Cisco Champion Radio on ACI and Nexus 9000

March 3, 2014 at 11:07 am PST
  • How ACI lets you manage a network cohesively instead of box-by-box ?
  • What a network looks like in ACI mode vs. stand-alone mode ?
  • How ACI works with network protocols like spanning-tree and TRILL ?
  • Upgrading the Nexus 9000 Series to ACI
  • When does ACI make sense for your business ?

For this new episode of the podcast with Cisco Champion, we are fortunate to have a great technical (and casual) dialog between two active members of the data center and cloud social media sphere.

LynchOnisick2

Colin Lynch (@UCSguru) based in London is a subject matter expert for Cisco UCS, Integrated Systems, Converged Infrastructure and writes also on SDN . Colin has an independant blog at UCSguru.com He was nominated ComputaCenter Consultant of the Year in 2013 .

Colin talked with Joe Onisick (@jonisick) who works for Insieme Networks, now part of Cisco. Joe writes an independant blog at DefineTheCloud.com. He talked about ACI in multiple videos and podcasts.

After attending Cisco Live Europe in Milan, Colin was at VMware PEX to have an in-depth analysis of NSX , and wanted to “challenge ” Joe on several points, which makes this conversation even more lively !

I found this dialog extremely rich, as both participants were willing to address difficult and controversial aspects of the Data Center architecture today and tomorrow,  for instance around layer 2 and layer 3,  network programmability and management, or the future of networking certification ! You will also better understand, why Cisco is heavily investing in ACI solutions, when at the same type keeps developing other paths .
A very exciting 40 mn conversation between two great subject matter experts, really passionate by this topic, spiced  with additional questions from other Cisco Champions and…humor.

Listen now to our guests and enjoy the show hosted by @commsninja.

I also encourage you to read this very didactic explanation from Tom Edsall, Cisco Fellow and CTO of Insieme Networks, in this new blog from Shashi Kiran
ACI Design Principles : The Role of SDN Overlays in Application Centric Deployement . Shashi  will publish the second part tomorrow .

As a reminder, Cisco Champion is a community of  technical professionals who are passionate about sharing their knowledge and expertise. They are ready to offer their time to help others to learn about Cisco and connect with Cisco in unique way
For Data Center and Cloud , we have now more than 40 members, who have been nominated by peers for one year . We invite them to give their opinion on market trends, Cisco solutions and products . We encourage also them to participate to our Cisco Live events , webcasts, podcasts , Google + HOA , blogs and tweet to share their experience and wisdom.

6 Tips for High Density Network Design

The guys from No Strings Attached Show just published their podcast we sponsored featuring Jim Florwick yesterday and already the verdict is in: Jim Florwick is awesome.

For those of you who haven’t had the chance to download the podcast yet (What are you waiting for?! Download  podcast) or you have a few extra minutes to scan a short blog to decide whether or not you want to download the podcast, I asked Jim what his key takeaways are when it comes to high density design.

Here are Jim Florwick’s 6 tips for HD network design (for the REAL meat, tune into the podcast):

  1. High density client environments are quite common with today’s users being very connected – today’s users are always connected.  With planning, this can be managed quite successfully.  Understand the limitations, be aware of how legacy requirements will affect the outcome, and set expectations accordingly. Efficiency is key and removing some of the blockers (legacy) first is essential.
  2. 802.11ac represents another quantum leap forward in technology and will eventually allow a much richer user experience.   It is a transition that must be managed and balanced against your current mission requirements.  Evaluate channel/bandwidth requirements carefully.  Monitor the mix of client devices operating in your environment and update frequently.

Deploying, Testing, and Tuning 802.11ac

By now you’ve probably heard quite a bit about the newest generation of Wi-Fi, 802.11ac.  I’ll save you the gory details, just know it’s about 3x faster than 802.11n and will help to improve the capacity of your network. Jameson Blandford and I were recently guests on the No Strings Attached Show podcast with Blake Krone and Samuel Clements (Click to listen to the podcast).

I wanted to follow up the podcast with a blog to go over considerations for deploying, testing, and tuning 802.11ac.

Considerations for deploying 802.11ac

Switching infrastructure

The first question you’ll want to ask yourself, is, if your switching infrastructure can handle 11ac?  The answer probably is, yes.  The things to consider are the port speed and power-over-Ethernet (PoE) capabilities.  You’ll want the access point to have a gigabit uplink to the switch.  Each 11ac access point could potentially dump several hundred megabits per second of traffic onto your wired network.  It’s also not a bad idea to have 10 Gig uplinks on your access switches to distribution or your core.  If you have even just a couple access points on a single access switch, you may quickly find yourself wishing you had 10 Gig uplinks.

Next you’ll need to consider how you will power the access points.  If you are like the majority of our customers, you will use PoE from your switches.  While 11ac access points require 802.3at (PoE+) for full functionality, the Aironet 3700 will run happily on standard 802.3af PoE.  In fact, it remains 3 spatial-streams on both radios, so performance does not suffer because you have a PoE infrastructure.

Live: 802.11ac with No Strings Attached

Coming off a busy week at Interop Las Vegas, we have recorded another info-packed podcast with the popular wireless networking podcast group “No Strings Attached Show”. The topic for this podcast covers the gigabit wireless technology, 802.11ac which if you attended Interop, you know this is a very hot topic (“I’ll take enormous understatements for $600, Alex”).

However, it is not just a discussion on what is included in the standard. Blake Krone and Sam Clements from No Strings Attached interview our Mark Denny and Brian Hart as they discuss a number of topics related to 802.11ac technology including the following:

-          The 802.11ac Wave 1 Radio Module for the 3600 Access Point, the availability and best practices for upgrading the 3600 AP with the 802.11ac Module

-          Segments of the enterprise market where 802.11ac technology is generating the most interest Read More »
