How to License the Storage Area Network (SAN) Option

To successfully license Arcserve Backup Storage Area Network (SAN) Option, you must fulfill the following installation requirements:

• You must install and license the option to perform backup operations to libraries that are shared on a SAN.
• You must install the option on the Arcserve Backup Primary server.
• You must issue all licenses on the primary server.
• Ensure that you have a sufficient number of Storage Area Network (SAN) Option licenses to support your environment.
• The Central Management Option is a prerequisite component for the Storage Area Network (SAN) Option.
• The Storage Area Network (SAN) Option is a count-based license. You must issue one license for all Arcserve servers that share a library with another Arcserve server.

Examples: How to License the Storage Area Network (SAN) Option

The following examples describe how count-based licensing works with the Storage Area Network (SAN) Option:

• Your environment consists of a primary server and three member servers. The primary server and the three member servers share a multiple drive library on a SAN. This configuration requires you to issue four Storage Area Network Option (SAN) licenses issued on the primary server. All servers in the Arcserve domain are sharing a library.
• Your environment consists of a primary server and three member servers. Two member servers share a multiple drive library and the third member server is configured with a locally attached, multiple drive library. This configuration requires you to issue four Tape Library Option licenses and three Storage Area Network (SAN) Option licenses on the primary server. All servers in the Arcserve domain have access to a multiple drive library; however, three Arcserve servers are sharing a library.
