Resource provisioning based on logical profiles and piecewise objective functions

摘要

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.

1. A method for use in selecting resources for provisioning, the method comprising:
selecting a usage definition and a first set of one or more logical profiles based on one or more core criteria, wherein said usage definition includes a piecewise objective function with each piece of the piecewise objective function characterizing distinct storage usage requirements, and wherein each of the logical profiles in the first set represents a resource set of one or more physical storage resources characterized by a core criteria value set that specifies one or more values for the one or more core criteria; determining a second and a third set of resulting objective function values by evaluating each respective piece of the objective function for each of the logical profiles in the first set, wherein each logical profile in the first set has a different corresponding resulting objective function value in the second and the third sets; selecting highest ranked objective function values in the second and the third sets, wherein the highest ranked objective function values in the second and the third sets have corresponding logical profiles in the first set and corresponding core criteria value sets; and determining a fourth set of physical storage resources characterized by the corresponding core criteria value sets for logical profiles, wherein the fourth set is any of recommended or selected for provisioning storage from the physical storage resources.
