VCE chooses Cisco ACI as SDN Strategy Instead of VMware NSX

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.

OpenFlow, HP Sentinel and Security SDN

HP Sentinel is an SDN Security application that combines a reputation database, HP VAN Controller and OpenFlow to build a Campus security solution. Here is a quick overview of the process and how you can mix existing security technology with standards-based OpenFlow/SDN to provide a useful campus security tool. This product is expected to reach the market later this year.

Blessay: Categorising SDN Network Solutions and Architectures for Understanding

SDN Strategy Map (Click for Larger Image)

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 into three categories of Micro, Centi and Kilo as well as classifying physical devices for SDN systems into three classes of Breve, Medius and Magnus.(Yeah, OK, I’m not good at names.)

cisco-head-shot

Cisco announces that it has expanded its ACI Strategy to include the Campus and WAN in the scope of the product as well hybrid cloud functionality. Some thoughts on what this means for network architects and engineers: My View – Cisco wants to maintain control and ownership of customer budgets on networking by having a […]

◎ Debating Whether Network Engineers Need to Learn Programming

network-programming-yes-but-no-opt

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 programming skills for good business outcomes. You need to decide where you want to be.

Overlay Networking & VXLAN Means MPLS in the Data Centre is Dead

VXLAN-Frame-Transformation-595-opt.png

Overlay networking has been around for a year or so now and the ideas behind it are well established. It was about 3/4 weeks ago while researching VTEP functionality in Dell and Arista switches that I realised I could build manually configured tunnels with VXLAN and get the same results as an EoMPLS x-connect with almost zero effort. More importantly, I don’t have to pay for expensive hardware that has MPLS functions or pay again for software licenses to upgrade with MPLS features.
