Does anyone else have heartburn about putting 500 (or in the future 1,000) APs on a single controller? With our deployment, 150 per controller is roughly 2-3 of our bigger buildings, and several of the smaller - but not necessarily geographically together. We can minimize an outage by putting different neighboring buildings on different WiSM blades. With 500 APs on a single controller (or 1,000 in the future), a WiSM outage could take down half the campus - or the whole campus in many cases. Seeing as our students (and faculty, frankly) see wireless as a desired connectivity method, that prospect is scary, to me.

I had just finally gotten away from a mixed code environment this past summer after putting the last 1010s out to pasture and now there's this. On our end we're working to fund replacing the WiSM 1s with WiSM 2s this summer, fingers crossed that will work out. I am very disappointed that Cisco would kill upgrades to the WiSM 1 code so shortly after introducing the WiSM 2.

It's no surprise that WiSMs are getting long in the tooth, but the part of the announcement that (I think) sucks is that we have a quantity of 3600 APs ready to get installed. These APs need 7.1 Code. WiSMs will not run 7.1 code. We have (6) 5508s, and 24 controllers on 12 WiSMs. So we have the unfortunate choices of either running a mixed code environment (yeah, that sounds fun) where 3600s may hit controllers that can't let them associate, shelving our 3600s until we get our 5508s in place and WiSMs retired at the pace we had planned on, or quickly rushing to get rid the WiSMs so we're not faced with either of the first two situations.
