A method of, and apparatus for, predicting the performance of a data storage resource forming part of a networked electronic data store is described. The method includes representing the data storage resource as a plurality of separate virtual storage components, each virtual storage component representing a part of the data storage resource and having at least one operational state selectable from a pool of operational states. The method further includes obtaining resource profile data from the data storage resource, and modeling the performance of the data storage resource by assigning, from the pool, an operational state to each virtual storage component to fit the resource profile data. Thus, the data storage resource can be represented as a collection of virtual storage components, each having a dynamically-assignable operational state. This enables the modeling of the performance of the data storage resource to be simplified significantly.
