Controls whether cache devices are used for the share. By default, all datasets make use of
any cache devices on the system. Cache devices are configured as part of the storage pool and
provide an extra layer of caching for faster tiered access. For more information on cache devices,
see the Chapter 5, Storage Configuration section. This property is independent
of whether there are any cache devices currently configured in the storage pool. For example, it is
possible to have this property set to "all" even if there are no cache devices present. If any such
devices are added in the future, the share will automatically take advantage of the additional
performance. This property does not affect use of the primary (DRAM) cache.
All data and metadata
All normal file or LUN data is cached, as well as any metadata.
Only metadata is kept on cache devices. This allows for rapid traversal of directory
structures, but retrieving file contents may require reading from the data devices.
Do not use cache devices
No data in this share is cached on the cache device. Data is only cached in the primary cache
or stored on data devices.
