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.
Table: Linux: SmartIO support in KVM
Configuration in guest: | Configuration in host: | Caching takes place: | VxVM read caching | VxFS read caching | VxFS writeback caching |
|---|---|---|---|---|---|
SF | any (SF or SFCFSHA) | in the guest | Yes | Yes | Yes |
SFHA | any (SF or SFCFSHA) | in the guest | Yes | Yes | Yes |
SFCFSHA | any (SF or SFCFSHA) | in the guest | Yes | Yes | Yes |
Any | SF | in the host | Yes | Yes | Yes |
Any | SFCFSHA | in the host | Yes | Yes | Yes |
Table: Linux: SmartIO support in VMware shows how SmartIO can be used in the VMware environment.
