HP OpenView Storage Mirroring High Availability for Exchange Server 2000/2003 Application Notes (May 2005, T2558-88020)

Storage Mirroring High availability for Exchange Server 2000/2003 application notes 3
Introduction
Microsoft Exchange Server is a messaging and collaboration server for the most demanding business
needs. Its scalability, performance, and enhanced security make Exchange an ideal messaging
foundation for enterprise networks. Storage Mirroring provides real-time enterprise data protection and
replication. Storage Mirroring can be used to provide high availability for your Exchange server.
This document describes the steps necessary to configure Storage Mirroring to provide high availability for
Windows servers running Microsoft Exchange Server version 2000 or 2003. These procedures allow a
secondary server to assume the identity and role of a failed Exchange server while maintaining the
availability of Exchange services with minimal disruption or data loss. That means that users will have
access to the same mailboxes and public folders on a uniquely-named target server that existed on the
source server prior to a failure.
In addition to the Exchange Information Stores (mailboxes and public folders), there are many important
aspects of an Exchange server configuration that are required for Exchange functionality following the loss
of a production Exchange Server. It is important to be aware of the overall production Exchange server
configuration and to configure the target server identically. Some configuration aspects fall outside the
scope of this document such as the configuration of any Exchange Connectors, Built-In Instant Messaging,
Newsgroups, Bridgehead Servers, and so on. These issues need to be addressed exclusively by the
Exchange administrator.
To complete these instructions, you will install Microsoft Exchange Server and Storage Mirroring, then
configure Storage Mirroring for replication and failover. Due to the complexities of these applications, this
document is intended for network administrators with experience installing, configuring, and maintaining
network applications, including Storage Mirroring and Microsoft Exchange Server. This document is not
intended for Exchange running on Microsoft Cluster Service. It is for configurations with Exchange running
on member servers.
