摘要： A consumption value of each storage medium and an upper limit related to writing are managed. Respective consumption value and the upper limit of each of two or more storage media out of a plurality of storage media constituting a storage media group are specified, and a remaining use period value is computed for each of the storage media using the upper limit and the consumption value. Based on each of the computed remaining use period values, data in at least one storage medium out of a plurality of storage media belonging to the selected storage area group is shifted to a storage medium which is different form the storage area group.

摘要： Exemplary embodiments provide a technique to reduce the traffic between storage devices during data migration. In one embodiment, a system comprises a plurality of storage systems which are operable to migrate a set of primary and secondary volumes between the storage systems by managing and copying, between the storage systems, a plurality of same data and a plurality of difference data between the primary and secondary volumes and location information of each of the plurality of difference data, the location information identifying a location of the difference data in the primary or secondary volume associated with the difference data. Each secondary volume which corresponds to a primary volume, if said each source secondary volume contains data, has a same data as the primary volume and, if said each secondary volume is not synchronized with the primary volume, further has a difference data with respect to the primary volume.

摘要： A method for controlling data for a storage system comprises: receiving a write input/output (I/O) command of a data from a host computer, the write I/O command including an application ID identifying an application operating on the host computer which sends the write I/O request; maintaining a record of a relation between the application ID in the write I/O command and a storage location of the data to be written in a first volume of the storage system; determining, based on the application ID, whether a data transfer function between the first volume and a second storage volume is to be performed on the data beyond writing the data to the storage location in the first volume; and if the data transfer function is to be performed on the data, then performing the data transfer function on the data to the second volume.

摘要： Systems and methods directed to preventing a single point of failure by utilizing N_Port ID Virtualization (NPIV). During some procedures used by storage subsystems, such as migration, there is oftentimes only a single path from a host to a storage subsystem, which causes a potential single point of failure for the entire system. By utilizing NPIV, this problem may be mitigated.

A first data storing region of one of the first storage volumes is allocated from a first pool by the first storage controller. A second data storing region of another one of the first storage volumes is allocated from a second pool by the first storage controller. A third data storing region of one of the second storage volumes is allocated from the first pool by the second storage controller. A fourth data storing region of another one of the second storage volumes is allocated from the second pool by the second storage controller.

摘要： A system comprising a plurality of storage systems, which uses storage devices of multiple levels of reliability. The reliability as a whole system is increased by keeping the error code for the relatively low reliability storage disks in the relatively high reliability storage system. The error code is calculated using hash functions and the value is used to compare with the hash value of the data read from the relatively low reliability storage disks.
