A performance policy specifies I/O performance requirements for PowerStore storage resources.
PowerStore provides three predefined performance policies:
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.
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.
