  • Method and system for maintaining data coherency in a dual input/output adapter utilizing clustered adapters
    Patent number: 6530003
    Abstract: A method for maintaining data coherency in a dual Input/Output(I/O) adapter having primary and secondary adapters, wherein each of the primary and secondary adapters includes resident write cache data and directory storage devices. The method includes utilizing a split point to separate each of the cache data and directory storage devices into first and second regions, wherein the first regions contain the primary adapter cache data and directory information and the second regions contain the secondary adapter cache data and directory information. Information stored in the primary adapter cache data and directory storage devices is mirrored into the secondary adapter cache data and directory storage devices or, alternatively, information stored in the secondary adapter cache data and directory storage devices is mirrored into the primary adapter cache data and directory storage devices utilizing a dedicated communication link, such as a high-speed serial bus, between the primary and secondary adapters.
