PlexxiPulse—A Big Week for Plexxi and a New Era in IT
If you’ve been following Plexxi in the news and on social media, you will see that we announced our new CEO, Rich Napolitano, who comes to us from EMC to continue the company’s expansion and help lead Plexxi into a new era of IT. Rich has been a friend of Plexxi’s for a while; he sat on our Board of Directors before taking on his current role CEO. You can read Rich’s first blog post on why he joined Plexxi here. We also announced this week that Tim Lieto has been named senior vice president of sales and customer service to lead the company’s worldwide sales and channel effort. It sure is an exciting time for Plexxi, and we’re thrilled to have both Rich and Tim on board!
In this week’s PlexxiTube of the week, Dan Backman explains how Plexxi’s Big Data fabric solution is managed.
Jim Duffy wrote an interesting piece in Network World this week questioning whether Cisco and Arista should develop versions of their operating systems for bare metal hardware (similar to Cumulus). The industry shift that is taking place here is actually very simple. Research and development spend reflects where the value and Continue reading
Network Technology Shifts towards IT’s Third Platform
The requirements for next generation applications in the Third Platform era have a profound impact on the network. No longer can we treat the network as a piece of infrastructure that just needs to be present. It has to drastically change to become a fundamental component of the next generation application. Mike went through some of the network implications of the new era application properties in his post yesterday:
- Horizontally Scaled
- Agile
- Integrated
- Resilient
- Secure
The change towards Third Platform IT infrastructures is more than evolutionary. The compute, storage and application frameworks and infrastructures started their transformation a while ago. These types of shifts take time, but networking has not run at the same pace of change to keep up. Up to recently, networking’s great contribution to the changing IT world was a move from a multi tier network into a two tier network with a new name. Hardly transformational to say the least.
Migration and Crossover Technologies
A move towards a new platform does not happen overnight. It takes time and more importantly, it takes several technology iterations to get there. A migration from the current platform requires migration technologies: pieces and parts of what we will ultimately Continue reading
The requirements for IT’s Third Platform
With the blurring of technology lines, the rise of competitive companies, and a shift in buying models all before us, it would appear we are at the cusp of ushering in the next era in IT—the Third Platform Era. But as with the other transitions, it is not the technology or the vendors that trigger a change in buying patterns. There must be fundamental shifts in buying behavior driven by business objectives.
The IT industry at large is in the midst of a massive rewrite of key business applications in response to two technology trends: the proliferation of data (read: Big Data) and the need for additional performance and scale. In many regards, the first begets the second. As data becomes more available—via traditional datacenters, and both public and private cloud environments—applications look to use that data, which means the applications themselves have to go through an evolution to account for the scale and performance required.
Scale up or scale out?
When the industry talks about scale, people typically trot out Moore’s Law to explain how capacity doubles every 18 months. Strictly speaking, Moore’s Law is more principle than law, and it was initially applied to the number of transistors Continue reading
An industry in transition
The tendency of most companies is to talk strategy and vision. Almost every technology company can paint a future that is somehow more elegant based on their product’s fit into customer plans. And, as a sales leader, if you find a company whose vision you find compelling enough to inspire you to share it with customers, you’re probably feeling pretty good about things.
But sales is ultimately measured on wins and losses. And there is no taking solace in a grand vision if you cannot meaningful and immediately make a difference in a customer’s life. So as much as sales is about demonstrating a better future, there is no substitute for solving immediate pain.
This means that the ideal landing spot for anyone in a sales role is a company that thinks big but is committed to enabling the game changing vision for today’s customer problem set.You want to be a part of an organization that wants to do nothing short of changing the world, but who has the focus to do it in ways that provide immediate tangible benefit.
I am certain I have found that in Plexxi.
Before joining Plexxi as the head of Worldwide Sales, I Continue reading
Leading Disruption
My entire career has been spent finding disruption and cultivating the technologies needed to convert that disruption into real business value for customers. It is with that objective in mind that I am thrilled to join the Plexxi team as Chief Executive Officer, alongside my good friend and colleague Dave Husak, who will lead our product development efforts.
We are in a unique moment in time, with massive technological and business model changes underway in parallel. Everything we know about compute, storage, networking, and applications is in transformation. Changes like this have not occurred in over twenty years. And change of this magnitude breeds opportunity.
