Exchange 2010 two servers only and at different networked sites


  • One server at Colo will be the main mailbox, CAS and HUB Transport the second server at a different site will be for emergency failover

    one question is how to setup the NICs I can't find a complete answer anywhere this is my guess

    we only want to failover  to the secondary server if the primary server fails


    nic 1 (MAPI) mask

    nic 2 (Replication) mask

    plus a Witness server at this site

    secondary server

    nic 1 (MAPI) mask

    nic 2 (Replication) mask

    does this config, make since?

    Let me know if you need more info.

  • If they use the same path then not really, however if could effect MAPI performance say if you seed over the MAPI network rather than the Repl network.  I would still create 2 for the different traffic.
