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.
摘要翻译：当存储装置接收到对LU0中的存储区域的写入请求时，所有者访问处理单元参照锁定信息表来判断对存储区域的写入处理是否被限制。当限制时，所有者访问处理单元不对存储区域执行写入处理，并且如果不受限制，则所有者访问处理单元在锁定信息表的存储区域的列中设置写入处理限制对存储区域进行写入处理。如果其他存储装置接收到相同区域的写入请求，则所有者访问处理单元发送锁定预约请求以限制LU的区域的写入处理，并且如果它们接收到来自该存储装置的锁定预约请求的接受，则所有者访问处理单元对存储区域执行写入处理。

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.
摘要翻译：当提供给要传送的帧的输出端口的缓冲存储器的容量可用性超过预定值时，交叉开关用于帧的路径改变。当输出端口的缓冲存储器的容量可用性为预定值或更低时，将帧写入共享存储器。然后，从共享存储器中读取帧以传输到输出端口。通过使用交叉开关选择性地执行帧传送和经由共享存储器的帧传送，即使端口缓冲器溢出，也可以降低效果，并且可以有利地提高写入吞吐量。

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.
摘要翻译：每个具有双端口的磁盘适配器和磁盘驱动器通过交换机连接在双回路中。根据磁盘适配器向其中一个磁盘驱动器发出的命令的类型（读/写）确定要传送命令的目标循环。磁盘适配器发出读取和写入命令，以便并行执行读取交换和写入交换。
