Cache Device Usage

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.

BUI value	CLI value	Description
All data and metadata	all	All normal file or LUN data is cached, as well as any metadata.
Metadata only	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	none	No data in this share is cached on the cache device. Data is only cached in the primary cache or stored on data devices.
