Abstract
A storage system comprises a storage array, a network file system configured to communicate with the storage array, a server associated with the network file system, a client configured to communicate over a first path with the network file system via the server and to communicate directly with the storage array over a second path that bypasses the network file system, and a block cache arranged in the second path between the client and the storage array. The server may comprise a multi-path file system (MPFS) server and the client may comprise an MPFS client, with the MPFS server and the MPFS client being configured to communicate using a file mapping protocol. The block cache is illustratively implemented using a VFCache or other type of server flash cache.
