Kevin Loney suggest to us using Quest Software's Shareplex and special =
EMC hardware/software for HA.
This is used by one of the U.S. stock exchanges (I can't remember which =
one right now). The boxes
are located on other ends of DS3 lines, hundreds of miles away from each =
other. It's expensive,
but will survive demolition of one of the sites. Literally.

I am trying to understand the possible pieces going into providing =
