Policy managers and their functions

    Requires Free Membership to View

The types of activities that can be automated include:

  • Job and task scheduling
  • Application and cluster availability management
  • Path and component management
  • Data discovery and data classification
  • Data migration and archiving
  • Backup and replication
  • Change control and management
An event notification or error detection usually triggers rules within the policy manager; rules may be defaults supplied by the vendor or rules created by the user. Policies are the algorithms or rules on how and when to respond to different conditions. The ability to customize rules within the policy manager will vary among products; some support importing taxonomies for specific types of data. Interoperability among different policy managers will also vary because some work only in the context or domain of what they can see and manage. For example, host-based policy managers should be able to enforce policy across different storage systems. On the other hand, storage system or appliance-based policy managers enforce policies across the technologies, domains and resources they can see. While there can be a common set of business rules or policies pertaining to BC and DR, including RTO and RPO, among others, those rules may need to be programmed into or taught to different policy managers. Hence, the basic rules may be common, while the language, syntax or rules may be different among policy managers, resulting in multiple policy repositories.
