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).

Subject: High Availability

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?
