If you're after high availability this is poor design. You've introduced a single point of failure with your high-capacity UPS. Remember that the goal of HA clustering is to eliminate as many single points of failure as possible. It would be preferable to have at least one UPS per server that you have, much better to have more than one... -- dido We pledge allegiance to the Penguin, and to the software for which it stands.
