Toto, the following is why ignoring this Ron "character" is good
advice:


The only way to ensure that the data held at that instant in the
cache(could
be none) is not lost is to have some sort of battery support. A UPS is
often sufficient. Losing some data in the cache does NOT mean that you
have
lost all integrity...just a small amout of the most recent data.

Without meaning to take sides, would someone mind explaining a situation
whereby a general UPS would not be sufficient to protect data integrity
in the event of a power failure?

A micro Weir meteroid hits the UPS wire because its so far away from the
RAID controller maybe.
