This chapter describes how to install the Network and Security Manager (NSM)
management system and configure it to provide for high availability. This installation
includes performing any prerequisite steps, running the management system installer
on a primary and secondary server, configuring both servers to failover in the event that
the primary server is unavailable, running the User Interface installer, and validating that
you have installed the management system successfully.

NSM with high availability requires two physical servers:
A primary server that runs on a server machine in active mode
A secondary server that runs on a different server machine in standby mode
If for any reason the primary server becomes unavailable, then the secondary server takes
over as the active management system.
