摘要： In a storage apparatus system including a plurality of remote copy ports for executing remote copy processing, loads due to the remote copy processing are dispersed among the plurality of remote copy ports. To this end, information indicative of load states of the plurality of remote copy ports in the storage apparatus system is stored in a common memory of the storage apparatus system and the storage apparatus system causes a remote copy port having a lighter load to execute the remote copy processing with reference to the information. Further, even with regard to the remote copy processing being executed, the storage apparatus system changes the remote copy port for executing the remote copy processing in accordance with the load states of the remote copy ports.

摘要： An inter-OS control software for switching OS's in operation executed on a single CPU is installed, and plural OS's are made alternately executed. A control program is executed exclusively on one OS, which controls the controlled apparatus. A supervisory control program and a development environment program are executed on another OS, and a memory space is divided so as to make no effect for the operation of the control program. A higher real-time performance and reliability can be established with a single CPU architecture.
摘要翻译： 安装用于在单个CPU上执行的用于切换操作系统的操作系统间控制软件，并且交替地执行多个操作系统。 控制程序仅在一个操作系统上执行，该控制程序控制受控设备。 在另一个OS上执行监视控制程序和开发环境程序，并且对存储器空间进行分割，从而对控制程序的操作没有影响。 可以使用单个CPU架构来建立更高的实时性能和可靠性。
