[Leica] announcing the "imagestore" list

[scheng at aotera.org (Spencer Cheng)]

Mark,

It's more like plug and pray when something doesn't work. It may work  
when you first plug your RAID box in but when the RAID box start  
misbehaving and you have a year or 2 of your work on it, what do you  
do? Pray. :) B&H ain't going to help you then. :(

There are a lot of subtleties and trade-offs in how your image storage  
system is built which can make your like easy or hell. With 1TB disks  
in RAID-5 configurations, it is possible that a single disk failure  
will become a permanent failure (due to the amount of time it takes to  
rebuild the array and the probabilities of a soft fault occurring in  
one of the remaining disks).

In large disks, the number of molecules that is used to hold a bit  
(value = 0 or 1) is amazingly small. And correspondingly, the number  
of soft faults is amazingly large.

Regards,
Spencer
