Abstract
A method, computer program product, and computing system for freeing up cache space includes identifying a portion of cache space for removal from a cache system, thus defining a cache portion to be removed, and ceasing to promote the cache portion to be removed. Data that needs to be relocated within the cache portion to be removed is identified, thus identifying flushable data. The flushable data is relocated to a backend storage system associated with the cache portion to be removed.
