FIGURE 1.3 Exchange Server 2007 roles
In a smaller organization you will probably end up having a server that hosts
multiple roles, mainly the Mailbox, Client Access, and Hub Transport roles.
The larger the organization, the more dedicated those server roles will get.
Exchange Server 2007 Editions and Licenses
The next important area to consider when planning your Exchange server deployment is
which editions of Exchange Server 2007 you will use and what type of licenses you will
buy for your users. This topic is especially important, as it can save you money if you plan
thoroughly.
Exchange Server 2007 Editions
As in previous Exchange versions, there are two server editions available: Standard and Enter-
prise. Whereas the Standard Edition is targeted for small-to-medium companies, it also can be
used for specific server roles as well as in small branch offices. The Enterprise Edition supports
failover cluster and more storage groups and databases, and thus is targeted to large compa-
nies. Table 1.4 provides an overview of each edition’s offerings.
