[Tfug] Don't yell at your SAN!

[Bowie J. Poag]

...You'll hurt performance. Yell at the SAN administrator instead. :)

I wouldn't dare try to confirm this where I work, but it seems like a 
valid conclusion. Something tells me that the environment that they're 
doing the testing in is already close to the operating threshold for 
ambient noise, and yelling at a drive is just pushing it over the line 
momentarily. It could also be that a drive is noticing a temporary 
airflow restriction when the guy cups his hands over it, and is dropping 
RPM in response...although I've never heard of that happening in the wild.

I spent the better part of a week drilling down on a performance 
bottleneck on one of our NetApps a few weeks ago, so this makes me 
giggle a little.. It's the one thing I didn't have on the 
checklist---Are there people in the server room yelling at the drives? :)

Cheers,
Bowie


(PS..the bottleneck wasn't my fault, btw...so :P* pthbbbbt!)
