A method is used in managing provisioning of storage resources. An access is provided to a provisioning decision making service configured to derive a storage provisioning decision based on information provided to the provisioning decision making service. Provisioning of storage resources is enabled on a storage system over a communication medium by using the provisioning decision making service.

Managing provisioning of storage resources

Described are techniques for selecting resources for provisioning. A usage definition, including an objective function, and first set of logical profiles based on core criteria are selected. Each of the logical profiles in the first set represents a resource set characterized by a core criteria value set that specifies values for the core criteria. A second set of resulting objective function values are determined by evaluating the objective function for each of the logical profiles in the first set. A highest ranked one of the resulting objective function values in the second set is selected having a corresponding first logical profile of the first set and a corresponding core criteria value set. A third set of resources is selected which is characterized by the corresponding core criteria value set for the first logical profile. The third set of resources is any of recommended or selected for provisioning.

Resource provisioning based on logical profiles and objective functions

Described are techniques for selecting resources for provisioning. A usage definition, including a piecewise objective function, and first set of logical profiles based on core criteria are selected. Each of the logical profiles in the first set represents a resource set characterized by a core criteria value set that specifies values for the core criteria. A second set of resulting objective function values are determined by evaluating one piece of the objective function for each of the logical profiles in the first set. A highest ranked one of the resulting objective function values in the second set is selected having a corresponding first logical profile of the first set and a corresponding core criteria value set. A third set of resources is selected which is characterized by the corresponding core criteria value set for the first logical profile. The third set of resources is any of recommended or selected for provisioning.

Resource provisioning based on logical profiles and piecewise objective functions

An improved technique uses an expert system to provide automated provisioning of resources for a storage system. Along these lines, a user submits values of a set of provisioning targets parameters in a administrative interface screen to a storage processing device. The expert system uses these values to form a set of facts within an expert system stored on the storage processing device that includes a knowledge base having a set of logical rules and an inference engine. The storage processing device then inputs these facts and logical rules into the inference engine which is configured to fire logical rules having preconditions that match the facts. The actions of these logical rules then provide content for the provisioning of the storage resources, which are displayed to the user or used for automatic storage provisioning operations.
