It’s great to hear Aruba is adding features such as “automated RF management” that Cisco has had for over a decade. In another ten years maybe they’ll catch up to Cisco’s CleanAir technology? :D
In all seriousness,. if you’re talking specifically about AP updates, cisco has had AP code pre-download for years, resulting in between 2 to 4 minutes downtime when rebooting a multi-thousand AP controller. Not hitless, but low impact for sure. If you make use of Prime 3.3 or above, you’ve got Rolling AP Upgrade, ensuring that AP’s are updated and rebooted in defined groups so that clients are minimally impacted i.e. they roam to another AP while an adjacent is being updated. It’s not hitless since the client must roam, but it’s as transparent as you’re going to get. In my opinion, the only way we’re going to see better results for enterprise WiFi in EDU will be as customers transition to cloud-based managed-services. In this scenario, the vendor gains significant visibility on everything deployed in the field and isn’t waiting for a customer to decide to open a case and do all the necessary log/data collection e.g. Meraki. The campuses in our consortium that had been on Aruba have been migrating to Cisco this summer. Since the purchase by HP, support and innovation has waned, with bugs they’ve hit not being addressed. Clearly, like the difference in mu and Lee’s Cisco experience, it’s not all rainbows and unicorns on the Aruba side either.

We can now upgrade all or part of our wireless network with zero downtime. We also are in the process from moving from 3 independent systems (campus, remote, LPV) to a single unified system, simplifying configuration and adding more consistency..
