SnapManager sets a default policy for fractional space reservation. You can use the default values, or change the values that would apply to all storage system volumes.
The default fractional space reservation policy is automatically enabled for any traditional or flexible volume that has an overwrite reserve that is set to less than 100 percent. The volume must also contain LUNs that store Exchange database files, Exchange transaction log files, or SnapManager SnapInfo directories.
- Default policy
- You can use the default policy as-is, allowing the factory default values to be applied to all volumes that contain fractional space-reserved LUNs.
- Default policy with customized settings
- Optionally, you can customize the default policy that is applied to all storage system volume that contains fractional space-reserved LUNs.
- Volume-specific policies
- Optionally, you can override the default policy for any particular volume that contains fractional-space-reserved LUNs, by applying a custom policy.
