Dell PowerProtect Data Manager Appliance 5.13.0.0 Administrator Guide for DM5500

Edit storage unit

Configure the settings for an existing storage unit through the PowerProtect Data Manager Appliance UI. You can also view a list of protection policies that target the storage unit.

1. From the left navigation pane, select Infrastructure > Storage.
   The Storage window appears.
2. On the Summary tab, in the Active Tier section, click the three vertical dots.
3. From the menu, select Storage Units.
   The Protection Storage > Storage Units page appears and displays the list of storage units.
4. To view the details or usage for a storage unit, select for that storage unit.

   The Details pane opens and displays the name, type, capacity, quota information, and a list of protection policies that currently target the storage unit.

   The storage unit may contain copies from protection policies that no longer target the storage unit.

5. Select a storage unit from the list, and then click Edit.
   The Edit Storage Unit dialog box appears.
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.
   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. Set a Retention Lock Mode from the available modes: None or Governance.

   This field displays only the licensed and enabled options for the selected protection storage system. If no retention lock modes are enabled, the only option is None.

8. Select Save.
