Todd, You can check my other thread, bit my controllers have 2 10-Gig interfaces and 8 1-Gig interfaces. Also, my vendor has smaller controllers with 4 1-Gig interfaces that would let you distribute the controllers while managing then from the master controller (or a pair of controllers). We considered a distributed model but our network architect had no worries about the added traffic across our cores with the centralized model. We have a 10-Gig backbone, 2-Gig portchannel to the access switch, & 1-Gig ports on our access switches. The 802.11n APs have Gig interfaces.

My issue is that you are trunking everything from the edge to the network core to process and then switch to available resources. Unless you are installing 10G at the core or many, many 1G ports then I feel that you run the risk of network saturation from traffic from the AP at 802.11n speeds. This is vendor agnostic as far as I can see since oversubscription is a component of all of the centralized controller environments that I know of. I like the edge switching architecture that several vendors are promoting, Trapeze, Hi-Path Wireless and Aerohive are at least three vendors that have edge switching in the product line. Of course, Aerohive is completely edge switched and the others offer that for certain classes of traffic. GB edge switches are generally cheaper then core switches but maybe that is our enevimrnt and not typical in other places.

We now have almost 600 802.11n APs on 3 controllers that are managed centrally from the master controller. We can handle up to 500 APs per controller (2000 per chassis). This allows you to standardize configurations & OS versions. We are supplementing this with Airwave Wireless Management Suite for monitoring. We moved from 450 Cisco 1231G "fat" APs. The centralized solution scales much better for us. From: Smith, Todd [mailto:[email protected]] Sent: Friday, February 27, 2009 4:28 PM Subject: Re: Aerohive 340AP I reviewed their product in our environment and it worked pretty well. I don't think that we are going to be purchasing anything this year due to the economic downturn but they are on my short list as well as Xirrus and Meru simply because they use non-standard architectures. My personal opinion is that centralized controller environments don't scale very well when you are considering large 802.11n rollouts.

Competitors like to poke holes at their product, but my (un-tested) impression is that it's pretty solid. If you ask for references, they do have some small to medium-sized build outs, but I'm not sure if they have any 500+ AP installations, yet.

Is interesting- they are a controller-less model, that *seems* to scale and compete with controller-based functionality based on the glossy. No idea how they are on the likes of fast roaming, etc. But part of my brain yearns for the days when there were no controllers, and wireless life was a lot simpler. (You never see WLAN controllers in Norman Rockwell paintings). Is anyone using Aerohive, even on a small scale? Lee Lee H.
