Correlating storage system event alerts by receiving notice of an event, determining a first storage network system (SNS) resource related to the event, determining instantiated dependencies between the first SNS resource and a second SNS resource, correlating the event with a second event according to the instantiated dependencies, and providing notice of the correlated events.

Configuration-based alert correlation in storage networks

Embodiments of the present invention disclose a method, computer program product, and system for snapshot management in a storage infrastructure. A computer accesses a first snapshot captured in a first layer of the storage infrastructure. The computer accesses a second snapshot captured in a second layer of the storage infrastructure. The computer produces a determination that the first snapshot in the first layer of the storage infrastructure is one or more of: inconsistent with the second snapshot in the second layer of the storage infrastructure and a duplicate of the second snapshot in the second layer of the storage infrastructure. The computer removes the first snapshot in the first layer of storage infrastructure responsive to the determination.

Snapshot management in hierarchical storage infrastructure

A mechanism is provided for providing storage resources of a storage management system. A storage service request is received comprising an indication of a service class. A determination is made of all resource managers mapped to the indicated service class according to a first mapping. For each of the determined resource managers: a determination is made of selected ones of all the storage resources controllable by the determined resource manager; monitoring data of the selected storage resources is gathered; the gathered monitoring data is compared for calculating a score for each one of the selected storage resources; and at least one function of the determined resource manager operable to control the storage resource having an optimum score is called.

Providing storage resources upon receipt of a storage service request

Embodiments of the present invention disclose a method, computer program product, and system for snapshot management in a storage infrastructure. A computer identifies one or more snapshots within layers of the storage infrastructure. The computer determines one or more relationships of the one or more identified snapshots of the storage infrastructure. The determined relationships include, at least in part, relations of one or more entities included in the one or more snapshots to additional one or more entities in the one or more snapshots of the storage infrastructure. The computer identifies the one or more duplicate snapshots by utilizing the one or more determined relationships of the one or more identified snapshots. The computer consolidates the one or more identified duplicate snapshots in the storage infrastructure. In another embodiment, the computer identifies one or more inconsistent snapshots, and consolidates the one or more inconsistent snapshots in the storage infrastructure.

Various embodiments storing volumes of data in a data storage system, including one or more data storage containers, the data storage containers being thin-provisioned to provide virtual data storage capacity which is greater than a real data storage capacity of the data storage hardware are provided. In one embodiment, by way of example only, a real data storage capacity of the data storage system for accommodating new volumes is determined. Over-allocation information relating to one or more data storage containers is determined. Extrapolated future anticipated use of one or more containers of the data storage system from historical data storage use information is determined. One or more candidate data storage containers on the basis of information from the determining the real data storage capacity, over-allocation information, and the extrapolated future anticipated use is selected. Additional system and computer program product embodiments are disclosed and provide related advantages.
