Administering SmartIO
The SmartIO feature of Storage Foundation and High Availability Solutions (SFHA Solutions) enables data efficiency on your solid-state drives (SSD) through I/O caching.
SmartIO uses a cache area on target devices. The cache area is the storage space that SmartIO uses to store the cached data and the metadata about the cached data. The type of the cache area determines whether it supports VxFS caching or VxVM caching. To start using SmartIO, you can create a cache area with a single command, while the application is online. When the application issues an I/O request, SmartIO checks to see if the I/O can be serviced from the cache. As applications access data from the underlying volumes or file systems, certain data is moved to the cache based on the internal heuristics. Subsequent I/Os are processed from the cache.
SmartIO supports read caching for the VxFS file systems that are mounted on VxVM volumes, in several caching modes and configurations. SmartIO also supports block-level read caching for applications running on VxVM volumes.
Note:
SmartIO writeback caching is currently not supported in SF Oracle RAC environments.
For more information on using and administering SmartIO, see the Veritas InfoScale SmartIO for Solid State Drives Solutions Guide.
