I have used Doubletake to fail-over my SQL machine
and it works very well. I have never had to truly failover, but in
testing on multiple occasions it had no hitches. I really like the
ability to do backups off of the mirrored machine. It's only drawback is
that fail-back requires downtime to re-sync, but that may not be as big of
an issue with imail.
Regards,
Steve
