When a storage policy is configured to use more than one data stream, it is important that the data streams are equally used. If you enable the stream randomization feature, the system chooses the data streams randomly. This increases the rate of data transfer by copying data from different streams in parallel.
You configure the tuning parameters to evenly distribute the data across all the streams. You can specify the interval to check the data size in the streams and the threshold to decide data distribution among the streams. For more information about tuning stream randomization, see Tunable Parameters.
