Chassis management

IBM® Flex System Manager management software can manage multiple Flex System Enterprise Chassis, including the security policies and user registries on the Chassis Management Modules (CMMs) in those chassis.

IBM Flex System Manager management software supports both local and external user registries. A local user registry operates within the IBM Flex System Manager management software. An external user registry is a registry outside of your IBM Flex System Manager.

The management software provides a user authentication and authorization system that can be used by all Flex System Enterprise Chassis components.

For each chassis that is managed by the management software, you can select whether security policy and user accounts are managed centrally by the management software (centralized management) or in a distributed fashion on each CMM (decentralized management). Decentralized management refers to security policies and user accounts defined on each CMM or security policies and user accounts in an external user registry (for example, on a Windows Active Directory server).

Note: Whether using Centralized or Decentralized management, a CMM can be managed by only one management node at a time.
