STORAGE SITE SELECTION IN A MULTI-TARGET ENVIRONMENT USING WEIGHTS

摘要

A method, computer program product, and/or system for performing a selection of a plurality of auxiliary storage sites in a multi-target environment in preparation for a hyper exchange are/is provided. To perform the selection, a failure is first detected with respect to a primary storage site in the multi-target environment. Then, aggregate weights are determined based on a management policy for the plurality of auxiliary storage sites. In turn, an auxiliary storage site with a first aggregate weight is selected from the plurality of auxiliary storage sites. With the auxiliary storage site selected, the hyper exchange of a plurality of systems in a multi-target environment in response to the failure is triggered from the primary storage site to the auxiliary storage site with the first aggregate weight.

1. A method for performing a selection of a plurality of auxiliary storage sites in a multi-target environment in preparation for a hyper exchange, comprising:
detecting, by a computing facility comprising a processor and a memory, a failure with respect to a primary storage site in the multi-target environment; determining, by the computing facility, aggregate weights based on a management policy for each of the plurality of auxiliary storage sites; selecting, by the computing facility, an auxiliary storage site with a first aggregate weight from the plurality of auxiliary storage sites; and triggering, by the computing facility, the hyper exchange of a plurality of systems in a multi-target environment in response to the failure from the primary storage site to the auxiliary storage site with the first aggregate weight.
