We are a K-12 system. We have 7210 controllers running 6.5.0.3 with AP models 105, 114, 115, 214, 215, 224, and 225. We do not use ClearPass. Most AP's are in dense deployment (one in every classroom, roughly 50 feet apart). I have 4 or 5 virtual AP's applied to a given AP group (depending on the site). Each VAP has a separate SSID, appropriate aruba firewall rules for the type of client connecting, and puts them on VLANs with access to various resources within our network or routes them directly out to the internet. I've gotten requests to add 2 more virtual AP's, and apply them to all AP groups. I'm wondering at what point I would start to see performance issues. I ran across a helpful Airheads post entitled "What is the effect of virtual access points on the available throughput?" which was helpful in understanding how / why having multiple VAP's can cause issues, but I wasn't really able to determine when it could become a problem for us in a real-world scenario. What's your opinion? How many VAP's do you think are too many in our kind of environment?
