Embodiments are directed to creating global, aggregated namespaces for storage management and to providing consistent namespaces in a distributed storage system. In one scenario, a computer system defines data storage objects for each data storage node. The data storage objects uniquely identify storage elements of the data storage nodes, where each data storage object includes various associated attributes. The computer system replicates the defined data storage objects and any associated attributes from a first data storage node to a second, different data storage node among the data storage nodes. As such, the defined data storage objects are visible from any node in the data storage nodes. The computer system also aggregates the defined data storage objects for each of the data storage nodes and creates a global, aggregated namespace that includes the aggregated data storage objects for each of the data storage nodes.

Creating global aggregated namespaces for storage management

The provisioning of a volume that has multiple tiers corresponding to different trait sets. The volume to be provisioned is identified along with multiple tiers that are to be in the volume. For each of the tiers that are to be provisioned within the volume, a corresponding trait set is identified as to be applied to each tier. This corresponding trait set may be based on underlying storage systems that are available at the time of provisioning, or which are anticipated to be available. The volume is then caused to be provisioned with the corresponding tiers having the corresponding trait sets. Also, the provisioning of a file, which is determined to have one or more storage traits. Based on these storage traits, the file is then caused to be assigned to an appropriate tier.
