The Life Cycle of a SAN
The HAFM application enables you to proceed through the managed life cycle of
the SAN with confidence.
Figure 1: The Life Cycle of a SAN
The first stage of a SAN’s life cycle is to Plan the SAN. Use paper and pen or a
software application to plan the SAN.
The second stage of the life cycle is to Discover the SAN. The HAFM application
establishes contact with many SAN devices, gathers embedded information, and
then depicts it in the Physical Map, or topology. The application discovers the
devices attached to the SAN and presents an intuitive visual map of devices and
their connections.
The third stage of the life cycle is to Configure the SAN, during which you should
configure SAN devices and fabrics.
The final and longest stage of the life cycle is to Monitor the SAN. The
application generates events and messages about product and property status. The
user interface features an animated display of the data flow and error rates over
the entire topology. The application’s self-monitoring, event-logging, and event
notification features allow you to stay informed about the state of the SAN.
At any point, a discovered SAN can be used as a starting point to plan a new SAN,
completing the life cycle.
