  • Method and system allowing direct data access to a shared data storage subsystem by heterogeneous computing systems
    Patent number: 5926833
    Abstract: A method and system are provided which allow heterogeneous computing systems to have direct access to the same data storage areas on a shared data storage subsystem such that the method and system are transparent to the heterogeneous computing systems. The method and system achieve the foregoing via the following steps. A data storage subsystem controller queries all computing systems having direct access to the same data storage areas of a shared data storage subsystem as to the operating systems utilized by such computing systems. In response to answers received in response to the queries, the data storage subsystem controller creates and stores meta-data which associates each computing system having direct access with whatever operating system is running on each computing system having direct access.
