Define Optional Director Topologies in Your Topology

 

Topic Last Modified: 2012-09-08

Lync Server 2013 Directors can be single-instance servers or they can be installed as a load-balanced pool of multiple Directors for higher availability and capacity. Both hardware load balancing and Domain Name System (DNS) load balancing are supported. This topic explains how to configure DNS load balancing for Director pools.

To successfully publish, enable, or disable a topology when you add or remove a server role, you should be logged on as a user who is a member of the RTCUniversalServerAdmins and Domain Admins groups. You can also delegate the proper administrator rights and permissions for adding server roles. For details, see Delegate Setup Permissions in the Standard Edition server or Enterprise Edition server Deployment documentation. For other configuration changes, only membership in the RTCUniversalServerAdmins group is required.

This topic describes the steps to define and publish the topology for the two Director topologies:

  • To define the Director (single instance)
  • To define the Director (multiple Director pool)

  1. Start Topology Builder: Click Start, click All Programs, click Microsoft Lync Server 2013, and then click Lync Server Topology Builder.

  2. On the welcome page, click Download Topology from Existing Deployment.

  3. In the Save Topology As dialog box, type the name and location of the local copy of the existing topology, and then click Save.

  4. Expand the site in which you plan to add the Director, right-click Director pools, and then click New Director Pool.

  5. In the Define the Director pool FQDN dialog box, do the following:

    • In Pool FQDN, type the FQDN for the Director pool.
    • Click Single computer pool, and then click Next.
  6. In the Define the file share dialog box, do one of the following:

    1. To use an existing file share, click Use a previously defined file share, select a file share from the list, and then click Next.
    2. To create a new file share, click Define a new file share, type the FQDN for the location of the file share in File Server FQDN, type the name of the share in File Share, and then click Next.
    importantImportant:
    The file share that you specify or create in this step must exist or be created prior to publishing the topology.
    The file share assigned to a Director is not actually used, so you can assign the file share of any pool in the organization.
  7. In the Specify the Web Services URL dialog box, in External Base URL, specify the FQDN for the Directors, and then click Finish.

    importantImportant:
    The name must be resolvable from Internet DNS servers and point to the public IP address of the reverse proxy, which listens for HTTP/HTTPS requests to that URL and proxies them to the external Web Services virtual directory on that Director.
    warningWarning:
    If you have more than one Front End pool or Front End Server the external Web services FQDN must be unique. For example, if you define the external Web services FQDN of a Front End Server as pool01.contoso.com, you cannot use pool01.contoso.com for another Front End pool or Front End Server. If you are also deploying Directors, the external Web services FQDN defined for any Director or Director pool must be unique from any other Director or Director pool as well as any Front End pool or Front End Server. If decide to override the Internal web services with a self-defined FQDN, each FQDN must be unique from any other Front End pool, Director or a Director pool.
  8. Publish the topology.

  1. Start Topology Builder: Click Start, click All Programs, click Microsoft Lync Server 2013, and then click Lync Server Topology Builder.

  2. On the welcome page, click Download Topology from Existing Deployment.

  3. In the Save Topology As dialog box, type the name and location of the local copy of the existing topology, and then click Save.

  4. Expand the site in which you plan to add the Director, right-click Director pools, and then click New Director Pool.

  5. In the Define the Director pool FQDN dialog box, do the following:

    • In Pool FQDN, type the FQDN for the Director pool.
    • Click Multiple computer pool, and then click Next.
  6. In the Define the computers in this pool dialog box, do the following:

    • Specify the computer FQDN of the first pool member, and then click Add.
    • Repeat the previous step for each computer that you want to add. When you are finished, click Next.
  7. In the Define the file share dialog box, do one of the following:

    • To use an existing file share, click Use a previously defined file share, select a file share from the list, and then click Next.
    • To create a new file share, click Define a new file share, type the FQDN for the location of the file share in File Server FQDN, type the name of the share in File Share, and then click Next.
    importantImportant:
    The file share that you specify or create in this step must exist or be created prior to publishing the topology.
    The file share assigned to a Director is not actually used, so you can assign the file share of any pool in the organization.
  8. In the Specify the Web Services URL dialog box, in External Base URL, specify the FQDN for the Directors, and then click Finish.

    importantImportant:
    The name must be resolvable from Internet DNS servers and point to the public IP address of the reverse proxy, which listens for HTTP/HTTPS requests sent to that URL and proxies them to the external Web Services virtual directory on that Director pool.
    warningWarning:
    If you have more than one Front End pool or Front End Server the external Web services FQDN must be unique. For example, if you define the external Web services FQDN of a Front End Server as pool01.contoso.com, you cannot use pool01.contoso.com for another Front End pool or Front End Server. If you are also deploying Directors, the external Web services FQDN defined for any Director or Director pool must be unique from any other Director or Director pool as well as any Front End pool or Front End Server. If decide to override the Internal web services with a self-defined FQDN, each FQDN must be unique from any other Front End pool, Director or a Director pool.
  9. Publish the topology.
