You’re probably thinking: Chris, you’re a leader at Cisco, of course you want me to migrate to 802.11ac. That, my friends, is where you are wrong. There is no simple answer to the question of whether you should move your network to 802.11ac. Here’s my simple rule of thumb:
There is no premium for 802.11ac from Cisco. If you are deploying new Access Points’s today, you should be buying 802.11ac. If you’re not buying, you are probably satisfied with your network and how it will handle the growth of more and more clients associating with your network and the bandwidth demands that come with that client demand. If you feel you have a plan to handle this demand, then you are one of the few that can pass on 802.11ac.
That said, there is a strong ramp up for Cisco 802.11ac products in the market, the AP3700 is the fastest ramping access point in our history and we have yet to see if the AP2700 will claim that crown in the coming months. ABI Research estimates that currently 50% of new device introductions are 802.11ac enabled, a statistic expected to increase to 75% by the end of 2015. This is enough proof of the overwhelming interest in adding the benefits of 11ac to networks. Let’s take a step back and consider the basics of why people are moving to the new standard.
Today, everything is about getting what we want, when we want it. Instant gratification. It’s not just the millennials—we’ve all been conditioned to expect things within seconds. Could you imagine the days pre-Internet if you had the capability for on-demand movies? Read More »
It’s been a very busy few weeks. The Data Storage Innovations (DSI) conference, the Ethernet Summit conference, EMCWorld, and next week at CiscoLive, I’ve been starting to talk about a new concept in Data Center storage networks called Dynamic FCoE. Understandably, there have been a lot of questions about it, and I wanted to try to get this blog out as quickly as possible.
The TL;DR version: Dynamic FCoE combines the best of Ethernet Fabrics and traditional deterministic storage environments to create massively scalable and highly resilient FC-based fabrics. If you thought you knew what you could do with storage networks, this takes everything to a whole, new level. Read More »
As I start to explore more and more information about Software-Defined Networking and Programmability in the Nexus portfolio, I’ve been fortunate that there have been a lot of people helping me learn along the way. I thought I’d share some of these as it gave me a bit more insight into some of the more holistic perspectives that I’ve been trying to get my head wrapped around lately.
I’m still starting off at a rather high level, though I’m spending more and more time getting deeper into the tech. Every once in a while, though, I need to look up and make sure that I’m swimming in the right direction. It’s really easy to get mired in the details and forget the bigger picture. Read More »
This is an amazing episode of Engineers Unplugged, where two technologists from the community, Hal Rottenberg (@halr9000) and Colin Lynch (@ucsguru) discuss how ACI disrupts traditional networking thinking while leveraging current networking skills. It’s a great tutorial for anyone looking to understand what application centric infrastructure really means.
Will network engineers all become programmers?
Watch and see:

This is Engineers Unplugged, where technologists talk to each other the way they know best, with a whiteboard. The rules are simple:
Episodes will publish weekly (or as close to it as we can manage)
If you guessed that it logs into a switch at 172.16.66.1 and disables interface F0/1 for 5 seconds and re-enables it, then you guessed right.
Let us talk a little about putting the “ability” in programmability. Did I code in college? Yes. Was I good at it? Not really. Dijksta’s algorithm (the actual coding bit) drove me crazy, however, actually using and operating networks quickly became my cup of tea. I became a network geek. Subnets? Awesome! Cisco CLI? Sweet. Using Enhanced Interior Gateway Routing Protocol (EIGRP)? Yay! AVVID? Even better. But I never wanted to see C++ or another “program” again.
Fast forward to 2014. I’m still a networking guy but now I’m seeing code again. The good news is, maybe like you, I hang out with some really cool people. I challenged a couple of them to help me demonstrate program “ability” to networking people on the show floor at CiscoLive Milan…with me as the test subject! Read More »
