The first step in creating a topology is to understand the goals of your organization. Similar to Chapter 2, Analyzing Your Communications Suite Requirements, Siroe’s messaging goals can be categorized into business objectives, technical, and financial constraints.
The finance, marketing, legal, IT, and engineering groups are located in New York. The creative groups are located in Los Angeles and in San Diego. The technical support groups are located in Chicago and Minneapolis. Most messages are sent between Chicago, Los Angeles, and New York.
Employees at the Siroe Corporation rely on email as their primary method of communication. On average, employees send approximately 15 messages per day with attachments in the form of spreadsheets, presentations, or animation.
The deployment planners determined that Message Server hosts would be set up in Chicago, Los Angeles, and in New York. Since the volume of email traffic in San Diego and in Minneapolis is relatively light, these satellite offices will only have mail clients connecting to servers that are located in Chicago and in Los Angeles.
Because of budgetary restrictions, Siroe will be using the existing infrastructure and hardware that is already in place, moving servers to locations where there is critical need. 24x7 support will be available only in the New York, Chicago, and Los Angeles offices. All offices will be connected by T3 lines to the Internet.
