摘要： A storage system (10) comprises a first disk controller (104) coupled to a host computer (101) and at least one first disk (105) coupled to said first disk controller (104). The storage system (10) is coupled to another storage system (20), which comprises a second disk controller (113) and at least one second disk (114). The first disk controller (104) receives a write request issued from said host computer (101), selects a storage system including a target disk corresponding to first disk identification information included in said write request, obtains, if the selected storage system is said another storage system (20), identification information designating said another storage system (20) and second disk identification information designating one of said at least one second disk based on said first disk identification information, and sends a write request to said another storage system (20) according to said identification information designating said another storage system (20) and said second disk identification information.

摘要： A heterogeneous computer system, a heterogeneous input/output system and a data back-up method for the systems. An I/O subsystem A (113, 114) for open system and an I/O subsystem B (104, 105) for a mainframe are connected by a communication unit. In order to back up the data from at least a disk connected to the I/O subsystem B in a MT library system and in order to permit the mainframe to access the data in the I/O subsystem B, the I/O subsystem A includes a table (314, 315) for assigning a vacant memory address in a local subsystem to the memory of the I/O subsystem for an open system. A request of variable-length record format received from the mainframe is converted into a fixed-length record format for the subsystem B. The disk designated according to the table is accessed, and the data thus obtained is sent to the mainframe and backed up in the back-up system.

摘要： A heterogeneous computer system, a heterogeneous input/output system and a data back-up method for the systems. An I/O subsystem A (113, 114) for open system and an I/O subsystem B (104, 105) for a mainframe are connected by a communication unit. In order to back up the data from at least a disk connected to the I/O subsystem B in a MT library system and in order to permit the mainframe to access the data in the I/O subsystem B, the I/O subsystem A includes a table (314, 315) for assigning a vacant memory address in a local subsystem to the memory of the I/O subsystem for an open system. A request of variable-length record format received from the mainframe is converted into a fixed-length record format for the subsystem B. The disk designated according to the table is accessed, and the data thus obtained is sent to the mainframe and backed up in the back-up system.
