Load Balancing and High Availability for RDWeb/Gateway/Connection Broker ?

    Question

  • What options are available please to provide high availability for the RDWeb/RD Gateway and RD Connection Broker server roles running on Win 2008 R2?   

    What we'd like to achieve is to use some sort of load balancer in front of some virtual RDWeb, RD Gateway and Connection Broker servers to provide load balancing and resiliency so in the event of a host/vm failure or application crash so that users are automatically diverted to the surviving server.       we'd prefer to use some kind of proper load balancer (hardware/software) instead of Windows NLB.

    thanks.

  • Hi Andy,

    I am currently testing a hardware load-balancer frem KEMP Technologies. I know it can do web server load-balancing/fail-over, it is also able to do terminal server session load-balancing, thats the thing I am currently testing, you should be able to use this box as "Connection Broker".

    Have a look at their web site: http://www.kemptechnologies.com

  • Hi,
     
     
    Based on my knowledge, you can set up a RDS host farm and then the DNS will round robin to retrieve one of available RD host servers.
     
    Create a Load-Balanced RD Session Host Server Farm by Using RD Connection Broker
    http://technet.microsoft.com/en-us/library/cc753891.aspx
     
     
    Also, The Connection Broker will provide load-balancing independent of how the client makes the connection (using RR DNS or NLB) because the client connection will be routed to the least busy RDSH server. To avoid this issue, you can deploy the NLB and SBLB:  This requires Windows Server 2008 Terminal Services and Windows Server 2008 Session Broker.  Due to the existence of the NLB heartbeat, there is better detection of offline servers.
