Dell PowerStore Configuring Volumes
Performance policies
A performance policy specifies I/O performance requirements for PowerStore storage resources.
PowerStore provides three predefined performance policies:
- High
- Medium (default)
- Low
It is recommended that you associate the high-performance policy with critical applications only. Reserving a high-performance policy for critical applications ensures that those critical applications are not competing for I/O against less-critical applications.
Performance policies for storage resources
You can assign performance policies to volumes, volume groups, and thin clones when you provision them or modify their configuration.
If you do not explicitly configure a performance policy for a resource, the resource is associated with a Medium performance policy.
