Building “Intelligent” and Highly Automated Data Centers

Friday, February 19th, 2016

I’ve been fortunate to work in a space where I’ve had exposure to see and discuss infrastructure and architecture/design of some of the most highly utilized and scalable networks in the world. It’s fair to say living in Silicon Valley has definitely had a positive contribution as I’ve probably learned just as much outside of work as I have while on the job. (more…)

Dell Open Networking and SDN – All About Disaggregation

Sunday, May 10th, 2015

Dell Open Networking
When Dell first announced its Open Networking initiative a little over a year ago, they were the first major networking vendor to do so. Very similar to what Dell did for servers, Dell is now doing for networking – allowing customers to choose their hardware and then choose what operating system they want to install. (more…)

6WIND – From Data Plane Acceleration to Virtual Appliances

Data Plane Acceleration with 6WIND and Intel DPDK

Data Plane Acceleration with 6WIND and Intel DPDK


6WIND is an interesting company I’ve been following for some time now, initially out of curiosity, and then out of more curiosity :-) . They first started as a networking software company claiming to solve performance challenges for software defined networks (SDN) and network function virtualization (NFV). How you ask? They leverage the capabilities of multicore processors and Intel’s Data Plane Development Kit (DPDK) to allow direct access to the data plane enabling a zero-copy mode from network to CPU! (more…)

Minecraft for $2.5 Billion – Yes, ‘the App’ is King

Tuesday, March 10th, 2015

I’m still not completely over the shock from last November when I learned Microsoft had bought Mojang, the company behind Minecraft, for $2.5 billion dollars. Let me repeat that: “$2.5 BILLION”; you heard right. Markus Persson, the 35 year-old original and main developer with 71% stake in Mojang became an instant billionaire and a member of the Forbes World’s Billionaire list overnight. That’s right, Markus Persson is now #1415 with an estimated worth of $1.3 Billion according to Forbes. (more…)

Dell VRF-lite & VMware NSX: Multitenancy Across Physical & Logical Networks

Saturday, December 20th, 2014

Please checkout the white paper Dell Networking: Multitenancy Across Physical and Logical Environments with VRF-lite and VMware NSX. In the white paper I discuss use cases and how NVO and VRF-lite can be used together to deploy a consistent multitenant framework across logical and physical networks. In this short blog, I expand on the concept I presented in a prior blog, Multitenancy on Dell Networking Switches via VRF-lite, of how NVO and VRF-lite together can be used to deploy a consistent multitenant framework across logical and physical networks.

Dell Networking and VMware NSX: Bridging Between Logical & Physical Networks

Wednesday, November 5th, 2014

In a prior blog, Creating Logical Networks and Services with VMware NSX on Dell Infrastructure, I discussed how easily VMs can be moved from physical (VLANs) to logical networks (Network Virtualization Overlays or NVOs). In practicality, there will almost always be some physical resources on a network that are not virtualized or remain on the physical network (VLANs). So how can VMs on a logical network communicate with resources on the physical network?

One method of communication can be done with the VMware NSX L3 Edge Services Router. However, if you want to just bridge between the logical and physical entities such as bridging between VXLAN to VLAN, the VMware NSX L2 Gateway can be used and this specific use case is discussed in more detail in this blog.

Creating Logical Networks and Services with VMware NSX on Dell Infrastructure

Thursday, October 16th, 2014

If you haven’t already, please checkout the Dell-VMware NSX Reference Architecture (RA) whitepaper. In the reference architecture I explain in detail the foundational NSX-vSphere components and also how Dell can provide a complete end-to-end infrastructure (servers, networking, storage) to support a robust SDN solution with NSX. In this blog, I will provide a quick overview, some insight on NSX, and examples of VMware NSX deployment with a complete end-to-end Dell infrastructure. (more…)

Facebook – Not Your Typical Network Engineers

Friday, May 24th, 2013

Facebook HeadquartersA few weeks ago I got an invite to attend a Facebook Open House event which just occurred yesterday. I usually receive invites to several of these types of events from different companies across Silicon Valley. Being an active developer and working in the high-speed networking field at the same time, I tend to attend many events focused on development but also infrastructure. I usually don’t have time to attend most events, but considering this was the first Facebook invite I had, I wanted to make an effort to attend to get not only a grasp of the technology and culture at Facebook but also get a vibe for the work-life and mentality of employees there.
