Abstract

A method, computer program product, and computing system for defining a first server and a second server within a server cluster. The first server includes a first cache system and the first and second servers are coupled to a data array that includes a LUN. The LUN is reserved for exclusive access by the first server, thus generating a first server reservation. Data associated with the LUN is cached within the first cache system of the first server. A loss of the first server reservation is sensed. In response to a loss of the first server reservation, the first cache system of the first server is purged.
