When designing a Cascade deployment which of the following is important to consider about sizing?

Cascade is sized based upon the number of sources that will be sending NetFlow to a Gateway, and the number of Gateway's sending data to a Profiler. Each Gateway is sized to handle a certain number of sources, and each Profiler a certain number of Sensors and Gateways.

Cascade is sized by the packet volume across the environment. Each Sensor and Gateway component can handle a certain packet rate.

The primary measures are flow-rate and topology. Flow-rate drives the size of the solution; topology can determine the placement of Sensors. As a secondary sizing method we can use host count and rule-of-thumb host/flows ratio to estimate the flow-rate.

Cascade is sized purely based upon the number of Servers being monitored in the environment.
