摘要： When a storage apparatus receives a write request for a storage area in LU0, an owner access processing unit judges whether write processing for the storage area is restricted with reference to a lock information table. When it is restricted, the owner access processing unit does not perform write processing for the storage area, and, if it is not restricted, the owner access processing unit sets a write processing restriction in a column of the storage area of the lock information table and performs write processing for the storage area. If other storage apparatuses receive the write request for the same area, the owner access processing unit transmits the lock reservation request to restrict write processing for the area of the LU, and if they receive acceptance of the lock reservation request from this storage apparatus, the owner access processing unit performs write processing for the storage area.

摘要： When the capacity availability of buffer memory provided to an output port of a frame to be transferred is exceeding a predetermined value, a crossbar switch is used for path change of the frame. When the capacity availability of the buffer memory of the output port is the predetermined value or lower, the frame is written into shared memory. Then, the frame is read from the shared memory for transfer to the output port. By selectively performing frame transfer using the crossbar switch and frame transfer via the shared memory, the effects can be reduced even if the port buffer overflows, and the writing throughput can be favorably improved.

摘要： A disk adapter and disk drives, each having dual ports, are connected in dual loops via a switch. A destination loop to which a command is to be transferred is determined, according to the type (Read/Write) of the command that the disk adapter issues to one of the disk drives. The disk adapter issues Read and Write commands so that the Read exchange and the Write exchange are executed in parallel.
