We have production ha-pair production servers. When we are investigating on a 3rd party software, sa's are talking about two sun servers clustered together. What is 'clustered' and how is it different from being an ha-pair?

Thanks in advance,
Shine.
 
it's more or less the same; Sun says a cluster is just the set of machines bound together for a specific function. There are HA solutions (was it Sun Cluster 2.x?) with one active node and n "spare" / hot stanby nodes, and Solutions, like VeritasCluster&Oracle9iRAC, where you have n Nodes serving parallel the same application.

In the 3rd party documentation context I think it just means the set of nodes...
