Abstract
In an active-active replication environment in which sequential read IOs are distributed across storage array ports and replicas, a first read data size controls selection of a different path to a currently targeted replica to distribute sequential reads across storage system ports and a second read data size controls when a different replica is selected to distribute the sequential reads across storage systems. The storage arrays that maintain the replicas are phase-coordinated to pre-fetch only sequential data that will be accessed in the near future from their local replica. For example, a first storage array prefetches sequential data from a first replica in chunks corresponding to the first data size until sequential data corresponding to the second data size has been prefetched, skips sequential addresses corresponding to the second data size, and prefetches sequential data corresponding to the first data size that is next in sequence relative to the skipped sequential addresses.
