The recommended maximum number of users per Archiving and CDR Server is 65,000,
allowing each server to support six front-end servers. For environments where you do not
have to ensure compliancy, this may be suitable, but if you are running in Critical Mode, this
could result in the loss of six front-end servers, resulting in a very high load on the remaining
servers and the possible loss of service to some users.
Your topology should take into account your compliancy requirements along with the
service level you want to offer to your users. The Archiving and CDR Server should run on
dedicated servers and use a dedicated database server to that ensure you are getting the best
performance.
Because organizations have different compliancy requirements and service levels, it is not
possible to provide a one-size-fi ts-all solution for archiving. Therefore, you should use this
information as a guideline for designing your OCS solution. Archiving should not be an
afterthought; you should consider it throughout the design stage.
Configuring Archiving ??? Chapter 7 231
Installing the Archiving Server
This section covers installation, activation, and confi guration of the archiving server. Each
process is distinct and is sometimes performed by different people in an organization. In this
section, we will discuss installing the Archiving and CDR Server onto a dedicated server in
an existing enterprise pool, using a SQL server on a dedicated server.
Installation
You need to install the Archiving and CDR Server on a Windows 2003 SP1 or later server
which is a member of the same domain as the front-end server.