My decision to join Plexxi was actually many months in the making. In my previous job leading EMC’s Unified Storage Division, I drove over $30B in revenue during my tenure with over 2000 people in the global organizational for which I was responsible. In that role, I had a fairly unique vantage point of the IT industry as a whole. I certainly spent time viewing the landscape from my position within a major infrastructure manufacturer. But I also got to engage with channel and technology partners across the entire IT spectrum to see how they Continue reading
PlexxiPulse—Conversations on the SDN “Technique Churn”
Ethan Banks (@ecbanks) initiated an interesting Twitter conversation last weekend by claiming that the constant “technique churn” within organizations that utilize SDN and NetOps is doing the networking industry a disservice. Banks feels that ever-changing frameworks make it nearly impossible to thoroughly understand new technologies. Our own Mike Bushong (@mbushong) took a deep dive into the subject on the Plexxi blog this week in response to those claims. Be sure to check it out before you head out for the day.
In this week’s PlexxiTube video of the week, Dan Backman explains how Plexxi’s Big Data fabric solution can run both L2 and L3 simultaneously.
SDN Users’ Wish Lists Sounds a Lot Like White Box Switching
In an article this week for SDN Central, Craig Matsumoto looks at users that are growing increasingly tired of vendor lock-in and therefore turn to white box switching to provide additional interoperability. In my opinion, the interoperability provided is interesting as it is not a property of vendor intentions. When we accelerate the pace of innovation, there are going to be new capabilities that get added to gear. At the time of first-add, no one else supports the feature. At Continue reading
The Philosophy of Network-as-a-Service
In the world of Anything-as-a-Service (I will leave the acronym to your imagination), Network-as-a-Service is not a new term. In fact, it even has its own wikipedia page which will tell you it has been used for many years now, well before the current set of service related terms in IT have become popular.
Like most high tech industries, we get somewhat carried away when we have some new terminology and quickly overuse and overload them, watering them down to be meaningless or at least highly confusing. But when you cut through the clutter a bit, the as-a-Service terminology most certainly articulates a shift in thought process and behaviors on how we provide and consume IT resources.
The IT organization has always been a service organization, there is nothing much new there. From the days of mainframes and supercomputers, their job was to provide access to these expensive resources and maintain them. They provided environments that allowed the users to conveniently consume these abilities, and the business applications that ran on top of them, whether those were financial systems, email, uucp news (remember those days) or the basic ability to run user created jobs.
With the distribution of compute and Continue reading
The Case for Hybrids
Plexxi along with Piston Cloud, Colovore, and King Star Computing published a white paper a few months back looking at the cost of a private cloud running OpenStack in a hosted environment versus renting compute instances from Amazon. The details are here. The short story is that in this analysis, at about 129 Cores, the costs for a private cloud start to become better than public cloud. Certainly the efficiency of colocation, commodity computing/storage, and an application oriented network fabric integrated tightly with a cloud orchestration management platform (OpenStack) has a lot of built in efficiencies so its not surprising to see the result of this analysis.
We’ve Seen this Story Before, Haven’t We?
Similarly, years ago in software development circles, the debates about outsourcing were fierce and emotional. Back then, much centered on the cost leverage available to companies to move development to low-cost areas such as India, China, and Eastern Europe. However, over time, companies found that while cost gave them flexibility and resourcing mite, the more important benefit ended up being owning development resources and presences close to emerging markets while leveraging outsourcing partners for on-demand resource expansion. Wow, sounds a lot like Colocation + Hybrid Cloud Continue reading
The power of Clustering Illusion when managing image
As humans, we are predisposed to finding order out of otherwise random data. When we look at clouds or even a mountain ridge, we find shapes that are familiar to us. When we see data, we instinctively search for patterns to help make sense of what might appear to be random information. It might be our inherent need for understanding. Or maybe we are just programmed to compare things to stuff we already know. Whatever the underlying cause, it’s a powerful trait that virtually all of us share.
Understanding that people want to put information into buckets and draw conclusions, are there things that we can be doing to help manage our own image?
Walking a Vegas game floor
Maybe you have walked a gaming floor in Las Vegas, turning your head as you are assaulted by the lights and noise that accompany the gambling experience. While perusing the various games, have you ever spotted a roulette table and noticed that the last 6 spins have all come up black? The next spin is bound to be red!
Of course we all know that the likelihood of a red on the next spin is statistically the same, regardless of what Continue reading
SDN and legacy companies: laggards or pragmatists?
There was an interesting Twitter thread over the weekend initiated by Ethan Banks (@ecbanks). He commented that there was too much technique churn in SDN and NetOps (the networking equivalent of DevOps). His point was that in the face of all the change in how to do things, it left users in an impossible spot. How can up pick up a new technology if the frameworks around how to use it are consistently changing?
His conclusion was that we cannot herd these cats. But what is really going on?
No consensus on operating models
The most basic truth here is that there is no real consensus on operating models around any of the new technology. While there are rough agreements on a few architectural principles (and even there, far more is in the air than well grounded), there is really not a lot of best practices to which companies can pin their operations.
