Takeaways from VMUG in Chicago
Last week, I had the opportunity to travel to Chicago to attend the VMware User Group conference. It was a great event where I had the opportunity to meet and speak with many server, storage and network team members. One point that struck me was that the importance of the network is becoming clearer to everyone with a stake in the data center — and we couldn’t be happier to be leading the way.
Here are a couple of my observations from Chicago’s installation of the show:
- Beyond applications: In the past, VMUG conferences have been heavily attended by application and server teams. This year, I found that many of the attendees were networking and storage decision-makers and administrators. To me, that signals how much storage is being virtualized and how important the network has become in virtualized environments. The success of these environments will soon depend on the network and the need for cooperation and interdependency of the applications, storage and networking teams is clear.
- Hyperconverged layers: There’s a continued emphasis on the hyperconvergence of storage and compute—and the network is getting into the mix. I had a lot of conversations on why a converged network is a Continue reading

In a recent blog post Tom Hollingsworth made a great point: we should refocus from fighting one fire at a time to preventing fires.
I completely agree with him. However…

The flow-graph application, shown above, generates a real-time graph of communication between hosts. The application uses a simple sFlow-RT script to track associations between hosts based on their communication patterns and plots the results using the vis.js dynamic, browser based visualization library. This example can be modified to track different types of relationship and extended to incorporate other popular data visualization libraries such as D3.js.
Each of the examples has a server-side component that uses sFlow-RT's script API to collect, analyze, and export measurements. An HTML5 client side user interface connects to the server and presents the data.
The sFlow-RT analytics engine is a highly scaleable platform for processing sFlow measurements Continue reading

Python – Lists and Dict(ionarie)s
One of the fist things you’ll most likely encounter with Python are the datatypes lists and dicts. While they initially seem quite simple, things can get awfully complex, awfully fast when you start intermingling the two datatypes. So we’ll start with the basics, then dive into some more complex examples.
Lists
Lists are defined as ‘a collection of different pieces of information as a sequence under a single variable name’. So that’s a fancy way of saying it’s just a list. In Python, lists are defined by using the ‘[]’ brackets. So for example…
# A list with one item list = ["Jon"] # A list with multiple items list = ["Jon", "Matt", "Bill"] # An empty list list = []
Items in lists can be accessed by index. For example…
# A list with multiple items list = ["Jon", "Matt", "Bill"] print "The second name in the list is " + list[1] # Result The second name in the list is Matt
We can also iterate through the list with a simple loop…
# A list with multiple items
list = ["Jon", "Matt", "Bill"]
for name in list:
print name
# Result

Network Automation: Be Bold!
I’ve had something on my mind concerning network automation, and I think it’s worth mentioning it here.
There’s been a lot of talk - including plenty from myself - about using tools like Ansible for creating network configuration files; that is, text files that contain configurations for network devices, usually a list of CLI commands. And this is a great first step, certainly if you’re new to network automation.
It’s really not that hard to generate configurations. You can do it in about five lines of Python, or you can stick with that Excel spreadsheet powered by macros (you know who you are). I challenge anyone to tell me that Ansible is better at generating config templates than Excel. The reality is that it’s not - and it’s hardly attempting to be.
So, for the sake of making a point, let’s say the generation mechanism doesn’t matter. Let’s concede that this is the wrong optimization to be making. The question becomes - what is the right optimization?
I think the bigger problem to address is that of treating our networks like fragile snowflakes. I can’t tell you how many times I’ve logged into a device, and felt like I was Continue reading
