Zusammenfassung:A method of managing a storage system having one or more storage devices includes receiving a request to access, in a tiered data structure, a data object and one or more attributes of the data object and processing the access request. The request includes a first key value for the data object and respective second key values for the one or more attributes of the data object. Modified key values for the attributes of the data object are generated in accordance with at least a portion of the first key value and used to access tree entries for the data object attributes in one or more leaf nodes of the tiered data structure. A tree entry for the data object is also accessed from the same set of one or more leaf nodes.
