Configuring CCR cluster mailbox with Replication link on secondary interface ?

    Question

  • Hi people,

    Can anyone here please let me know what is the steps that is needed to setup the Cluster Replication link in between Production Mailbox server role and the DR mailbox server role ?

    I need to create the highly available replication link / group from the Failover Cluster Management group.

    Thanks

  • Hello,

    Please make sure you use Windows 2003 or Windows 2008. If you use Windows 2003, each node must be on the same subnet and cluster communication needs to be .5 seconds for round trip communication.

    If you use Windows 2008, cluster nodes can span across multiple subnets.

    For many configurations, testing has shown that that network latency between CCR nodes should be below 50ms.

    Generally, each node of the cluster will usually have two network interfaces configured. One network interface will be used for client communications whilst the other will be used for intra-cluster communications. But we recommend you allowed additional redundant networks to be added to a CCR environment for the purposes of log shipping and database seeding.

    Here is the article for your reference.

  • If you have configured a secondary replication network and it fails, say because you changed the IP address temporarily so that the two nodes can't communicate, then it's supposed to use the primary network.

  • Thanks for the reply.

    Does this means that it requires two replication link to be defined in the Cluster Administration console ?

    One from Prod to DR and the other one is DR to prod ?

  • Cara,

    I'm using Windows Server 2008 SP2 for the Exchange Server 2007 SP3 CCR mailbox server.

    does, changing the IP address later on when the server has been running or set as the cluster going to break the Exchange Server CCR clustering ?
