    1.OCS 2007的Edge Server 是否可以用Standard的版本來建置?

    2.若可以是否可以做NLB?

  • 您好 :

     

    首先Edge可以使用OCS標準版來建置 , 至於NLB部份一般都是規劃在內部企業版集區的OCS伺服器上 , 至於有關於Edge在負載平衡的規劃上可以參考以下原文說明 , 詳細部份可以參考OCS_EdgeServerDeploy.doc 文件.

    You can use load balancers to distribute incoming connections across multiple edge servers. If you are deploying edge servers in a scaled single-site edge topology or a multiple-site edge topology with a scaled remote site, you must deploy a load balancer for the collocated Access Edge Servers and Web Conferencing Edge Servers and the A/V Edge Servers in the perimeter network of the data center. You deploy load balancers for traffic from both the external network and traffic from the internal network. A single load balancer can be used for all three server roles; however, using separate virtual IP addresses (VIPs) for each server role is highly recommended. We recommend port 443 for all three server roles, and because a different port/IP combination is required for each server role, separate VIPs support the recommended configuration.

    For load-balanced Web Conferencing Edge Servers and A/V Edge Servers in the perimeter network of the data center, outgoing requests are connected directly to a specific Web Conferencing Edge Server or A/V Edge Server. These outgoing requests are handled as follows:

    ·         Each time an internal Web Conferencing Server starts up, it looks up the Web Conferencing Edge Servers that are configured in its environment, and then it looks up the DNS A record of each. The internal Web Conferencing Server then initiates four outbound TCP connections to the internal IP and port of each Web Conferencing Edge Server.

    ·         The load balancer for the A/V Edge Servers routes each A/V request to one of the A/V Edge Servers, which then manages the connection until it ends.

    Additional information about load balancing, including an example, is provided in the “Planning for Load Balancing” section of the Office Communications Server 2007 Planning Guide. You should use the information provided there to help you determine the appropriate configuration for load balancing. The basic requirements for load balancing are as follows:

    ·         If you want to load balance Web Conferencing Edge Servers, you must collocate each Web Conferencing Edge Server with an Access Edge Server. The A/V Edge Server must not be collocated on the same server.

    ·         The external interfaces of multiple collocated Access Edge Servers and Web Conferencing Edge Servers must be load balanced. However, only the internal interface of the Access Edge Servers in this configuration should be load balanced. The internal interface of the Web Conferencing Edge Servers must not be load balanced.

    ·         Both the external and internal interfaces of the A/V Edge Servers are load balanced.

    ·         All Access Edge Servers and Web Conferencing Edge Servers that are connected to the load balancer must be configured identically, including identical internal and external ports, Allow lists, Block lists, federated partners, internal domain lists, internal server lists, remote user settings, and proxy connections.

    ·         Certificates must be installed and configured to support load balancing (as covered later in this guide).

    ·         Federated partner Access Edge Servers, and remote user clients must target the virtual IP address used by the Access Edge Server array on the external load balancer.

    The internal next hop server (typically, a Director) must target the virtual IP address that is used by the Access Edge Server on the internal load balance

  • 你好:

     

    兩種版本都可以建立EDGE Server,不過我想Edge Server,使用standard 的授權即可,可以詢問一下你的業務。

     

    可以配合硬體設備做NLB,架構可以參考 http://technet.microsoft.com/en-us/library/bb663789(TechNet.10).aspx

  • 1. OCS 2007的Edge Server 是否可以用Standard的版本來建置?

        ANS:  首先來了解EDGE在整個OCS環境所扮演的角色(功能), 單純的EDGE並不牽涉到NLB或REDUNDANT等功能,所以並不一定需要企業版, 反之若是要求EDGE具備NLB或REDUNDANT等功能,此時就需要使用企業版.

     

    2. 若可以是否可以做NLB?

       ANS:   如上所述,標準版不提供NLB功能, 若需此功能則須購買企業版.
