Patent

CA 2066443

A file server architecture is disclosed, comprising as separate processors, a network controller unit (110), a file controller unit (112) and a storage processor unit (114). These units incorporate their own processors, and operate in parallel with a local Unix host processor (118). All networks are connected to the network controller unit (110), which performs all protocol process- ing up through the NFS layer. The virtual file system is implemented in the file controller unit (112) and the storage processor (114) provides high-speed multiplexed access to an array of mass storage devices. The file controller unit (112) controls file infor- mation caching through its own local cache buffer, and controls disk data caching through a large system memory which is acces- sible on a bus by any of the processors.
