18 months ago I experienced a version upgrade on the active system at a conference.
In our initial failover testing here, we had a client set up doing a continuous ping to a target. We took our network from4 controllers down to 1. The AP & client roamed seamlessly such that not one ping was dropped. My understanding was that one of Aruba's large clients demanded a system with no downtime. We can also, if desired, run different code versions within the same system.

Don’t misunderstand; it’s far better than what Cisco has, but the system disconnects the clients from the AP side of things, and hence, from a client perspective, it’s not “hitless” or “no downtime”. They just suddenly get disconnected, and they have to reconnect. It’s not the clients decision to move to a new AP. Would I like this on Cisco; absolutely. I’m not holding my breath, though. -- Joachim ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/discuss. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/discuss.
