High availability is a redundancy operation that automatically switches to a standby server if the primary system fails or is temporarily shut down for maintenance. High-availability is an important function because it provides fault-tolerance to mission-critical systems that rely on consistent availability and performance. Unlike a single-server system, a high availability setup maintains your data and service availability, reducing or eliminating system downtime because of software or hardware failure.
BMC ProactiveNet in high-availability mode consists of two servers with identical configurations. The first server is referred to as the primary node. The second server is referred to as the standby node. The two nodes share a logical IP address and cluster name. Both servers have access to a shared storage disk.
The primary node BMC ProactiveNet Server installation should use a logical IP/host name and be installed on the shared storage disk. When the primary node is down the secondary node picks up the installation from the shared storage disk.
