My Aruba Atmosphere 2015 Experience

by 2 weeks ago - last edited 2 weeks ago

The Aruba HP acquisition was on everyones mind, up to this point it was rumor and the constant “no comment" was mentioned when I asked anyone at Aruba about the purchase, typical protocol when something like this is in the works. That rumor quickly became fact the day before #ATM15 was to kick off.

It used to be that roaming, even when it was poor, wasn’t a big deal in most networks that weren’t specifically supporting voice traffic. Most users of WLANs were laptop users and they were more nomadic. Modern clients are more likely to be using data and real-time services while moving and they expect the network to be transparent. This is fine when everything works great, but what about dealing with sticky clients?

Last week I attended Atmosphere 2015 in Las Vegas and while there were some big announcements (a new line of printers or something like that… I wasn’t really paying much attention), the underlying tone of the event showed the direction the market is taking. And Aruba is hands-down leading the way.

Some complain that the FCC made a mistake in their Marriott ruling and the resulting Enforcement advisory against Wi-Fi blocking. Those who disagree say an organization should be able to control the RF environment on their own property. While that sounds reasonable at first, can we even develop the rules to allow that?

Better Together @ Atmosphere

by rjfreedman on ‎02-24-2015 04:08 PM

Last year, 2014, was our first presence at Aruba Atmosphere – for myself and for Brocade – and we were graciously welcomed by the Airheads community. As new Aruba partners we had a great opportunity to showcase unified wired/wireless solutions., featuring demonstrations of our integration points with AirWave and ClearPass. Additionally, as a leader in Software-Defined Networking (SDN), our breakout sessions drew a lot of attention and we received a lot of interesting feedback from the community about their views on SDN in the campus.

Product security in the wake of Sony

by Moderator Moderator ‎12-18-2014 10:56 AM - edited ‎12-18-2014 11:04 AM

The Sony security breach has been all over the news lately, and in its wake we’ve been getting a number of security-related questions from our customers. Although there’s been no implication of wireless networks in the Sony breach, Aruba customers are justifiably worried about technology that can link attackers in the parking lot (“car park” for our non-American friends) with their internal LAN. Obviously, no IT product can make the claim of 100% security (and anyone who does should be kicked out the door) but let me at least try to explain how we approach product security at Aruba.
