A typical solaris cluster configuration comprises of the following components:
Hardware components:
- Servers with local storage
- Share storage
- Cluster interconnects
- Public network interfaces
- Administrative workstation
Software components:
- Solaris running on each node
- Solaris cluster software dunning
- Data services.
The server in a cluster use private interconnects to communicate with each other. These interconnects are responsible for carrying the cluster information. The information carried is also known as the heartbeat. This heartbeat lets the servers in the cluster monitor the health of other servers hence ensuring that every other server is alive in the cluster. In case of a server failure the heartbeat of that server disappears and the server is not considered to be the part of the cluster. The term used to isolate the failed server is known as fail-over. The clusters are characterised by the high rate of availability.
