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

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.


Damn, hadn't considered that one... anyone recomend any good websites
selling meteroid sheilding?

Weir-d must know one.
