From Omninerd: "Brendan Gregg from Sun's Fishworks team makes an interesting observation about inducing disk latency
when he tries yelling at active disks."As it turns out, you shouldn't yell at your disks, even if they're misbehaving and they've pissed you off. Yelling at them won't help as shown in the video on this blog. In fact, screaming at them induces latency and reduces performance. One theory: sound vibrations from excessive noise negatively impacts disk platter performance. This should be a wake-up call to system and data center cabinet designers: build systems to reduce noise (e.g., loud and annoying fans) and build cabinets to dampen/absorb subtle vibrations. Doing could "theoretically" improve overall JBOD performance. Remember, disks have feelings too.
