Abstract:
In a network comprising first and second nodes coupled to each other via a first communication link, and a peripheral data storage device coupled to the first and second nodes via a second communication link, a method comprising:generating a request to access data of a file stored in the peripheral data storage device; a file system, executing on the first node, generating a first message in response to generation of the request; a first software module, executing on the first node, generating an instruction in response to the file system generating the first message; transmitting the instruction to the second node via the first communication link; invalidating a portion of meta data stored in memory associated with the second node in response to the second node receiving the instruction, wherein the portion of meta data stored in memory associated with the second node corresponds to the file; the first node accessing data of the file via the second communication link in response to invalidation of the portion of meta data stored in memory associated with the second node; the file system modifying meta data stored in memory associated with the first node in response to accessing data in the file, wherein the meta data stored in memory associated with the first node corresponds to the file.
