N+1 Failover
N+1 Failover is a feature of EQ/OS 10 where the failover configuration consists of multiple active peers ("N") plus
1 passive peer. In this type of failover configuration, the Equalizer clusters are instantiated on all "N"peers and
organized into failover groups. If the passive, or backup peer's connectivity for a failover group's resources is
judged to be "healthier" that the peer on which the group is running, then the group fails over to the passive peer,
which becomes the Primary peer.
N+1 failover can be configured between two EQ/OS 10 Systems only.
Failover Modes
The Failover Mode is the current failover condition of an Equalizer peer or Failover Group when configured into
Active/Passive, Active/Active, or N+1 failover configuration. It is shown both in the an eqcli display and on the
GUI.
The following table lists the possible Failover Modes that can be displayed along with a description of each.
