Hi Chaps,
This is certainly a very interesting discussion.
I've managed to convince management that Guaranteed 100% uptime really
isn't a possibility, and I've explained that the considerable costs
associated with any clustering/cloning solution would make the marginal
increase in reliability not worth the investment. I am instead going to
ensure that spare hardware is on-site in case of an incident such as
last week's. So they're happy, for the moment anyway.... 
But the discussion has piqued my interest. Regarding the duplication
software: The marketing blurb sounds very impressive, but I would like
to hear if anyone that has actually used any of these on a system that
did actually fail. How did it perform compared to a similar scenario
involving a cluster? Personally, if I was to implement anything like
this in the future, I would prefer to use a native MS (clustering) -
rather than third party solution (duplication). It would be interesting
to hear first hand accounts.
