Keerti Melkote presented the history of Aruba and told us they celebrated their 11 year birthday on February 14th! Aruba sees opportunity for innovation around client location awareness and utilizing software defined networking architectures in a campus environment. IPV6 will continue to be more and more important and will impact network designs in the future.
Aruba AirWave: Monitoring the Health of a Wi-Fi Network from Stephen Foskett on Vimeo.
AppRF in version 7.7 will provide information to AirWave (similar to Cisco's AVC) will show the top 3 destinations of client traffic, top trends for top 3 applications and uses NetFlow-like information.
Aruba Controllerless Wi-Fi from Stephen Foskett on Vimeo.
One of the access points at a remote site would have an https connection to AirWave for reporting on RF statistics. The number of possible users per controllerless group depends on vlan sizing. Aruba no longer recommend lots of access points in the branch managed by a controller in the data center and for the home offices, Aruba is still recommend having a controller at HQ managing the remote home users.
Aruba makes use of software managed AP purposing, instant APs, RAPs etc. The access point function is determined by the software that has been loaded onto the access point.
Ozer presented the evolution of the controller/controllerless architectures. There are many reasons why you would choose a controller based solution vs a controllerless solution.
Questions to ask your wireless vendor about their architecture options:
Can your controllers perform:
- Centralized encryption and policy enforcement?
- Local and centralized switching at the same time?
Can your controllerless APs:
- Self configure from the cloud
- Work without extra management software
Can i move from controllerless to controllers?
- Without going to the ceiling?
Can I mix and match architectures?
Scott Calzia (Product Manager of Aruba's Campus Controller product line) reviewed the features/functions of the 7200 series controller. It's the 3rd generation controller platform. There are 3 models of controllers: 7210, 7220, 7240. Each has four 1/10GB interfaces. The pair of dual media ports, can be used for interface connectivity, OOB or HA. Each has hot swappable load sharing redundant power supplies and field replaceable fan trays. There is an optional expansion slot *currently not in use*.
The highest end controller can support the following:
2000,000 firewall sessions
2048 APs, 32k devices 40GB
8 cores cpu, four cpus each.
SSD 8GB SD RAM 8GB EOS Flash memory
The controller hardware available now scales to support 4x the number of access points than it did previously.
The controller can support up to 40GB of encrypted throughput.
Balajee Krishnamurthy (Aruba TME) described AppRF as able to define policy decisions based upon applications detected on the wireless network. AppRF can identify applications based on ports and urls being used/accessed. deep packet inspection is possible and there are heuristics for lync, bittorrent, skype. AppRF can monitors the call setup and sync to differentiate Lync voice from Lync data (XML API). Lync voice/video over the air is prioritized, reporting in the Firewall dashboard doesn't have the differentiation to show the different data streams in Lync.
David Munro and Neil Kulkarni covered the Aruba Instant / controllerless solution.
The activate as a service is free for Instant AP deployments via activate.arubanetworks.com. If you have a virtual controller at remote location, additional instant aps discover virtual controller and download image and config from airwave management mode at the data center
