Appendix C: Fourth Coffee Case Study 1 General Information Introduction You have been hired by Fourth Coffee to design their implementation of Microsoft ® Exchange 2000 Server. You have been asked to provide a design that includes support for their wide area network (WAN) links, messaging infrastructure, directory design, and reliability needs. Background Fourth Coffee is a privately held company that has been in business for 50 years. Fourth Coffee’s business is the importing and processing of specialty coffee beans. Company Profile The company employs 3,000 employees. The company has five offices, which are all located within the United States. The company’s headquarters is located in Portland, Oregon. The following table lists the locations of all five offices and the number of employees retained by each office. Office location Number of employees Portland, Oregon 1,800 Miami, Florida 250 Buffalo, New York 300 San Diego, California 400 Dallas, Texas 250 Because the nature of Fourth Coffee’s business requires frequent international travel and frequent customer meetings, all employees in the company except those in administrative support positions have portable computers. Factors That Influence Business Strategies The owners of Fourth Coffee believe that their company's business is coffee beans—and not technology. Therefore, the owners want to ensure that any expenditure made for additional technology is absolutely necessary. This does not mean that additional services and equipment cannot be purchased, only that each purchase must be fully justified. 2 Appendix C: Fourth Coffee Case Study IT Environment Overview Fourth Coffee currently uses an outdated version of Lotus cc:Mail. Lotus cc:Mail is only used for basic mailbox configurations. All network servers are running Microsoft Windows ® 2000 Server, and the Microsoft Active Directory ™ directory service is running in native mode. All client computers on the network are running Microsoft Windows 2000 Professional. The company wants to use Microsoft Outlook ® 2000 as the standard messaging application. Because the company’s IT group is small, Exchange 2000 Server management should be simplified wherever possible. For example, properties should be configured on the entire mailbox store rather than on individual user mailboxes. Administrative Model The IT group is centralized in the Portland, Oregon office. This group is responsible for all network administration, including routing infrastructure, messaging, and network permissions. This group is also responsible for Exchange 2000 Server permissions and for maintaining Active Directory. Messaging Environment Fourth Coffee wants to implement a 40 megabyte (MB) storage limit for each employee. Company executives will not have a storage limit. Fourth Coffee wants to have the ability to control message flow between all office locations. The server hardware that is available for the deployment of Exchange 2000 Server is able to support up to 800 mailboxes on each physical server. A digital linear tape (DLT) tape library is attached to one server in each office. The DLT tape library performs backups on all servers in each office and is able to back up approximately 7 gigabytes (GB) per hour. Appendix C: Fourth Coffee Case Study 3 Network Infrastructure While out of the office, employees connect to the company network by using dial-up connections to a server running both Windows 2000 Server and Routing and Remote Access Service (RRAS). Each office has a 10 megabit per second (Mbps) Ethernet network for all servers and all client computers. All four of the company's other offices connect to the Portland, Oregon office by using 768 kilobit per second (Kbps) Frame Relay Circuits. All employees access the Internet by using a Microsoft ISA Server that is located in the Portland, Oregon office. The IT group has convinced the owners that Outlook 2000 client performance will be decreased if the users in each office must connect to mailbox servers in Portland. 4 Appendix C: Fourth Coffee Case Study Exchange 2000 Server Requirements and Goals Security Requirements Fourth Coffee wants to ensure that its servers running Exchange 2000 are not used to relay unsolicited commercial e-mail (UCE). They also want to protect employees from receiving UCE messages and e-mail from non-existent Internet domains. The Portland, Oregon office has a perimeter network that contains a server running Internet Information Services that provides Web content for business partners and customers. The perimeter network is configured to allow only Hypertext Transfer Protocol (HTTP) port 80 and Secure Sockets Layer (SSL) port 443 traffic into and out of the perimeter network. If it is necessary to do so in order to meet business requirements, additional ports can be opened. Availability Requirements Fourth Coffee wants to ensure that its servers are configured for optimal performance and availability. They do not believe that either clustering or load balancing is a requirement for their business. Design Goals To reduce the cost of remote connections for its employees, Fourth Coffee wants to explore the return on investment of using virtual private network (VPN) access instead of asynchronous RRAS connections. The Exchange 2000 Server design should use the available server hardware as efficiently as possible. Therefore, when possible, servers should be configured for multiple roles. For example, one server could perform both as a mailbox and as a public folder server. . justified. 2 Appendix C: Fourth Coffee Case Study IT Environment Overview Fourth Coffee currently uses an outdated version of Lotus cc:Mail.
