PowerProtect Data Manager 19.10 Administration and User Guide

Create a storage unit

Directly create a storage unit through the PowerProtect Data Manager UI for use with protection policies.

1. From the left navigation pane, select Infrastructure > Storage.
   The Storage window appears.
2. On the Protection Storage tab, select a storage system, and then select More Actions > Manage Storage Units.
   The Storage Units page opens and displays a list of the storage units under the control of PowerProtect Data Manager.
3. Select Add.
   The Create Storage Unit or Create Mobile Storage Unit dialog box opens.
4. Type a name for the new storage unit.
5. For mobile storage units in system pools, select a Network Group.
   Network groups are configured in DDMC to provide access to the system pool over different physical or virtual networks. A network group contains information about the IP addresses for the pool members and the IP address that clients use for access to the system pool.
6. Set the capacity and stream quotas that restrict the storage unit resource consumption.

   There are two kinds of quota limits—hard limits and soft limits. You can set either a soft or hard limit or both a soft and hard limit. Both values must be integers, and the soft value must be less than the hard value.

   NOTE When you set a soft limit and the limit is reached, an alert is generated but data can still be written. When you set a hard limit and the limit is reached, data cannot be written. All data protection operations fail until data is deleted from the storage unit. The PowerProtect DD Virtual Edition Installation and Administration Guide for the appropriate platform provides more information about quota configuration.
   1. Capacity Quota—Controls the total size of precompression data that is written to the protection storage.
   2. Stream Quota—The number of concurrent streams allowed during data protection operations. Setting a Stream Quota limit can help ensure that performance is not impacted negatively when a data protection operation consumes too many resources.
7. Select Save.
