Well, the only issue that i'm aware is that the Exchange box being protected
can't go under a lot of processing/disk stress or else the secondary box will
stand in. The only way to prevent this is to put a serial cable connecting both
boxes so Brightstor can check if the other box is alive. No possible on WAN,
though.
I never had lost mail. I have a filtering server before the Exchange box, so
when the exchange box crashes, all mail is queued there until it comes back,
that is, for a short while.

Any known issues? How about lost mail?

I'm very familiar with CA's BrightStor High Availability Manager. It's
basically a service that monitors changes at file-system level and keeps a
remote disk with the same database that your Exchange has while it's online.
When your Exchange box crashes, it executes a series of tests to confirm wether
it's a network failure or if the "protected" Exchange box is indeed dead. Then,
the "Secondary" machine will set the dead Exchange's IP addresses and names on
itself and start the exchange services.
Once the Dead exchange box is brought back up, you can "reinstate" at some time
and all modified data will be copied back to the crashed machine and the
Secondary box will stand out.
In a matter of 30 seconds you're up and running. Also works with pretty much
any other Messaging, database and web servers available for Windows.

Anyone familiar with any of the Exchange failover/replication products
such as XOsoft WANSyncHA? Anyone care to comment on these approaches to
failover.
Thanks
