Re: Duplicate clustername value sets in config-subsititions file
I used to think that server farm is from management point of view (start/stop, deploy, monitor, etc.), and server cluster is from runtime point of view (fail-over, load-balancing, etc.). But after a little search, it seems that many people regard them as the same thing. Some people also has an interesting distinguishing between them. e.g, [1] classifies clusters into server farm and server pack. A farm shares the same applications and services but do not share the same repository of data, while a pack shares the data too. -Jack [1] http://www.certmag.com/read.php?in=1477 On Fri, Jul 10, 2009 at 10:28 AM, Rex Wang rwo...@gmail.com wrote: Thanks!

A cluster is a type of farm. I see a farm as a set of independent instances. I see a cluster as a set of collaborating instances. You can deploy a non clustered application to a farm whereby you do not have resilience in case of service failure. And you can deploy a clustered application to a farm to increase service resiliency if necessary.

Re: Duplicate clustername value sets in config-subsititions file
Rex, thanks for the patch. The solution is fine with me. If there is no objection or question regarding the change, I'll update the doc(1) when the patch is applied.
