How the connection types are used
A multipath HA configuration uses primary, redundant and standby connections to ensure continued service in the event of the failure of an individual connection.
The following table outlines the connection types used for multipath HA for HA pairs , and how the connections are used:
|Connection type||How the connection is used|
|Primary connection||For normal operation, used to serve data (load-balanced with redundant primary connection).|
|Redundant primary connection||For normal operation, used to serve data (load-balanced with primary connection).|
|Standby connection||For normal operation, used for heartbeat information only. After a takeover, assumes role of primary connection.|
|Redundant standby connection||Not used for normal operation. After a takeover, assumes role of redundant primary connection. If the standby connection is unavailable at takeover time, assumes role of primary connection.|
