ITD: Learn how to deploy ITD in 10 minutes

ITD (Intelligent Traffic Director) is being deployed by a large number of customers, and it is saving them massive CAPEX and OPEX, while providing unprecedented scale and high availability.

Here is a 10 minute video that shows step by step ITD deployment.

 

ITD is shipping on Nexus 9k/7700/7k/6k/5k Series of switches. ITD won the Best of Interop 2015 in Data Center category.

My take on the integrated infrastructure buzz

I recently created a playlist of my favorite 80’s, 90’s and current songs. Listening to the playlist in shuffle mode, I noticed the stark contrast and evolution of the recording quality from the old classics to the current stuff.

Thank you Pink Floyd and Apple

I have to admit that the quality does get progressively better overtime, but in some cases tunes just sounded over-engineered, especially on the digitally recorded tracks. As good as they may sound, they often lack the warmth of reel-to-reel tape deck recordings. I am sure someone is busy developing an app to fix that.

It actually makes me wonder how some artists are able to pull some of those over-engineered studio songs off on a live stage, and some do a great job. But these days, concerts are as much about the show, not just the music – thank you Pink Flyod for setting a trend.

But I digress: what digital allows you to do is fix stuff in the mix with a simple mouse click, versus having to re-record part of, or all of the tracks. That is time and money saving stuff. It is streamlined sound engineering workflows at it’s best.

And it has opened up a whole world of possibilities for recording artists, including making mediocre ones sound pretty amazing. In fact, anyone with Garage Band installed on a MAC (and some talent) can sound pretty good these days. Thank you Apple.

Is your data center stuck in the tape-deck age?

Similar evolution has occurred in data centers around the globe. An IT environment of disparate servers, storage, and networking systems all managed in silos is a thing of the past. Or is it?

The unfortunate reality for many organizations is that their data centers are stuck in the tape deck age and associated laborious workflows. The result is that much of today’s IT budget is still being consumed by keeping the data centers humming along. That comes at the expense of real innovation.

It’s no surprise that in today’s connected-everything world, businesses and organizations off all sizes rely heavily on IT. And in that world, you need an infrastructure that is up to the task: an environment that is agile, secure and simple to manage with few resources.

Once you have that in place, your talented IT folks can turn their attention to focusing on real innovation that can lead to tangible business outcomes, rather than just keeping the lights on – just as talented musicians should focus on the music.

So what a novel idea to have an environment that combines compute, storage and networking into a pre-validated, fully integrated design that can be centrally managed? Enter the idea of integrated infrastructure. By no means is this a new concept. After all, many vendors now claim they deliver integrated infrastructure. Or can they?

I can’t speak for other vendors, but can say that Cisco has teamed up with the best in the industry to deliver pre-validated (so you know it will work together), integrated systems.

And they work just as advertised. I recently discovered this when I picked up my personal hardcopy of Unleashing IT.

ITD and RISE: New innovations at Cisco Live San Diego

ITD (Intelligent Traffic Director) and RISE (Remote Integrated Services Engine) have been helping Cisco partners and customers save massively on CAPEX and OPEX, while providing unprecedented scalability, high availability and ease and deployment. We had several events at Cisco Live San Diego 2015:

  • ITD and RISE Whisper suite meetings for Nexus 9k/7k/5k. For further discussions, please email to nxos-itd@cisco.com
  • A large number of people came to ITD Booth in the World of Solutions, to watch a demo.
  • Breakout sessions :
  • New innovation demo at the Hub:
    • ITD and Analytics Driven Green Networking : First prize winner in Hackathon 2015
  • ITD won the Best of Interop, 2015 in Data Center category. Read blog.
  • Nexus 7702 announcement : Nexus 7702 has a sweet spot in being a “services chassis” with RISE and ITD.
  • Nexus 5k/6k : RISE and ITD are now shipping: NX-OS 7.1.1N1(1)
  • Nexus 9k : ITD is now shipping: NX-OS 7.0(3)I1(2)

We hosted 1:1 customer meetings in whisper suites, during Cisco Live 2015 in San Diego. We had BU Executives, Product Managers, and Engineering Managers on  site to meet with customers. It was a unique opportunity for customers to engage directly with the Business Unit. For further discussions, please send email to nxos-itd@cisco.com.

ITD: Winner of the Best of Interop 2015

When the Best of Interop 2015 award winners were announced at the Mandalay Bay Convention Center in Las Vegas, the ITD team members couldn’t control their emotions. This team is well known to work in a startup-mode — comes up with new ideas, builds a prototype, demonstrates it to the executives and SEs, goes into execution mode, and delivers a world class solution.

As the leader of this team, I was asked by several media representatives for an interview. Here is an interview by Information Week news desk (watch full-screen for HD):

ITD (Intelligent Traffic Director) is now shipping on Nexus 9k/7k/5k series of switches.

Here is an informative blog on ITD.

To flow or not to flow?

NetApp’s newest storage operating system, clustered Data ONTAP (cDOT), leverages a backend of Cisco Nexus switches for it’s cluster interconnect network.

When configuring the switch/cluster ports for use with cDOT, the best practice is to turn flow control off as per TR-4182. In fact, that happens to be the recommendation for normal data ports as well. Why is that? Before we get into that, let’s cover the basics…

What is flow control?

Flow control is a mechanism used to help manage the rate of data transfer between two devices. This is done to help prevent a source evice from overwhelming a destination device by sending more packets than the destination can handle. These scenarios can occur if a source device is faster than the destination device (CPU, RAM, NIC, etc). This can also happen if the source is intentionally trying to flood the destination via a malicious Denial of Service (DoS) attack.

Flow control can be enacted for send or receive packets, or both. It can be hardware or software based. It can occur at multiple layers of the OSI model

For a real world analogy to flow control, think of how dams work. A dam will be installed to control the flow of water on a river, usually to create lakes or reservoirs. Dams can be used to adjust the water flow to prevent flooding, depending on rainfall. Network flow control does pretty much the same thing – it prevents data floods. Read More »
