Aruba OS

The Aruba OS runs on the Mobility Controllers. As additional components RFProtect + WIP and a Policy Enforcement Firewall are available.

Access management

Unknown devices, that cannot authenticate to the network, can be given temporary access via Amigpod. It offers a self-service guest-registration web portal giving a visitor credentials to connect to the network. Via the software authorized (non-IT) staff can then allow this visitor to get access to the network or only to internet or parts of the LAN.

Network management

AirWave networkmanager is a generic network-management tool to manage switches, access-points and end-users. The software is also capable to follow users: where they are (mapping), their data-usage, RF-management etc.

Other software

Aruba offers other applications such as a outdoor RF planner and mesh-config for configuration of the mesh routers.

Acquisitions

On 10 May 2010, Aruba Networks confirmed it would acquire wireless mesh startup Azalea Networks. for $27 million in stock and up to $13.5 million in cash over the next two years. The acquisition will give Aruba another avenue for channel partners deploying advanced wireless mesh networks.
