AirGroup Scalability Limits
Table 234 displays the total number of AirGroup servers (Apple TV, AirPrint printer) and users (iPad) supported
in individual controllers:

Table 234: AirGroup Server and User Limits in Controller
In a multi-controller deployment, there is a scaling limit of 2,000 AirGroup servers and 16,000 AirGroup users for all
controllers in a cluster. If you require more servers and users than the prescribed limit, configure multiple clusters,
so that each cluster is within the prescribed limit.
The ArubaOS scaling limits are based on the following metrics:
l Memory Utilization
l CPU Utilization
Memory Utilization
The memory utilization is affected by the number of AirGroup servers and users in an AirGroup cluster. In an
AirGroup cluster, the total number of AirGroup servers and users cannot exceed the limit defined by the top-
end controller. Based on the memory utilization, Table 234 summarizes the maximum number of AirGroup
servers and users for all supported controller platforms.
CPU Utilization
The CPU utilization is measured by the rate at which the controller receives mDNS packets. The rate of mDNS
packets in the cluster depends on the number of AirGroup servers, users, and number of applications installed
