Abstract
To enable appropriate data migration scheduling between storage apparatuses. A system stores load information indicating a temporal change in a load of each of a plurality of storage apparatuses. The system selects a data migration source from the plurality of storage apparatuses based on the load information. The system estimates a data migration time length of a target volume selected from the data migration source based on a previously designated feature, which is related to the target volume or a combination of the data migration source and a data migration destination. The system generates a schedule indicating a data migration time period of the target volume based on the migration time length and the load information.
Claims10
A storage management system for managing a plurality of storage apparatuses, comprising:
- one or more processors;
- and
- one or more memory devices, wherein
- the one or more memory devices store load information indicating a temporal change in a load of each of the plurality of storage apparatuses, and
- the one or more processors select a data migration source from the plurality of storage apparatuses based on the load information, estimate a data migration time length of a target volume selected from the data migration source based on a previously designated feature, which is related to the target volume or a combination of the data migration source and a data migration destination, and generate a schedule indicating a data migration time period of the target volume based on the migration time length and the load information.
A method for managing a plurality of storage apparatuses, executed by a system storing load information indicating a temporal change in a load of each of the plurality of storage apparatuses, the method comprising:
- selecting a data migration source from the plurality of storage apparatuses based on the load information;
- estimating a data migration time length of a target volume selected from the data migration source based on a previously designated feature, which is related to the target volume or a combination of the data migration source and a data migration destination;
- and
- generating a schedule indicating a data migration time period of the target volume based on the migration time length and the load information.
