Doing an intensive 3-day NetApp & VMware healthcheck for a customer, and I found the “Ghost in the Machine”.
How much difference does a solid state hard drive or disk array make for laptop/desktop users?
Your NetApp DFM (OnCommand Core) Performance Advisor is lying to you… It doesn’t want to. And it doesn’t mean to. But it is. This was an issue that a customer came to me with yesterday.
If you asked your NetApp or DFM, “Hey dude, what’s my CPU utilization?” DFM may reply back, “Ohh man, you’re screwed, it’s 95%!” You instantly crap yourself since you just paid big money for all this stuff, which should last for years. Don’t worry, more than likely you’re good. Let’s take a look at why is it lying to you?
