A FlexCache volume is a sparsely populated volume on a local (caching) storage system that is backed by a volume on a different, possibly remote, (origin) storage system. A sparsely populated volume, sometimes called a sparse volume, provides access to all data in the origin volume without requiring that the data be physically in the sparse volume.
You use FlexCache volumes to speed up access to remote data, or to offload traffic from heavily accessed volumes. Because the cached data must be ejected when the data is changed, FlexCache volumes work best for data that does not change often.
