Abstract

A system facilitates access to data in a network and includes a cache that stores instructions. A processor executes the instructions including: caching processing configured to integrate caching into a local cluster file system, and cache local file data in the cache based on fetching file data on demand from a remote cluster file system. The cache is visible to file system clients as a Portable Operating System Interface (POSIX) compliant file system. Applications execute on a multi-node cache cluster using POSIX semantics via a POSIX compliant file system interface. Data cache is locally and remotely consistent for updates.
