Understanding storage system requirements

This topic describes the following information:

Storage system requirements

To be used with SnapManager, your storage system must meet the following requirements.

Storage system component	Requirements
Data ONTAP	See the SnapDrive software requirements described in the SnapDrive Installation and Administration Guide for your version of SnapDrive.
iSCSI or FCP protocols	The appropriate LUN access protocol software must be installed on the storage system that stores the Exchange databases. For more information, see the SnapDrive Installation and Administration Guide for your version of SnapDrive.
SnapManager licenses	If SnapManager is licensed per storage system, a SnapManager license is required on the storage system. Note With storage system SnapManager licensing, if you use SnapMirror in conjunction with SnapManager, SnapManager must be licensed on both the source and target storage systems.
SnapRestore license	For SnapManager restore operations to work properly, the SnapRestore® feature of SnapDrive must be licensed on the storage system that stores the Exchange databases. For more information, see the SnapDrive Installation and Administration Guide for your version of SnapDrive.
SnapMirror license	If you plan to use the SnapMirror software in conjunction with SnapManager, a SnapMirror license is required on both the source and target storage systems. For more information, see the SnapDrive Installation and Administration Guide for your version of SnapDrive.

About storage systems that have multiple IP addresses

If your storage system has multiple IP addresses, configure the SnapDrive preferred IP address. See the SnapDrive Installation and Administration Guide for your version of SnapDrive.

If you do not configure a SnapDrive preferred IP address for a storage system that has multiple IP addresses, SnapDrive times out when attempting to create Snapshot copies simultaneously for more than one LUN on a storage system.
