Creating Storage System Volumes and LUNs

After you determine how many LUNs you need for your SnapManager configuration and what data those LUNs will hold, use the information in this section to develop your SnapManager data configuration plan and prepare storage system volumes and LUNs for use with SnapManager. This entails calculating and recording the required sizes for the LUNs, which also determines the sizes of the volumes that contain the LUNs. Use the information you record in your SnapManager data configuration plan to create or modify the storage system volumes and LUNs on your storage system.

This section covers the following topics:

• Developing your SnapManager data configuration plan
• Calculating LUN size for Exchange databases
• Calculating single-instance sharing ratio for a database LUN
• Calculating deleted-item cache size for a database LUN
• Calculating LUN size for transaction logs and SnapInfo directory
• Calculating volume size
• Effect of new features on volume sizing
• Preparing storage system volumes and LUNs for SnapManager
