If people are curious what Cisco does for their 3x a year Cisco Live
events (last week in San Diego there was 35TB of data transferred over
that network), there's a panel discussion about how they deploy things
and what tools they use for it.

That's the session from Milan 2014, may require a free account to view
the slides and video.
The session from San Diego is at
https://www.ciscolive.com/online/connect/sessionDetail.ww?SESSION_ID=83806&backBtn=true
Doesn't look like they've finalized the slides and video for that
session yet though.

In Milan they deployed 325 APs across 6 controllers (3 HA pairs). From
experience at the US Live events, there's 10-15K people in the main
hall during keynotes, there's probably close to 100 APs in that room
alone with the stadium antennas for the density needed. There's a LOT
of people trying to tweet during and this year periscope the keynote
speeches.

If people are interested, I know a couple of the Cisco folks tend to
lurk on this and other lists and can probably provide more details if
asked nicely.
