The Multiport Monitor (as it's called now; it's the Multi-Port Collector in your diagram) is a rack device which is purchased through CA and delivered by our vendor partner. Consider this a black box device just like any other network device.
At a minimum, you'll need to setup a Windows server to run ADA Master Console (ADA MC). To utilize Single Signon (SSO), you will also need to purchase CA Performance Center or CA NetQoS Performance Center. Please speak with your CA Account Manager and/or Sales Rep.
