sory if this topic dont related with this mailing :)

Depends on what type of clustering you are talking about. Usually people refer to "HA" (high availability) clustering. It is usually accomplished by having two boxes, one is a stanby,

It officially becomes an "HA Cluster" when you have an automated
status monitoring system that initiates a failover process from
a failed prinary server to the waiting backup server.

Sometimes people talk about a distributed processing cluster,
I don't know much about these, but it basically means that you
have a bunch of machines using high speed networking and they
all work together to solve a problem.  A very "loose" processing
cluster is something kind of like "setiathome", places like
high energy physics labs or large structure mechanical engineering
simulations use distributed processing clusters.
