Explanation

In this context, NAS refers to the Cisco NAC Appliance Server (Network Admission Control), not network-attached storage. A NAC Appliance Server's user capacity is primarily a function of CPU and session-processing resources, which are consumed by the number of posture checks per scan and the number of plug-ins evaluated per assessment. The total number of managed devices also drives concurrent session load. Raw network bandwidth, however, is rarely the bottleneck for a NAC server - it passes relatively little data per session - making it the least important factor among those listed.
