Abstract
Selecting a storage device to be mapped to a requested virtual disk includes maintaining attributes for a set of storage devices including a cost attribute, a capacity attribute and quality-of-service attributes. A request for a virtual disk includes request parameters including a price parameter, a capacity parameter and quality-of-service parameters. A device selection function generates a score for each storage device based on the request parameters and the storage device attributes, and identifies a best suited storage device by comparing the respective scores of the storage devices. The virtual disk is then created in satisfaction of the request with a mapping to the identified storage device to provide underlying physical data storage for the virtual disk.
