Sane SAN

 
 

SANE SAN
The Random Acronym Seminar (or RAS for short...)
James Morle, Scale Abilities, Ltd.

Introduction
This paper talks about storage within SANs. It is easier than ever to implement a badly laid out SAN, with the levels of abstraction and data sharing made possible through this technology. We will look at ways this can be simplified though careful planning, and discover why its a good idea to lie to your boss. Before that, though, it's worthwhile taking a journey into the past to find out why all this stuff exists, and why there are so many acronyms in the storage industry.
 

RAC synchro reader - beta

I had a problem (way back in April 2007) on a 4 node RAC. I spread out the alert logs from the 4 instances in front of me and tried to see a timing correlation across the nodes. So, "X" occured at 12:54:13 on NodeA, what happened at NodeB; so I search (with my editor) for a "close" timestamp in the other alert file... this was tedious!! So I wrote a quick program to try and do this automtically. A text browse of the alert file(s) with an automtic implict search of the timestamps.
The program is freely available (no guarantee, your milage may vary, professional driver on a closed course, do not wash, mangle or wring, not valid about 5600ft, etc and so forth) here at the oaktable site.
