Data storage tier definitions and associated tier attributes are received and associated with the digital tag. Resulting specified tiers of the hardware storage system a defined for storage of specified portions of the data and each portion of data is stored within an associated tier.

Abstract: Approaches presented herein enable generation of a multi-dimensional tag metric in a cloud resource management environment. More specifically, a tagging namespace is provided for managing a resource in the cloud resource management environment. This namespace comprises at least two dimensions and a plurality of positions. A set of tags associated with the resource are received into the tagging namespace. A match of each tag of the set of tags to a position within the namespace into which that tag was received is verified and an alert is triggered in the case verification fails. Alternatively, in the case verification is successful, the tag-containing namespace is validated as a multi-dimensional tag metric.
