INTEGRATED CIRCUIT DEVICE, DATA STORAGE ARRAY SYSTEM AND METHOD THEREFOR

摘要

An integrated circuit device (200) comprises a data storage array controller (210) for providing data storage array functionality for at least one data storage array (220). The data storage array controller (210) comprises an address window controller (340) arranged to receive at least one data storage device access command, and upon receipt of the at least one data storage device access command the address window controller (340) is arranged to compare a target address of the at least one data storage device access command to an address window for a target storage device (222, 224, 226) of the at least one data storage device access command, and if the target address is outside of the address window for the target storage device (222, 224, 226), block the at least one data storage device access command.
