The reference topology for a large organization with multiple data centers support is for any size of organization with more than one central site. The exact topology in the following diagram is for an organization of 50,000 users, with 20,000 users at Central Site A, 20,000 at Central Site B. and a total of 10,000 at Central Site C and branch sites. The type of topology shown in this diagram can accommodate organizations with any number of users.

In addition to the high availability provided by pools of Front End Servers, this topology adds disaster recovery support. The Front End pools at Central Sites A and B are paired together. If one of these pools goes down, the administrator can shift the services for the affected users to the paired pool at the unaffected site.

This topology is shown in multiple diagrams, with an overview first followed by detailed views of the central sites.
