Introduction

CA ARCserve Replication and High Availability (CA ARCserve RHA) is a solution based on asynchronous real-time replication and automated application switchover and switchback to provide cost-effective business continuity for Microsoft Exchange Server and other application servers on both 32-bit and 64-bit Windows servers.

CA ARCserve RHA lets you replicate data to a local or remote server, making it possible to recover that data due to server crash or site disaster. You may switch your users to the replica server manually, or automatically, if you licensed High Availability. This Guide presents both Replication and High Availability concepts and procedures.

The procedures covered in this Guide should be followed as is. Customize the steps only if:

• You are familiar with CA ARCserve RHA and fully understand the potential impact of any changes you make.
• You have fully tested the steps in a lab environment before implementing in a production environment.

Support for New Microsoft Exchange Server 2010 Features

This version of CA ARCserve RHA supports the following for Microsoft Exchange Server 2010:

• Auto-discovery
• Replication
• High Availability
• Data Rewind
• Assured Recovery

Exchange Server 2010 introduces an important change to the database hierarchy. The concept of a storage group has been removed, and public folder databases and database management have been moved to the organization level. In Exchange Server 2010, database protection is provided by Database Availability Groups (DAG). Database Availability Groups are not supported in Replication or HA scenarios. When a Master or Replica is part of a DAG, the software will display a warning.

Note: CDP Repository is no longer supported.

Important! Due to this hierarchy change, you cannot create a database with the same name on both the Master and Replica servers, even if the database is dismounted. To overcome this limitation, functionality has been built into the software that allows it to temporarily rename the database for switchover purposes.

In CA ARCserve RHA, replication and high availability protection has been moved from the storage group level to the mailbox store level.

Users now connect to their mailbox through a server that fills the Client Access Server (CAS) role, while Exchange Server 2007 allowed users to connect directly to their mailbox server. In CA ARCserve RHA scenarios, the CAS server must be available in order to fulfill a client access request. The method you used to deploy CAS determines how the software protects the environment.

If the Master server also fulfills the CAS role, the Replica must do the same. You can decide at scenario creation time whether to confirm CAS on the Replica. If the Master server holds only the Mailbox role, CAS must be confirmed on the Replica at scenario creation time.
