Single Node Support
Aruba Central (on-premises) is a deployment of Aruba Central in your datacenter. Aruba now supports single node deployment for users with a deployment size of any of the following:
- 1000 APs where APs can be either Instant APs, Campus APs, or APs along with the controllers that manage APs; or a mix of any of these devices.
- 500 switches where switches can be AOS-S switches or CX switches or a mix of the two.
- In a mixed mode of switches and APs, up to 800 APs and 200 switches are supported.
The supported devices include switches, controllers, Instant APs, and Campus APsCampus APs are used in private networks where APs connect over private links (LAN, WLAN, WAN or MPLS) and terminate directly on controllers. Campus APs are deployed as part of the indoor campus solution in enterprise office buildings, warehouses, hospitals, universities, and so on.. It also supports backing up and restoring system data from a single node deployment to three node deployment and above.

- Live Events
- APIApplication Programming Interface. Refers to a set of functions, procedures, protocols, and tools that enable users to build application software. Streaming
- Live Packet Capture
- AI Insights
- API Gateway
- RAPIDSRogue Access Point identification and Detection System. An AMP module that is designed to identify and locate wireless threats by making use of all of the information available from your existing infrastructure.
- UCCUnified Communications and Collaboration. UCC is a term used to describe the integration of various communications methods with collaboration tools such as virtual whiteboards, real-time audio and video conferencing, and enhanced call control capabilities.

Three, Five, and Seven Node Support in Aruba Central (on-premises) Deployment
A 3-node, 5-node, and 7-node support a minimum of 8000, 16000, and 25000 devices respectively. The supported devices include switches, controllers, Instant APs, and Campus APs.
On a 3-node deployment, High Availability (HA) is supported only on controller-based AP deployments.
You can check maximum number of supported devices of the Aruba Central (on-premises) setup in the Account Home > Global Settings > Subscription Assignment page.
If the device limit is exceeded, the device added to the system is displayed as Unsubscribed in the Account Home > Global Settings > Device Inventory page.
Three Node Support
Aruba now supports 3-node deployment for users with a deployment size of any of the following:
- 8000 APs, where APs can be either Instant APs, Campus APs, or APs along with the controllers that manage APs; or a mix of any of these devices.
- 3000 AOS-Switches can be deployed in switch only deployment.
- In a mixed mode of switches and APs, up to 6000 APs (IAPs or Campus APs) and 2000 switches (AOS-Switch or AOS-CX) are supported.
Five Node Support
Aruba now supports 5-node deployment for users with a deployment size of any of the following:
- 16,000 Campus APs along with the controllers that manage APs can be deployed.
- In a mixed mode of switches and APs, up to 10,000 Campus APs and 4000 (AOS-Switch or AOS-CX) switches are supported.
IAP and AOS-CX only scale is yet to be ascertained and will be documented in future release.
Seven Node Support
Aruba now supports 7-node deployment for users with a deployment size of any of the following:
- 25,000 Campus APs along with the controllers that manage APs can be deployed.
- 10,000 AOS-Switches can be deployed in switch only deployment.
- In a mixed mode of switches and APs, up to 16,000 APs (IAP or Campus APs) and 7000 AOS-Switches are supported.
Limitations
- AI Insights is not supported on single-node and 3-node clusters.
- On a 3-node deployment, High Availability has known issues for deployments with only IAPs, only switches, or in mixed-mode (CAP/IAP with switches) when the load is near high.
