What's your largest IAP cluster?

Hi All,

 

I'm curious to know how far anybody has pushed an IAP cluster in terms of number of AP's in a single cluster.

 

I'm aware the product is "unlimited" but would really like to hear experiences of customers who may have gone to 100+

 

Me personally, i've deployed 77 as my largest and it works great!

Re: What's your largest IAP cluster?

Great topic!

But guys it would be good if you said what models are in your cluster?

 

Are they are just ap 225?


Are they 170 AP 103 and 6 225???

 

Also how many devices do you have in a high traffic hour in your clusters?

 

That information would be useful :)

 

Cheers

Carlos

Re: What's your largest IAP cluster?

Victor,

 

Do you know many devices were connected to that cluster?

 

I see now it mentions in the User Guide

 

As of Instant 4.1 relelase, Aruba recommends that networks with more than 128 APs should be designed as
multiple, smaller virtual-controller networks with Layer-3 mobility enabled between them.

 

I can't seem to find any sort of scalability guide in terms of number of clients, auths per sec and such like for the different AP models.

 

I am looking to deploy a cluster of 95, but thinking maybe I need to break that into separate ones.


If my post is helpful please give kudos, or mark as solved if it answers your post.

Re: What's your largest IAP cluster?

I have a cluster consisting of the following.

 

13 AP 135's

60 AP 104's

 

73 total AP's running OS 6.4.0.2 - 4.1.0.0, tied to Airwave OS 8.0

 

Average clients on a daily basis is around 400 users.  We had a spike of 1400 users at one point which pretty much brought the system to it's knees.

Deltr0nz-

 

Sorry to hear you had troubles with the day when you had a high density of clients. Can you share what happened that "brought the system to its knees"?  What was the impact and symptoms?  How were the clients distributed -- were they all clumped together on a small handfull of APs or were they evenly distributed across all 73 APs? 20 clients per AP should not cause any problems.   What was the authentication?  Is it possible this was a Radius server issue or was the network using PSK?

Re: What's your largest IAP cluster?

 

It was a unique scenario where almost a 1000 users were all on one level of the hotel "Conference Rooms" as it was supposed to be an outside conference and the snow in June pushed it inside for two days.  The Conference area are all AP 135's, 10 of them to be exact and it was a combination of overload on the AP's and I believe the VC as well.  Currently the VC is doing everything including being a DHCP server.  I do know that this is not all on the hardware as it was brought down due to the amount of devices connecting in a small area at the same time.

Re: What's your largest IAP cluster?

This is really good feedback.

 

I'm going to have about 85 AP225.  Probably eventually up to 1000 users, spread over them all.

 

I'm inclined to have one of the AP225 as an air monitor in the server rack and acting as preferred master.  Sort of a mini dedicated controller.  What's your thoughts?

Re: What's your largest IAP cluster?

At the time of the deployment we had about 500-600 Clients connected and didn't see any issues .
