ABSTRACT:
Embodiments include methods, apparatus, and systems for determining bandwidth in storage systems. One embodiment includes a method receiving a recovery point objective (RPO) for a disaster recovery (DR) system that uses asynchronous replication. The method then computes a queue depth for queued data waiting to be transmitted to a secondary storage location and uses the RPO and the queue depth to calculate a bandwidth for transmitting data from a first storage location to the secondary storage location.
