Maximum Large Server Farm with a SQL Cluster<br />

Large server farms scale out well. The maximum large server farm with SQL cluster<br />

is the largest single farm deployment you can have. You can scale a large farm to<br />

any configuration between the minimum large server farm <strong>and</strong> the maximum larger<br />

server farm, but because of space constraints, only the minimum <strong>and</strong> maximum configurations<br />

are presented in this. For more information on large farm scaling, please<br />

see Chapter 11.<br />

The maximum supported large server farm with a SQL cluster consists of eighteen<br />

servers: eight load-balanced front-end Web servers, four search servers, four<br />

indexing management servers, <strong>and</strong> two systems running SQL servers acting as an<br />

active/passive cluster. Additionally, a nineteenth server running the optional document<br />

management components can be used. The maximum large server farm with<br />

SQL cluster is a highly available SharePoint Portal Server solution supporting large<br />

organizations with moderate to heavy usage. It provides protection from multiple<br />

points of failure. If you need to scale out beyond the maximum large server farm<br />

environment, you will need to use multiple farms <strong>and</strong> use inter-farm shared services<br />

to connect the farms. Inter-farm shared services is described in Chapter 14, “Shared<br />

Services.”<br />

This type of farm environment was not tested for this chapter, so no specific<br />

hardware recommendations are provided. If you are building a maximum large<br />

server environment, you should contact your hardware vendor, <strong>Microsoft</strong> representative,<br />

or both to discuss hardware recommendations.
