Abstract: A distributed storage system has a plurality of instances. A computer system simulates the state of the distributed storage system. The system obtains a current state of the distributed storage system and replication policies for objects in the distributed storage system. Each replication policy specifies criteria for placing copies of the relevant objects among the plurality of instances. The system receives proposed modifications to the state of the distributed storage system and simulates the state of the distributed storage system over time based on the current state of the distributed storage system, current statistical trends in the state of the distributed storage system, the replication policies for the objects in the distributed storage system, and the proposed modifications to the state of the distributed storage system. One or more reports are generated relating to time evolution of the state of the distributed storage system based on the simulation.
