Lots of people claiming that scripting works for automation and, for a few scripts or tasks, you can get a lot done for not much effort. My experiences with scripting have left me bitter and jaded. Here is why.
Takeaway – Corsa Networks is focussed on provided a hardware data plane for SDN WAN use cases.
Early last year I drew a strategy map of all the elements in a Software Defined Ecosystem for a client. I drew another one a couple of weeks back to explain how the current vendor focus on controllers, and specifically, OpenDaylight is changing the nature of the market. The comparison is striking.
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.
Dual 100G interface and 24 MILLION flow table entries for Open vSwitch ? And flow setup rates to match.
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.
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 ?
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.
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.)
