Create LUN: Data Protection

Allocate capacity for clones of the LUN to ensure protection of the LUN data.

To make sure that enough storage space exists for clones of a LUN, you must allocate a repository for clones when you create the LUN.

To set sufficient capacity, use a value equal to the source LUN capacity multiplied times the number of Clone LUNs multiplied times the maximum rate of change.

Click the Data Protection tab.
Select Single Tier or Auto Tier.
Click Enable Clones.
Adjust the value in the Maximum Capacity field by clicking the Increment or Decrement arrow or entering a new value in the field.
The default value is the available capacity for Clone LUNs, which corresponds to the LUN capacity you set as the Addressable Logical Capacity for the LUN in the Quality of Service tab.
If you want to use the same QoS settings for the clone LUN, click the Match Repository QoS to Tier QoS. If you do not want to use the same QoS settings for the clone LUN, then complete the following fields:
1. Select the Storage Domain.
2. Select the Storage Class.
3. Select Basic or Advanced.
  Basic
  
  Complete these fields: Typical Access, I/O Bias, Redundancy, and Priority Level.
  
  Advanced
  
  Complete these fields: RAID Level and Priority Level.
Click OK to save the LUN.

Clicking OK saves the LUN with the new capacity allocation and the attributes you set in the Quality of Service and Mapping tabs.
