Multi-Server Deployment - Xerox Secure Access Unified ID System Installation Manual

Installation Overview

Multi-Server Deployment

An installation where all services are installed on the same server is referred to as a "local" install.
However, some installations may require more than one server to distribute the management load.
Installations where services are distributed over two or more servers is referred to as a "remote" install.
Whether you deploy a single or multiple server installation, the DRE and DCE services must always be
on the same server.
