About this guide This document is a HP StorageWorks Storage Mirroring application note. An application note provides guidelines on the use of Storage Mirroring in a specific environment. This document contains: Document Overview: Explains what an application note contains, how it should be used, what you need to know before trying to use the application note, and where you can go for more information.
Related documentation Before you begin to configure your solution, make sure that you have complete documentation for your operating system, application, and Storage Mirroring. This application note does not provide step-by-step instructions for using standard operating system, application, and Storage Mirroring functionality.
CAUTION: Indicates that failure to follow directions could result in damage to equipment or data. IMPORTANT: Provides clarifying information or specific instructions. NOTE: Provides additional information. TIP: Provides helpful hints and shortcuts. HP technical support For worldwide technical support information, see the HP support website: http://www.hp.

1 Solution Overview Microsoft System Center Virtual Machine Manager (VMM) is a virtual management solution optimized for Windows® Server® 2008, Microsoft Virtual Server, and VMware infrastructures. VMM enables consolidation of physical servers onto virtual machine infrastructure. Storage Mirroring provides real-time enterprise data protection and replication. Storage Mirroring can be used to provide high availability for your Virtual Machine Manager server.
Enabling compression By enabling compression, you can reduce the amount of bandwidth needed to transmit Storage Mirroring data. When compression is enabled, the data is compressed before it is transmitted from the source. When the target receives the compressed data, it uncompresses it and then writes it to disk. On a default Storage Mirroring connection, compression is disabled.
2 Sample Implementation This section describes an example of how to configure Storage Mirroring and Virtual Machine Manager. Use these procedures as a guideline for creating your own implementation. Because no two environments or configurations are exactly the same, you will probably need to implement additional or different steps than what is documented here in order to make the solution work in your environment.
Configure and begin mirroring and replication 1. 2. 3. 4. 5. 6. Select Start, Programs, Storage Mirroring, Full-Server Failover Manager. Enter your source and target servers. You can click Browse when selecting either server to locate it by drilling down through your network. After you have specified a server name, enter login credentials when prompted. Once the server is selected and logged in, the Properties tab at the bottom of Full-Server Failover Manager updates to display the server’s properties.
Restore your data After your target has failed over and becomes your source, you can stay with that configuration long term. However, you can go back to using the original hardware after you have failed over. Use the following process to failback to your original (or other) hardware. For details, see the HP StorageWorks Storage Mirroring user's guide . 1. Because your new source is on the network, you must make sure your original source is unique on the network to avoid name and IP address conflicts.
