Abstract
According to one embodiment, provided is a storage management system having a processor and managing a plurality of storages, in which the storage has a plurality of types of components, and performs redundantization of a data to be stored by combining the plurality of components, the storage management system has component management information indicating redundancy set for the component itself, and the processor sets a method of data protection of the storage based on the component management information and a request for the data protection for the data stored in the storage.
Claims10
A storage management system having a processor and managing a plurality of storages,
- wherein the at least one storage included in the plurality of storages has a plurality of types of components, performs redundantization of a data to be stored by combining the plurality of components, wherein performing redundantization of data comprises
- receiving write data from a storage service processing program,
- transmitting write data to at least one data protection destination by referring to a volume management table, and
- writing a completion report, received from the at least one data protection destination, requiring synchronous writing, and
- wherein the storage management system comprises a back-end device management table and has component management information indicating redundancy set for the component itself, and
- wherein the processor sets a method of data protection of the storage based on the component management information and a request for the data protection for the data stored in the storage, wherein the method of data protection comprises
- performing redundantization destination selection process from a viewpoint of each component, and
- performing a redundantization destination process from a viewpoint of the entire system.
A management method executed by a storage management system having a processor and managing a plurality of storages,
- wherein the at least one storage included in the plurality of storages has a plurality of types of components, and a data to be stored is redundantized by combining the plurality of components, wherein performing redundantization of data comprises
- receiving write data from a storage service processing program,
- transmitting write data to at least one data protection destination by referring to a volume management table, and
- writing a completion report, received from the at least one data protection destination, requiring synchronous writing, and
- wherein the storage management system comprises a back-end device management table and has component management information indicating redundancy set for the component itself, and
- wherein the processor sets a method of data protection of the storage based on the component management information and a request for the data protection for the data stored in the storage, wherein the method of data protection comprises
- performing redundantization destination selection process from a viewpoint of each component, and
- performing a redundantization destination process from a viewpoint of the entire system.
