Client Access Availability and Scalability
Applies to: Exchange Server 2010 SP3, Exchange Server 2010 SP2
When you plan the deployment of your Exchange Server 2010 organization, performance and scalability are two important considerations. It's very important to estimate your Exchange 2010 Client Access server capacity needs. The Client Access server is the entry point for all users. In addition, the Client Access server hosts important services that are used by the other Exchange server roles. For information about the relative CPU weights of different protocols on the Client Access server, see White Paper: Understanding Granular and Relative Costs of Client Access Server Workloads In Exchange Server.
