Some of the limitations of Win 2K clustering should be being overcome in Win 2003. Check out http://www.microsoft.com/technet/treeview/default.asp?url=/technet/prodtechnol/windowsserver2003/technologies/clustering/default.asp for details. They seem to have taken a leaf out of Veritas's book and eliminated the Quorum drive, making N plus I (how do I put in a plus char in this utility - it seems to get eaten?) clusters possible which, let's face it, is where clustering starts getting interesting - all this 2-node active/passive stuff is pretty damn feeble.

We are currently evaluating Veritas's Clustering software vs. MSCS (the current 2K version) as there is obviously a big price incentive (VCS runs with std ed. Win & SQL - add up the licencing difference per processor for 3 or 4 duals or quads and it starts becoming serious money) but we're still too early in the process to give any firm opinions either way.

Anybody out there have experience running both?
