Doing an intensive 3-day NetApp & VMware healthcheck for a customer, and I found the “Ghost in the Machine”.
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?
