Abstract
A disk array includes a system and method for cache management and conflict detection. Incoming host commands are processed by a storage controller, which identifies a set of at least one cache segment descriptor (CSD) associated with the requested address range. Command conflict detection can be quickly performed by examining the state information of each CSD associated with the command. The use of CSDs therefore permits the present invention to rapidly and efficiently perform read and write commands and detect conflicts.
