    摘要: A method of selecting logical volumes that are the targets for data migration to equilibrate the load on a system, based on the accessing data of the physical drives and logical drives under the disk array controllers, without increasing the load of the disk array controller. An external manager communicates with two or more disk array controllers, gathers and manages the access data and the configuration data relating to the physical drives and logical volumes of each disk array controller, and prepares an optimum data migration instruction to equilibrate the access load.

    摘要: A disk subsystem assures the sequence and the coherence of data updating with two or more disk subsystems is provided with an asynchronous remote copy function. A main center 9 includes a computer system having the configuration of slave subsystems 3-2 to 3-n connected with a master disk subsystem 3-1. It secures the coherence between data at the main center 9 and the remote center 10 at the temporary suspension by repeating temporary suspension and release of the temporary suspension of the remote copy by the master subsystem 3-1 at predetermined opportunities. It also repeats temporary suspension and release of the temporary suspension of the remote copy by slave subsystems 3-2 to 3-n connected to it.
