Module 7: Planning Server Roles and Placement v Customization Information This section identifies the lab setup requirements for a module and the configuration changes that occur on student computers during the labs. This information is provided to assist you in replicating or customizing Microsoft Official Curriculum (MOC) courseware. Lab Setup The following list describes the setup requirements for the labs in this module. !" For each student, a Microsoft Management Console (MMC) custom console must be created. This custom console must include both the Active Directory Users and Computers snap-in and the Exchange System snap-in, and must be named your_firstname Console. !" For each student, a personalized user account must be created in the appropriate domain. This user account must be added to the Domain Admins group, and assigned a mailbox on the server running Exchange 2000 that the student is using. !" For each student, a user profile must be created on the student’s computer that enables the student to access their mailbox by using Microsoft Outlook ® 2000. !" The students sitting at the City-MBX1 computers will need the IMAP4Stresser application that is located at c:\moc\1573a\labfiles Lab Results Performing the labs in this module introduces the following configuration changes: !" Network Load Balancing is configured for the City-FE1 and City-FE2 servers. !" DNS is configured to have a front-end namespace for each routing group. !" The City-FE1 and City-FE2 servers in each routing group are converted to front-end servers. !" All mailboxes are moved from the City-FE1, City-FE2, and City-PF1 servers to the City-MBX1 server in each routing group. !" The City-MBX1 server in each routing group is configured so that the private information store databases point to the City-PF1 server in it’s routing group.

Planning Front-end/Back-end Servers ! Planning for Servers Running Active Directory ! Discussion: Planning Server Placement Microsoft ® Exchange 2000 organizations designed for the enterprise usually deploy several different servers. Although it is possible to install the entire functionality of Exchange 2000 on a single server, it is usually better to distribute the functions among several servers. Architects designing an Exchange 2000 organization need to be able to identify and plan for the deployment of each of the types of servers that a company needs. In addition to identifying server roles, the necessary planning tasks include determining the number of each type of server that a company requires, as well as where to place each server. To complete these tasks, you must understand the various roles of the different types of servers, and of the design effects associated with their deployment. After completing this module, you will be able to: !" Plan mailbox servers and public folder servers. !" Plan connector servers. !" Plan front-end/back-end servers. !" Plan servers running the Microsoft ® Active Directory ™ directory service. !" Identify the factors to be considered when designing server placement. Topic Objective To provide an overview of the module topics and objectives. Lead-in In this module, you will learn about the Exchange 2000 server roles, and how to plan and place servers for an effective Exchange 2000 organization. 2 Module 7: Planning Server Roles and Placement Introduction to Planning Server Roles and Placement User Internet Front End Servers Back End Servers Mailbox Server Connector Server Internet User Mailbox Server Public Folder Server Although each server running Exchange 2000 often performs several roles in a smaller organization or in a remote office, it is often preferable to dedicate servers to perform specific roles. Distributing functions among several different servers enables you to provide faster response time and reduced downtime. Distributing roles also helps prevent servers from becoming overloaded, and removes the dependencies between services. Planning server roles and placement will help you decide which hardware to purchase and will affect the performance of your messaging system. It is important to have your budget settled prior to planning your server roles, because dedicating servers to specific roles may significantly increase the number of servers that you will need to purchase. Topic Objective To outline the different types of servers that a company may deploy. Lead-in There are several ways to deploy servers running Exchange 2000. Module 7: Planning Server Roles and Placement 3 # ## # Planning Mailbox Servers and Public Folder Servers ! Capacity Planning ! Planning Considerations ! Planning Storage Needs ! Partitioning Databases Developing an effective design strategy for mailbox servers and public folder servers involves taking into account the capacity that each server can handle, as well as such considerations as service level agreements, retention policies, and storage needs. Topic Objective To outline the design considerations that are associated with planning mailbox and public folder servers. Lead-in There are several design considerations to take into account when planning mailbox and public folder servers. 4 Module 7: Planning Server Roles and Placement Capacity Planning Storage limits Time required to perform a backup Time required to recover from a disaster Time required to restore a single database Time required to restore a single mailbox Capacity Planning for Mailbox Servers Capacity Planning for Mailbox Servers Capacity Planning for Mailbox Servers Service levels Response time Capacity Planning for Public Folder Servers Capacity Planning for Public Folder Servers Capacity Planning for Public Folder Servers The number of users and public folders that each server can support depends primarily on the usage profile for each user. Mailbox Servers The most important factors to consider when calculating the number of mailboxes to store on each server are: the storage limits, the time required to perform a backup, the time to recover from a disaster, the time to restore a single database, and the time to restore a single mailbox. Public Folder Servers Service levels and response time are the primary factors to consider when determining whether to dedicate a server to public folder storage. For example, if your company builds custom applications into multiple public folder hierarchies, it is recommended that you place these hierarchies on a separate server so that people gaining access to these custom application folders do not increase the response time for people checking their mailboxes. Topic Objective To provide capacity planning information for mailbox and public folder servers. Lead-in The number of users and public folders that each server can support depends primarily on the usage profiles for each user.
