Chapter 1 Concepts : Cluster Support Limitations

Cluster Support Limitations
Some cluster vendors, such as Veritas allow the use of parallel groups. A parallel group can run concurrently on multiple systems in the cluster at a time. A parallel service group is more complex than a failover group. It requires an application that can safely be started on more than one system at a time with no threat of data corruption, or that the data being accessed is local to each server.
Cluster vendors also provide load balanced cluster groups. A load balanced cluster solution helps to implement an enterprise-wide scalable solution for incoming TCP/IP traffic. This solution is commonly used for web server applications.
Applications that are deployed to a load balanced cluster run separate copies of the applications on each host machine. Network load balancing distributes incoming client requests across the machines in the cluster.
