6.5 Controller Fault Tolerance
The threshold for controller fault tolerance is 2n+1, where n is the number of failed controllers
allowed in an active team. HP VAN SDN Controller teaming supports a team of three controllers.
In a team of three controllers, n = 1; one controller in a team of three can fail without suspending
team operation. If one such controller does go down, a stateful failover occurs, in which the
remaining two members resume together from the point of failure, and the team continues to
operate. As long as any two of the teamed controllers in the network are active, the network remains
in a managed state. If a second controller in the team fails, then n exceeds the maximum allowed,
and the remaining controller transitions to a SUSPEND state. When at least two controllers in the
team become active, team operation resumes, with one of the controllers operating as the team
leader.
NOTE: In teamed controller operation, maintaining the integrity of the controller state information
requires that a minimum of two controllers in a team of three must be active at all times. The failure
of all but one of the controllers places the entire team in a SUSPEND state, and the domain serviced
by the team becomes unmanaged. (The remaining teamed controller does not operate in standalone
mode.)
