Hi to all,
I can't set a storage policy with more than 50 streams. I currently have a version 11 SP20 installed.
I have tried with various types of libraries (tape, disk library). The commserve has been updated several times over the years (I think the oldest was a SP8).

Limit 50 streams on Storage Policy
Best answer by Aplynx
Do you have a limit set in the Media Management Configuration?
| Maximum number of parallel data transfer operations for deduplication engine | Definition: Specifies the number of streams used by backups, auxiliary copy operation, and so on, to access the deduplication database. Default Value: 200 (Note: If CommServe is installed or upgraded from Commvault package earlier than SP2 release, then the default value will appear as 50.) Range: 0 to 600 Usage: The number of streams to DDB should not exceed the maximum range as it may degrade the performance. Note that, this parameter has precedence over the device streams specified on the Storage Policy properties. For example, if the storage policy is set to 100 device streams and this parameter is set to 50, then only 50 device streams will be used to access the DDB. |

Hi Gabriele,
Do you see any error while setting the streams or GUI just doesn’t let you go beyond 50?
If you are getting a warning popup when setting the streams more than 50, you can still click “Yes” and override the warning (if you are sure your Storage policy can handle those many streams).
Thanks,

Hi
Could you share a screenshot of this please?
Also, Are you using the Java CommCell Console on the CommServe itself or from a remote machine? - If remote then check its up to date, or load it on the CS.
Best Regards,
Michael
