Visualization, Performance, and Fault Manager (VPFM) is Active-Active Geographic Redundancy-aware. VPFM is configured to communicate with primary and secondary System Manager servers. VPFM communicates with System Manager servers for Authentication and Authorization (A&A) operations, such as SSO and RBAC. Usually, the element leverages A&A services from the System Manager server which is closest to the element regardless of whether the server is in the primary or the secondary mode. The secondary System Manager can serve A&A requests in both the standby and active modes.

VPFM leverages System Manager for Common Service Client (SMGR-CS Client) that provides adopters with off-box SSO and RBAC solution that works with System Manager.
