CA Access Control Enterprise Management uses mirrored sites to provide high availability deployments. Mirrored sites are fully redundant facilities with full, real-time information mirroring and are identical to the primary site in all technical aspects. Data is processed and stored at the primary and mirrored sites simultaneously.
Mirrored sites employ an active-passive deployment for failover. An active-passive deployment includes two or more data centers, with one actively processing requests and the other ready to service requests if the active one fails. The clustering solution software that you select is responsible for controlling the active and passive servers and switching between them in case of failure.
In an active-passive deployment, the active server is referred to as the primary server, and the passive server is referred to as the secondary server.
