Configuring CARP (Enterprise Edition)

ISA Server 2006 Enterprise Edition only

When you enable Cache Array Routing Protocol (CARP), the cache drives on all the servers in the array are treated as a single logical cache drive. In this way, cached objects can be efficiently distributed among the member servers.

To enable CARP, you must do the following:

  1. Enable CARP for the array-level network. CARP will be applied to objects cached for requests on this network. For instructions, see Enable CARP.
  2. (Optional). Configure the load factor for the array members. By default, the load factor on each server is set to 100. You can configure a higher load factor, if you want more objects to be cached to a specific server. Alternatively, configure a lower load factor if fewer objects should be cached to the server.
    For instructions, see Configure load factor.
  3. CARP functionality requires that the network with the intra-array address for this array listens for Web Proxy client requests. For instructions on how to configure this network to listen for Web Proxy client requests, see Listen for Web Proxy client requests.
