Capacity accounting for heterogeneous storage systems

A method comprising:

• determining a storage content relationship between a primary storage object and a replicated storage object of the heterogeneous storage objects, wherein the primary storage object and the replicated storage object are updated based on a same storage content;
• generating, in a data processing system, a relationship data structure of storage consumer accounts and heterogeneous storage objects based on the storage content relationship;
• determining, in the data processing system, a storage tier label for each of the heterogeneous storage objects based on a storage object service type and a storage object technology type, the storage tier label associated with a storage cost;
• and
• generating, in the data processing system, a storage cost accounting of a storage consumer by traversing the relationship data structure based on the storage tier label.

A processing system comprising:

• a processor;
• a computer-readable storage medium storing modules executable by the processor, the modules including:
• a database module configured to, when executed by the processor:
• ascertain a set of heterogeneous storage objects provisioned for a storage consumer, the heterogeneous storage objects categorized by storage object hierarchy levels;
• identify an association between the storage consumer and a storage object hierarchy level;
• and
• a capacity accounting module configured to, when executed by the processor, perform a storage accounting of storage object consumption of the storage consumer by normalizing storage consumption data at the storage object hierarchy level across the heterogeneous storage objects.
