Energy consumption by multiple UPS's versus a single model.
Energy consumption by a 14 year old UPS versus a newer one.
Maintenance cost of a 14 year old UPS versus a warranty.
Parts availability of a 14 year old UPS.
One UPS might be easier to configure in and wire in to the generator that 
powers the whole building.  (A data center without air conditioning 
doesn't run forever.)
The other equipment is just as valuable as your iSeries.  For example, how 
many people can access your iSeries if it's running fine on a generator, 
but the router/switch isn't?  All eggs in one basket makes for a more 
reliable basket than several small baskets made out of wet tissue paper.
You spread out the cost of the generator to the whole data center versus 
making the appearance of the cost of the iSeries higher.

RE: UPS & Tape Drive






Understood.  We have a 10kVa unit dedicated to just our 820.  Been trouble
free for 14 years.  Just have needed to replace the battery sets every few
years.  Our phone system also has it's own UPS and then we have a number 
of
small APC units running servers and the like.

There has been talk that we should get one UPS to run the whole data 
center
but I kind of like having a 10kVa UPS dedicated to the AS/400.  Looking 
for
arguments for or against scrapping our 10kVa unit and getting the AS/400
connected to a UPS that would run a whole data center.

We have much more than the 820 on it and just under 1 hr run time.  We 
still
have room to add either UPS or Batteries too.

Sounds like a nice UPS. How many hours can an 820 run on a 16kva UPS?
