Because it requires a minimal hardware investment and minimal management overhead, the
Standard Edition confi guration is ideal for small and medium-size businesses as well as for
branch offi ces. It is intended for deployments with fewer than 5,000 users either in total or
at a particular location where high availability is not a requirement. The Standard Edition
provides full functionality for small organizations.
Enterprise Edition
The Enterprise Edition of OCS 2007 separates the server functionality from data storage to
achieve higher capacity and availability. An Enterprise Edition pool typically consists of two
or more Front-End Servers, each fronted by a hardware load balancer and connected to a
backend database. (If needed, it is also possible to deploy a single Front-End Server without a
load balancer.) Optionally, certain conferencing components can be deployed on separate
computers for higher capacity and availability. The Enterprise Edition is appropriate for
medium, large, and very large organizations.
Enterprise Edition: Consolidated Confi guration is a pool confi guration in which all the
server components are colocated on the pool??™s Front-End Servers (the only exception is the
placement of the backend database that must reside on a separate dedicated computer).
Consolidated Confi guration provides scalability and high availability while still being relatively
easy to plan, deploy, and manage.
Enterprise Edition: Expanded Confi guration, on the other hand, offers maximum capacity,
performance, and availability for large organizations.
