    Hai Friends,

    What is the maximum number of AP that can be added in a cluster with out a controller.
    Using APs like 305,505 etc..
    (Making these as the virtual controller)

    Tested up to 128

    You can refer to the post

    Cluster Design
    By default, all Aruba IAPs on a Layer 2 domain form a cluster. No hard limit exists on the number of APs or clients that you can support on a single cluster. However, the maximum tested IAP cluster size is 128 IAPs in a cluster.
    Guidelines for cluster and mobility design include the following guidelines:

    • Aruba recommends that you use the validated cluster size of 128 APs and 2048 clients per cluster for your cluster design.
    • To allow for some future growth, design a cluster at 80 to 90 % (about 110 APs) of the validated capacity.

    Although the validated cluster size limit applies to a cluster, you can expand a deployment to more than 128 APs by deploying multiple clusters that have Layer 3 mobility enabled between them.

    • If a deployment within a contiguous RF domain requires more than 110 APs, divide the deployment into multiple clusters and enable Layer 3 mobility between them.
    • Layer 3 roaming has little to no impact on performance if you enable the Home Agent Load Balancing feature that is part of the Aruba Instant architecture. If you enable this feature, the VC assigns the home AP for roamed clients by using a round robin policy. With this policy, the load for the APs acting as home agents for roamed clients is uniformly distributed across all the IAPs in the cluster.

    NOTE: Aruba recommends that you enable the Home Agent Load Balancing feature in deployments in which you expect a high volume of Layer 3 roaming between clusters.

    You can also check with your local Aruba SE to learn more about AOS 10 with Central which removes this 128 AP limitation per cluster.
