Patent abstract
A technique for storing metadata changes includes caching metadata changes in a persistent metadata cache. The persistent metadata cache is configured to cache metadata reads and writes directed to a set of internal volumes of the data storage system. A file system can access pages of the persistent metadata cache by specifying an identifier of an internal volume and an offset into that volume to which the metadata changes are directed.
