    We use DoubleTake software from NSI for software based failover/high availability. This is not clustering as only one server is active, the other is passive until a failover is initiated. We’ve had to use it several times and it works like a charm.

    You cannot really compare hardware clustering with something like WanSync, DoubleTake etc. They do something very similar but are worlds apart in terms of cost and hardware requirement.

    I am also of the opinion that many people who think they need clustering actually do not. I have deployed Exchange in to sites where the cost of downtime is measures in 1000s per hour, but they didn’t use clustering because other solutions were most cost effective when you take in to account the additional hardware outlay, training for the admins on how to manage the cluster etc.
