Primary Site Fault Tolerance

In a
CA PAM
cluster, the primary site makes fault tolerance decisions that are based on its quorum. For more information about the quorum, see Primary Site Recovery. The size of the primary site determines the quorum. The quorum determines its fault tolerance, or how many members the primary site can lose and continue normal operations.

The size of the primary site determines the quorum. The quorum determines its fault tolerance, or how many members the primary site can lose and continue normal operations.
To ensure primary site fault tolerance, we recommend at least three members at a primary site. If the entire cluster has only two members, do not put both members in the primary site. We recommend a 1 x 1 configuration (one member at the primary site and one member at secondary site).
