About SmartIO in the Linux virtualized environment
In the Linux virtualized environment, when you install InfoScale solutions in the guest, you can use SmartIO to cache data onto an SSD or any other supported fast device.
SmartIO caching does not support live migration of the guest in KVM environments.
For VMware, SmartIO does support vMotion if DMP for VMware (SmartPool) is enabled in the ESXi hypervisor.
See About the SmartPool feature.
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.
Table: Linux: SmartIO support in KVM shows how SmartIO can be used in the KVM environment.
