Abstract:
1. A machine implemented method, comprising: monitoring a number of input/output (I/O) requests that are being processed by a storage system node during a time interval for reading and writing information at a source storage array and a latency in processing the I/O requests by the storage system node, where the latency indicates a delay in processing the I/O requests; comparing the number of I/O requests with a first threshold value; increasing transfer of replicated information from the source storage array to a destination storage array by a first value, when the number of I/O requests has not reached the first threshold value; comparing the latency with a second threshold value; and increasing transfer of the replicated information from the source storage array to a destination storage array by a second value that is less than the first value, when the latency has not reached the second threshold value.
