oracle RAC is not supported in the Linux virtualized environment.

The following tables show how SmartIO can be used in the Linux virtualized environments.
