Related , but totally unreleated to the thread, just some food for thought :-)
The interesting thing about clustering, is more: What are you trying to achieve? Availability, ok, why? what are your business requirements? Is it: a) the organisation *really* can't do without email for a day. b) I can't do without my diary for a day because it causes embarrassment for me not knowing what meetings I am at and who my contacts are c) something else I worked for a company that needed b). We looked at SANS and clusters and alike, priced it up and picked ourselves off the floor. Scary price but , could still justify it. We looked at other threats to the availability of exchange that a cluster may not be able to eliminate, virii, power or infrastructure failure (hmmm NY blackout springs to mind) and look at how to mitigate them. We then looked at b) again and said "how else can we get this outcome" We then came up with the idea of an Pocket PC for every person that needed their contacts and calendar. At the end of the day for every risk we identified (apart for fire or building collapse) was covered by a Pocket PC at a far cheaper price that all the high availability gear we were looking at. Nothing wrong with HA approach, but for what we wanted to achieve, it was not the only answer. cheers Dean >>> [EMAIL PROTECTED] 3/10/2003 3:23:55 p.m. >>> Far from an endorsement (from me that is), but at TechEd there's was a lot of talk from Microsoft and HP about them running E2k3 clusters in house.

Does anyone on the list have field or lab experience with Windows Server 2003 and Exchange 2003 running Active/Active clustering. Are the noted issues inherent in the Exchange 2000 architecture and Active/Active clustering still a concern with the new technology?
