Abstract
Techniques and architectures to estimate storage system capacity are disclosed. Deduplicated data and an index of object entries are maintained in a storage system. The entries contain shallow reference counts. The shallow reference count values indicate a number of parent metadata objects that hold a reference to corresponding object. One or more tree milli-indices and one or more node milli-indices of object entries are maintained in the storage system. The entries correspond to a subset of objects stored in the storage system. The entries also have truncated object signature values and deep reference count values for the corresponding objects in the storage system. A capacity utilization of the storage system is determined based on analysis utilizing the deep reference count values to perform various multiset operations.
