Question about HA active/standby with hard-wired failover

merikatori,

 

 

3 - serial cable failover just detects voltage and any loss of voltage will cause a failover.

 

2 - it's the active appliance that makes the decision - one of it's deamons will be monitoring VLAN failsafe and will cause the appliance to reboot, restart, failover etc. See System, HA, Fail-Safe, System for a list of which daemons cause which action.

 

1 - does it mean connection mirroring? I didn't think this went over the HA network failover interface.

 

 

If you've got hardware failover (f5's recommended failover of choice) then network failure is pretty redundant. It would still require hardware failure too to trigger the Active going to Standby (and vice versa).

 

 

Hope this helps,
