Dear Experts, Kindly please advise for Historian Server redundant (primary & secondary) that link together with CCN (consistency control network) network, could it be only connected by ethernet cable between 2 historian server (without switch) ? Please advise Thanks
A dedicated 1 Gbps network (Consistency Control Network) connection is required in High Availability solutions to connect the redundant 800xA History servers for data synchronization.
This network can be either through a Switch, (typical), or with a cross-over CAT-5 cable, depending on the physical conditions of the installation. Check the manual 2PAA107280-610A page 15 for a simplified drawing of the typical network connections including the CCN and NLB networks.
