Dell PowerProtect DD Management Center (DDMC) 7.9 Installation and Administration Guide

Configuring DD Boost stream limits

You can configure stream warning limits for each Storage Unit for four items: Read, Write, Replication, and Combined. When any of these stream counts exceeds the warning limit, an alert is generated.

1. Select Set Limits from the DDBoost Streams tab of the Edit Tenant Unit dialog [which you can get to by selecting Administration > Multi-Tenancy, then selecting a Tenant Unit and Edit Tenant Unit (yellow pencil)].
2. In the Set DDBoost Stream Limits dialog, enter values for the Read, Write, Replication, and Combined stream limits. Do not exceed the DD system limits. Also note that a single value cannot be larger than the combined limit.
   For hard limits there are two additional validation rules:

   • The combined limit is also no greater than the sum of the other hard limits (if it is, you will hit one of the other limits first and never the combined limit).
   • The combined limit is less than the maximum individual hard limit (if it is, you will never hit that individual limit, that is, you will always hit the combined limit first).
3. If the limits are surpassed, an alert will be generated by the system.
4. Select Set.
