Datasheet

Exchange servers with four cores per servers, you should have at least two cores ded-

icated for global catalogs.

If you’re planning to host Exchange servers for multiple domains at a single AD site, then

you must include domain controllers from each domain for which you host resources.

Exchange Server 2007 System Requirements

You must also understand the system requirements for Exchange Server 2007; that way you

can plan your server hardware accordingly. Table 1.2 lists these requirements.

Using Exchange Server 2007 on Member Servers or

Domain Controllers

You must also consider on what Windows 2003 server role you want to install Exchange

Server 2007: member servers or domain controllers. Even though Microsoft supports the

installation of Exchange Server 2007 on domain controllers, I strongly advise against it. This

is because you need to be a local administrator to manage an Exchange Server 2007 server,

and local administrators will automatically receive Admin permissions on all of your

domain controllers.

There might be circumstances, such as branch-office situations, in which you do not have

a choice, as hardware is spare or budget is limited. I’ve seen situations where a single piece of

hardware held everything: domain controller, Exchange server, file and print services. How-

ever, avoid that if possible.
