High Availability

[DanDaFourOOMan <danda400man@xxxxxxxxx>]

I am needing to consider high availability options for our new
AS/400s, which I am responsible for configuring.  A recent
thread discussed RAID vs. mirroring.  Another thread mentioned a
product named Mimix, which I've seen advertised.

The new AS/400s are replacing old ones and we have one in each
of our five plants spread across the U.S., one in Mexico, and
one in England.  Needless to say, I need to be able to manage
these systems and diagnose and solve problems from our corporate
office.  Management appears to be opening the wallet to ensure
HA.  Some critical considerations: Unplanned outages of 8 or
more hours would hurt us.  Greater than 24 hours and I'll be
passing out resumes.

Where can I go to read up on the issues I need to consider for
HA?

Any advice on which way to go on RAID vs. mirroring?

Any other advice?
