  • Storage controller software development support system and software development support method
    Patent number: 7353496
    Abstract: In the present invention, the scope and degree of the effect of hardware alterations on software is grasped, and development is performed while making coordination between software and hardware. The storage system comprises a plurality of hardware elements and a plurality of software elements, and these respective elements are connected via a plurality of interface elements. The development support system respectively acquires and analyzes specification information relating to the hardware elements and software elements comprising the storage system, and produces software effect information that indicates the effect on the software. The development sections promote cooperative development while referring to the software effect information.
