Whether OCS 2007 R2 can load balance? RRS feed

  • Question

  • We are planning for a new OCS 2007 R2 in our infrastructure. The plan is as follows
    1. Two OCS server
    2. One is in physical platform and second one is virtual platform
    3. Virtual is act as a DR
    4. Load balance both server with physical NLB
    5. SQL 2005 used as a database which is installed in physical platform

    Can someone suggest whether we can implement OCS in this way.

  • Not really...
    OCS is not supported in a virtual environment!

    DR must be implemented in a totally different manner
    You will find more info on DR in the Backup/Restore guide

    I hope you are talking about a HWLB (Hardware Load Balancer)

    SQL however is supported to be virtualized (but the size of you company must be taken into account when considering this)

  • Thanks for your reply.
    Instead of keep DR server separatly we are planning Active Passive load balancing by using HWLB. So we are planning Passive server keep it in virtualisation platform. Is it possible to implement?

  • Unlike classical Windows Fail-over clustering, there is no concept of active/passive load balancing in R2 front-end server pools with HLB. For multiple R2 enterprise server pools with collocated configuration, the hardware load balancers will work with the servers in the pool to direct incoming traffic to a server with sufficient capacity to handle the request.

    Note that Network Load Balancing is not a supported option for production.

    Hope this helps. Please keep us posted. Thanks.

  • You DR solution could be :
    Do a P2V conversion of your Pool
    Keep it as a Cold Standby, but you will loose new settings for users since the P2V

    Still you should backup your DB with a tool and  restore it to the DR Server
    Check the Guide I talked about earlier it is still the same concept
