Replication network recommendations

Network and port standards for data replication

  • Purchase the fastest Ethernet Network Interface Cards (NICs) compatible with your server.
  • For high availability, purchase 2 NICs per server. We recommend 100GbE NICs. The model of NICs depends on the server hardware.
  • For failover between 2 servers, the NICs can be directly connected to each other.
  • For failover across 3 or more servers, the NICs must be connected to a compatible network switch that runs at the same speed or faster than the NICs.

Port access

For replication clients add incoming network port rules for:
  • Custom TCP port 5597
    This is the FairCom DB ISAM port. It depends on the server name and can be found in the CTSTATUS log file.
  • Custom TCP port 6597
    This is the FairCom DB SQL port. It can be found in the ctsrvr.cfg config file.
  • HTTP port 80 or HTTP port 443
    This is only needed if you want to access the web tools.
