The Overview Snet I/O screen displays the traffic in and out of the ServerNet interconnects at the CPU level. Certain traffic is counted twice, so the chart is just a general idea of the traffic rate and distribution.
The 3D chart presents data transfers from all CPUs to all CPUs. On older ServerNet systems the chart appears more 3-dimensional than on newer systems. Newer systems seem to only display a 3-dimensional effect under very heavy load.
The chart presents the Read / Write Requests and the Read / Write Byte rates.
Below is a portion of the same screen from an older system showing the 3-dimensional affect.
