[EXCH2010] Best way to implement continuity of service ? RRS feed

  • Question

  • Hello,

    I have one server running in house with Exch2010 SP2, working perfectly.

    I am looking to get something in my Datacenter that could provide me some service in case the first one crash and that automatically.

    I am not sure that if I just duplicate roles it will accomplish what I am looking for. I also looked over an Hybrid configuration with office365 but the confidentiality in my company impose that we host all our data.

    Any idea ?

     

    Thanks

  • Hi,

    If you installed the enterprise edition of Windows on the Exchange server you can add another enterprise edition server, Install Exchange on this server, create a DAG and a CAS array, create database copies on the new server and use a hardware loadbalencer to loadbalance all client requests.

    If the server is the standard edition you need to install 2 new enterprise edition servers and proceed as mention above

  • I do have an Exchange 2010 enterprise Ed and I plan to have the same one installed on the backup site, but there is one details about that is still avoiding me :

    If my fist site is unavailable, let say my router is down, how the load balancer will be able to transfert the request to the backup site ?

    Do they operate on the DNS level and then interact with Exchange ? If then what kind of brand offer that kind of services ?

     

    Thanks

    If the load balancer is inaccessible that's not going to happen.

    You're really asking questions about networking, not Exchange.
     
    DNS "load balancing" really isn't load balancing at all. It's just a
    "round-robin" use of multiple resource records. Half of the queries
    will receive the address of the unavailable router.
     
    >If then what kind of brand offer that kind of services ?
     
    You really need to engage your ISP and ask about what they can help
    you with.
