For those of you not acquainted with the terms it is probably an irrelevent question but out of interest POC = proof of concept and HA = high availability!

For those of you that do know, I need to do a presentation in which the above subject is quite high on the agenda. The other bits - designing HA systems and comparing 2 different offerings (HP ServiceGuard and Veritas HA Clusters) I am quite happy with. But I am unclear on providing POCs in this environment. In all the work I have done it has been, by definition, Mission Critical. How do you provide a POC that may or may not suit the business when the application is vital to the business? I mean - if the POC doesn't work don't we loose business? I know we can run in a test environment but that is not realy a POC is it? Hmmmm.

I am of course investigating other sites and asking all the technologists I can think of but the Mudcat has been a great source of inspiration and ideas - I am sure it won't let me down now:-)
