It was your rather odd usage of "affecting" that caused my confusion, made me think IOPS was some new internet acronym and something which could be affected as one would affect continental to sound cultured. I would have gotten the general gist had you said "causing IOPS" or if I knew Thumpers or maybe if you had used the full names of Cantrill and Gregg but I am not sure if I would have made that connection. Thanks for the clarification and the absolutely bizarre and quite interesting construction, I enjoyed this a great deal.

Edit: I clearly just got derailed by my initial confusion, there was nothing weird about your usage.

All good, I thought your point was fair either way, considering my original point of being clear about a link. Plus a chance for storytelling. =)

I don't understand what you find odd about "affecting IOPS."

If someone does something that has an impact on IOPS, then it's sensible to say they (or what they're doing) are "affecting IOPS."

Screaming at the JBOD wasn't "causing" IOPS, so using that phrase would've been more confusing.
