    摘要: After a host creates a memory area in an external storage device, a setting is made such that the host can manage the memory area in the external storage device, so as to prevent an access to the storage device by another host to protect data therein. A second storage device creates a memory area therein, an iSNS server registers a lower DD between first and second storage devices, the first storage device makes a mapping-setting registration for names of a memory area for use and an external memory area, and the iSNS server registers an upper DD between the host and the first storage device, and the host mounts a memory area of the first storage device.

    摘要: In a storage system having a function of acquiring update history information in correspondence with a write operation from a host, update data according to the amount of data written will become enormous. Thus, there is a problem in that long-term backup and data management using update history information is not possible. A management computer defines a service level according to time progress of data, and stores and manages update history information according to the service level in the respective stages. The management computer manages the update history information, and partially migrates update data from a certain storage system to another storage system according to the service level required in the data. The management computer also restores data in the storage system to which the update data was migrated.

    摘要: A computer system having a work computer, first storage systems, and second storage systems also has a network, a network routing device, and a management computer. Upon receipt of the update data from the work computer, the first storage system stores the update data in a first storage volume and stores the update data in a second storage volume until the update data is transferred to the second storage system. The management computer obtains an used capacity of the second storage volume of each of the first storage systems and controls the routing of the data by the network routing device based on the obtained used capacity to prevent the cache of each of the storage systems from being overflown.

    摘要: In remote data replication between storage systems, there are cases where the storage extent capacity used as the temporary storage extent in the storage system will incur waste. In a system having a management computer, a host computer, a first storage system, and a second storage system, when maintaining the replicated data of the first storage system in the second storage system via remote data replication, a change or the like in the traffic from the host computer to the first storage system is monitored, and the management computer instructs the storage system to switch the remote data replication mode in accordance with such traffic.
