In a January 13, 2014 NetworkWorld article, VMware executive, Steve Mullaney, compared VMware NSX to Cisco ACI and other SDN architectures. Cisco’s Frank D’Agostino replied to those assertions in the comments section of the article. Frank’s points are abbreviated and summarized here:
1. VMware pricing model is fundamentally flawed, which is raising OpEx costs, and affecting network design decisions and scale.
VMware is charging customers per-port, per-VM, and increases the cost of networking by 2x or more, while providing lower functionality, increasing operations expense, and forcing you to adopt a different network architecture. ACI delivers more functionality with zero VM tax.
For VMware, our customers consistently report pricing starting at $50 or more per VM per month. In competitive engagements, pricing rapidly declines to $15 per VM per month, then lower depending on the negotiation. Customers do not like the per port pricing, the same as they do not like per VM pricing. All of those models get expensive and alter your designs and scale considerations.
2. Claims that ACI is a proprietary platform or policy model belies the fact that many aspects of VMware’s architecture require vendor lock-in, on top of the premium pricing model.
VMware claims that ACI is proprietary. Yet customers have to get their OVS from VMware not the open switch download, under open source license. Currently, VMware is the only hypervisor platform that locks customers into a proprietary controller – RedHat, KVM, and Hyper-V all provide open access. ACI contributions are showing up in OpenStack, IETF drafts, and through VXLAN extensions, and is providing the most open implementation in the industry – API’s, data model, and integration with 3rd party controllers. Federating NSX with 3rd party controllers, such as HP, is different that providing open, bi-directional programmability.
3. Openness is really measured by the breadth of infrastructures, OS platforms, orchestration models, etc., that are supported by the policy model, and ACI is rapidly outdistancing NSX in this area.
ACI supports any hypervisor, any encapsulation (VXLAN, NVGRE, VLAN, and even STT), any physical platform, storage, physical compute, layer 4 through 7, WAN, with full flexibility of any workload anywhere, with full policy, performance, and visibility in hardware. ACI supports Open vSwitch and allows a 3rd party controller to program ACI hardware components. Investment protection is built in supporting existing platforms, and within the Nexus 9000 products enabling you to run enhanced NXOS and ACI mode with a software upgrade.

Throughout 2013, I’ve had the opportunity to meet with services provider leaders from around the globe. Whether they are large or small, focused on consumer services or business, or engaged in video or mobility, their ambitions are very much in line with our strategy: To help them monetize and optimize their networks, while accelerating their ability to deliver their services.
- Monetize: From innovative new managed security services, to video, cloud and new machine driven (M2M) services to enable the Internet of Everything (IoE), there are a number of new incremental revenue opportunities for service providers which sit at the very center of these trends estimated at over $2.9 Trillion over the next 10 years.
- Optimize: Delivery of these new services has to be less than the cost to deploy and operate them. At the end of the day, the SP is a business, and, as all businesses, they need to be profitable. New ways to deliver these services as economically as possible are key to their success.
- Accelerate: In this dynamic marketplace, service providers need to move quickly to seize these new opportunities. Gone are the days when service rollouts can take months or quarters Instead, they need to operate at “web speed” shortening the time to provision new services from months to minutes and do it in a cost-effective way.

Last week I was in London for the Gartner Data Center Conference. As always there was a wide range of interesting topics being discussed, all very useful. Working in Cisco Data Center Services, I am interested in many data center topics, however this year I was interested to hear perspectives on SDN, how the market is evolving, and how the attendees – including many senior IT practitioners – are considering SDN adoption.
London’s Big Ben at Night
From a Cisco perspective, we were showcasing the recently launched Application Centric Infrastructure (ACI), which generated a lot of interest. There is growing awareness among our customers that ACI could do for networks and applications what the Cisco UCS has done for the server market (with UCS server profiles in the latter proving a good analogy to help customers understand the potential of ACI).
So what were some of my key takeaways from the SDN discussion I heard here? And what were the questions that in my view are still not being discussed sufficiently across the industry?

It’s hard to believe but it’s ten months since I first blogged on Cisco Domain TenSM, which is Cisco Service’s framework to guide you on your path to data center and cloud transformation. I’ve now covered all ten domains of this concise and powerful model. I’ll now collect all articles – including my most Cisco Domain Ten article around the breadth of SDN adoption challenges – into this one article as a useful summary. So forgive the brevity and please do dive into the links/URLs for more information if indeed you missed these articles first time. And if you’ve read every article and watched our VoDs, please do let me know what you thought of the series – oh, and thanks!
Going back, now, I started in December 2012, with our launch of Cisco Domain Ten, where I set the focus for my series of articles as cloud transformation. Let me summarize each article with (and for those that know me you’ll know this is a struggle ) just one sentence with the key message from each blog/domain.

Welcome back loyal viewers–this is an episode not to be missed. Engineers Unplugged is thrilled to welcome the Packet Pushers (@packetpushers), aka Greg Ferro (@etherealmind) and Ethan Banks (@ecbanks), as they discuss the underlay network. Yes, they’re showing us the underside and future of software defined networking.
Watch and see:
Welcome to Engineers Unplugged, where technologists talk to each other the way they know best, with a whiteboard. The rules are simple:
- Episodes will publish weekly (or as close to it as we can manage)
- Subscribe to the podcast here: engineersunplugged.com
- Follow the #engineersunplugged conversation on Twitter
- Submit ideas for episodes or volunteer to appear by Tweeting to @CommsNinja
- Practice drawing unicorns
And it wouldn’t be Engineers Unplugged without unicorns, a software defined one here.
Packet Pushers, aka Greg Ferro and Ethan Banks, plus unicorn!
We’ll see you next week at VMworld! Be sure to drop by the Cisco booth and try your hand at unicorn whiteboarding.
