Configuring Stream Randomization
When a storage policy is configured to use more than one device stream, it is important that the device streams are equally used. If you enable stream randomization, the system chooses the device 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 of 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. Refer to Tunable Parameters for more information on tuning stream randomization.
- From the CommCell Browser, expand Policies > Storage Policies.
- Right-click the appropriate storage policy copy, and then click Properties.
- Select the Enable Stream Randomization check box.
- Click OK.
