In an HA configuration, the two SBC platforms are connected to each other with the two HA ports using a pair of GigE cables. The connection provides both box-level and port-level redundancy. The HA pair consists of eight management ports; four ports each per platform. When switchover occurs, the logical management address follows the currently active server. The packet ports, the MAC and IP addresses float between the HA pair (are replicated from active to standby on switchover).
A logical management address is the IP address associated with a Logical Management IP Interface previously created using EMA or CLI.
Connect HA cables between the HA pair as shown:
Active HA0<--------->Standby HA0
Active HA1<--------->Standby HA1
The SBC will fail to pair with a machine that is not functionally equivalent in an upward compatibility configuration. During system installation and startup, make sure that the servers are designed to operate together and support full redundancy and high availability. Also, an HA pairing between SBC 5210, SBC 5200, SBC 5110, SBC 5100, SBC 5400 and SBC 7000 is forbidden.
