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.

Here is more information about ITD:

Bumbling and Stumbling in the Data Center

What’s the klutziest thing you’ve ever done in a Data Center?

Over the years I’ve seen people drop tools, tangle patch cords and step into notched floor tiles.  Once when I was giving a Data Center tour a fellow was so intent to see how outside air was drawn into the HVAC system that he whacked his head on a viewing window.

I’ve encountered outages caused by clumsiness, too.  In one case a co-worker was lifting a floor tile and tilted the panel too steeply, causing it to separate from the suction-cup tile puller he was using and crash into the plenum below, slicing a fiber cable. Read More »

Network Dependency Mapping Helps Clean Up Our Application Portfolio

My team is moving hundreds of applications to our new Application Centric Infrastructure (ACI) platform, and network dependency mapping is the first step in this migration. Most of Cisco IT’s applications are three tiered with web and middle tier residing on the same Java Virtual Machine (JVM) connecting to a database.

A typical application may have one or more JVMs that connect to one or more databases. Sometimes the databases internally connect to other databases. Over the last five years, we have heavily invested in Services Oriented Architecture (SOA) and thus have JVMs running web services. These web services are consumed by one or more user interfaces (UI). Some of these applications have jobs that run on our Cisco Tidal Enterprise Scheduler (TES). Read More »

Part 2: How Many Servers Do You Have …. Comatose and Sitting Idle?!?!

Last week I introduced this topic, the pervasive problem of “comatose” servers in data centers, based upon an interesting recent eWeek article entitled “30 Percent of Servers Worldwide Sit Idle”, which in turn was based upon the research report by Stanford University in conjunction with the Anthesis Group.  In my blog, I described the costs of this problem, ranging from the obvious (e.g. power and facilities) to the hidden (e.g. un-used software licenses).  This week I’ll discuss why this happens and what you can do about this problem.

How Many Servers Do You Have …. Comatose and Sitting Idle?! (Part 1)

In my role in Cisco Services, I’m more interested in the challenges of technology adoption and deployment than I am in speeds and feeds, statistics and technology fads.  I actively seek out case studies where technology goes wrong – admittedly most of these examples turn out to be issues around introducing and managing the technology, rather than the technology itself.  So I have to admit, I was fascinated by a recent  eWeek article (full details below) which discussed the huge proportion – the report uncovers evidence of up to 30%!! – of (physical) servers in enterprise data centers that are typically running doing nothing!!  Yes – up to 30% – even in these days of virtualization!

How Many Idle and Comatose Servers Do You Have?!

Yes, even in your data center, it’s probably a safe bet to say that you have some servers that are not doing that much information processing today!  In this part 1 of my blog, I’ll discuss the costs – obvious and hidden – of the idle server challenge.  And next week I’ll discuss why this happens and what you could and indeed should do about it!
