SDN Controller Challenges: Transcript

The Story T hus Far SDN centralize the networks control plane The controller is effectively the brain of the network Controller determines what to do and tell switches how to do it The Story Thus Far. If the controller does not include an autotune algorithm or if the autotune algorithm does not provide adequate control for the particular application then the unit must be tuned using trial and error The following is a tuning procedure for the OMEG 1 Standard feedback controller plus RVS Figure 22 Drive circuit board with vibration sensors Rotational Vibration Safeguard RVS Rotational Vibration Safeguard RVS Seeing the future Selected HGST hard drives now have an advanced Rotational Vibration S Advait Dixit, .
