    Load Balancing Sharepoint 2010

    The Basics

    Load balancing is required for the Front-end Web Servers to provide performance and resilience for users connecting to the Sharepoint farm.

    For the middle (application) tier, multiple application servers running the same service applications are load balanced by default and there is no external load balancing requirement.

    Sharepoint 2010 is based on IIS and associated technologies at the top / middle tier and Microsoft SQL Server for back-end storage. Therefore, load balancing Sharepoint 2010 is relatively straight- forward, but to provide a resilient and robust Sharepoint system, it's important to consider Microsoft's various architectural recommendations, best practices and guidelines when designing your Sharepoint Infrastructure.

    TCP Ports

    Sharepoint uses a range of ports for internal and external farm communication. The ports that need to be load balanced are those used in communications between external users and the Front-End Web Servers as shown in the following table:

    TCP Port Use Description

    80 Web Front-End Standard HTTP port used for Web Application / Site access

    443 Web Front-End Standard HTTPS port used for Web Application / Site access

    8080* Central Admin Custom port for Central Administration Website (HTTP)

    8443** Central Admin Custom port for Central Administration Website (HTTPS)

    * During the Sharepoint 2010 installation the installer suggests a random HTTP port for the Central Administration website. In the lab environment used for this guide, this was set to port 8080

    ** In the lab environment, the Central Administration website was extended to the Extranet zone and configured for HTTPS on port 8443. System administrators are then able to access the Central Administration website over HTTP and HTTPS

    For a full Sharepoint Server port list, please refer to:

    Persistence (aka Server Affinity)

    Enabling persistence ensures that clients continue to connect to the same server when connecting into theSharepoint farm. We recommend using IP persistence for simplicity and compatibly across protocols.

    Load Balancer Virtual Server (VIP) Requirements

    It is possible to configure a single VIP that includes all required ports as listed in the table above. However, to enable more granular control and improved health-check monitoring, multiple Virtual Servers are recommended. The list below shows the general approach used in this guide:

  • Hallo Andre,

    ich denke dieser Blog Eintrag sollte deine Fragen genau beantwortet. Direkt von der Quelle und in Bezug auf SharePoint ;)

  • Vielen Dank,

    da das Thema nun schon etwas länger hier steht wurde bei uns erstmal eine andere "Lösung" implementiert. Aber die genannten Artikel sind sehr gut.

    Vielen Dank für die Ratschläge.
