Just because I share my opinion publicly doesn’t make me an analyst. I’d rather be known as an Activist Customer than a Citizen Analyst since there is widespread perception that industry analysts are biased or easily influenced.
I doubt that anyone bought a Vblock because it was a market leading networking strategy. I’ve been a supporter of VCE but today I’m doubtful that choosing Cisco ACI is good strategy for their customers. My view is that most customers buy VCE Vblocks as a VMware platform. What VCE offers is a services package of fully supported storage, compute and networking that removes customer risk around VMware deployments while reselling EMC & Cisco hardware.
One of the key business drivers behind SDN is to extract value from network connectivity. Before SDN, the functionality derived from connecting servers to switches was inherently valuable. In the post-SDN era, the network has services value instead.

Collection of useful, relevant or just fun places on the Internets for 7th March 2014 and a bit commentary about what I’ve found interesting about them: The Definitive Guide to NSX Gateway Uses Cases – J-Net Community – I missed this earlier but it’s a good summary on NSX use cases from the launch.

This press release from Huawei really grabbed my attention because it’s an MPLS enabled router that is finger sized and built for carrier networks.

A common complaint about vendor certifications is that they don’t prepare you for the real world. Well of course not. Neither did high school or college. And thinking about it, my University education wasn’t much better.
As someone who knows that Amazon AWS is a really expensive method of buying compute & storage, I was much amused by the following slides from a presentation by Terry Wise, Director, Worldwide Partner Ecosystem during a recent conference. You might enjoy a good laugh too.
In short, connectivity is now commodity and it is services that are hard. Understanding this point is key to understanding the SDN market. I take the view that SDN assumes that connectivity is a cheap, low cost and low value business function.
100% utilisation means that you are a traffic jam in the workflow. Don’t overcommit yourself.
The impacts of market commoditisation in networking happen are occurring in more segments than just whitebox switches and network operating system. The Internet is steadily progressing towards the exclusive use of HTTP for all communication and bypasses the plethora of protocols that were once in use. And even within HTTP, the current direction of the HTTP/2 protocol standards and it’s proposed of TLS encryption for all protocols will radically change many aspects of the Internet.
I’m really pleased that Interop have asked me to talk more about blogging and to go deeper on the topic and the result is a new session – Interop Las Vegas – How to Be a Tech Blogger.
At NANOG 60 this happened – “￼Help! My Big Expensive Router Is Really Expensive!” Over the past few years, we’ve seen the data center switch market explode with commodity chips, open source software, and the concepts of SDN. All we have seen in the routing space has been bigger routers that need more power, cooling, […]
Your employer is having financial problems. There is a lot of pressure to do “more with less”, to pull together and “do the deals”, close the sales before end of quarter. But really, what do you owe your employer in the modern era ? What is best for you ? This situation is one where the modern paradigm of fail fast, fail often and fail early applies.
Netronome makes silicon that accelerates networking by enhancing the network adapters to very high performance. Want to run Open vSwitch at 15 million flow setups per second ?

TL:DR A recent project bought a low-cost network for the data centre. It cost less one-third of the market leader & half the cost of a well-known merchant silicon vendors. As a result, it is planned to last for two, maybe three years before it will be replaced. From this project I learned that … [Read More...]
Recently, Dave at DavesBlog made some rather startling observations that Verizon is throttling Netflix traffic, backed up by a comment from some low level help desk staffer that this is true. Taking a casual comment as "truth" is wildly unreasonable. On the Internet, it is very hard to pick the … [Read More...]
I've been digging deeper into the SDN architectures over the last few days and there may be a pattern starting to emerge. I'm currently figuring that there are four broad classes of SDN technology that you can fairly neatly classify the current products from vendors. I'm classifying SDN Solutions … [Read More...]
Most people refer to the “Data Centre Network” as though it was a single network. In practice, data centres have a number of individual networks. Each network is specifically designed for a specific purpose and function. A typical data centre network design has about five individual networks that … [Read More...]
I was eating the last of my toast as I sat down into the driver seat of my "CloudCar". Customer visit at 09:30am. As I slipped my SmartPhone into the cradle, the dashboard screen came to life and opened the NavSat app with an error message that my maps were out of date and would I like to download … [Read More...]
The rise of Software Defined Networking has led to a steady stream of emails from network engineers asking whether they need to learn to programming in the future. After consideration, I currently think that the answer is mostly no but some percentage of networking people will gain and use specific … [Read More...]
Many people are predicting that networking will become a heavily commoditised with cheap white box hardware in the next few years. But I don't believe commoditisation will happen the way that most people expect. So in this article I'm working through different ideas and concepts on product pricing … [Read More...]
Lots of talk about simplicity recently and the fact that networking is too complicated and inflexible. There are a number of choices that you deliver simplicity in Overlay Networks. Least Functionality - One choice is to reduce the network to most minimal and least functionality. But we tried … [Read More...]
