This brings up the question of what do you do if your disaster is SO bad
that natural gas distribution is disrupted.  Well my take on that is
that your area of the country will be in SO much trouble, that you being
out of business will make little difference.

You might considering Clustering to increase system availability: http://www.as400.ibm.com/ha/ha_clusttech.htm

What happens if you have a transformer blow out outside of your building, and it takes a day or so to get it working again?  I ask because this has happened at least once in 3 of the last 4 years here (the first ice fall here and the foot heaters go on).

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?