Sure, it might be obvious to people that SDN is here to stay. But what exactly does that mean? And which SDN do I evaluate, purchase, and eventually deploy? Do I go with OpenFlow because ONF has convinced me that openness is the primary tenet? Do I Continue reading
Plexxi Pulse—Don’t Be Spooked by Big Data
We are getting into the Halloween spirit here at Plexxi—check out this Plexxi pumpkin carved by our talented marketing manager, Khoa Ma!
Jack-o-lanterns aside, we know the thought of navigating trends like the Internet of Things and Big Data can be frightening, especially if you are unsure of how to approach them. As these trends gain popularity and deployments increase, IT architects often worry about increased activity on already taxed infrastructures. Our own Mike Bushong is our resident expert on this topic and he penned an interesting blog post this week on networking’s atomic unit and “going small to scale up.” Creating smaller units of capacity makes the network easier to manage, and most importantly, scale. It’s definitely worth a read before heading out to trick-or-treat.
In this week’s PlexxiTube of the week, Dan Backman explains failure scenarios in case of hardware or software outages in a Plexxi pod design.
Network architect Brian Heder contributed an article to Network World this week on the importance and challenges of simplicity in computer network design. While I think Heder’s list is solid, I would add an additional obstacle to network simplicity: customization. Avoid making your network environment Continue reading
The Power of Correlated Visualization
I am sure our work environment is not all that different from many others. There are large whiteboards everywhere and you cannot find a meeting room that does not have circles, lines and squares drawn on them. Some of our favorite bloggers have written blogs about network drawing tools and aids. Probably not restricted to just networking folks, but we certainly love to visualize the things we do. Out of all the customers I have visited, the amount of them where one of us did not end up on a whiteboard can probably be counted on one hand.
It is not surprising that we are drawn to diagrams of the networks we have created. We build our network one device at a time, then use network links to connect the next and on we go until our network is complete. Which of course it never is. To track how we have connected all our devices we need diagrams. They tell us what devices we have, how they are attached to each other, how they are addressed and what protocols we have used to govern their connectivity. They are multi layered and the layers are semi independent.
I have previously said Continue reading
Conformity as an inhibitor to strategy
Early in life, we are all made acutely aware of the power of peer pressure. Most of us probably attribute it to a deep need for belonging. But what if that deep sense of belonging is less about social acceptance and more about how we are psychologically wired? In fact, the pursuit of conformity goes beyond mere social dynamics; it is rooted in how our cognitive selves.
While this plays out in very obvious ways for individuals, the dynamics actually hold true for organizations. And for companies, the stakes might be even higher.
A guy named Solomon
In the 1950s, an American psychologist named Solomon Asch ran through a series of experiments to test the effects of conformity on individuals. His studies have been published several times, but one test in particular gives a fascinating look into how we operate.
Asch took a number of participants and asked them very simple cognitive questions. To conduct the study, Asch brought participants into a room that had seven other people. However, these seven people were actually part of the study. The eight individuals were shown a card with a line on it, followed by a card with three lines on it. The Continue reading
Networking’s atomic unit: Going small to scale up
The major IT trends are all being driven by what can probably best be summarized as more. Some of the stats are actually fairly eye-popping:
- 40% of the world’s 7 billion people connected in 2014
- 3 devices per person by 2018
- Traffic will triple by 2018
- 100 hours of Youtube video are uploaded every minute
- Datacenter traffic alone will grow with a 25% CAGR
The point is not that things are growing, but that they are growing exceedingly fast. And trends like the Internet of Things and Big Data, along with the continued proliferation of media-heavy communications, are acting as further accelerant.
So how do we scale?
Taking a page out of the storage and compute play books
Storage and compute have gone through architectural changes to alleviate their initial limitations. While networking is not the same as storage or compute, there are interesting lessons to be learned. So what did they do?
The history lesson here is probably largely unnecessary, but the punch lines are fairly meaningful. From a storage perspective, the atomic unit shifted from the spinning disk down to a block. Ultimately, to scale up, what storage did was reduce the size of the useful atomic unit Continue reading
Plexxi Pulse—Challenging the Value of the Public Cloud + DemoFriday
Plexxi recently teamed up with Colovore, Piston Cloud Computing and King Star Computers to publish a whitepaper that challenges the assumption that the public cloud is inherently cheaper than the private cloud. Though the rapid speed of deployment and reduced capital expenditure has made services such as Amazon EC2 very attractive, the study shows that the rate of cost increase is often higher than that of a self-hosted private cloud solution. Brandon Butler recently reported on the paper’s findings for Network World.
We hope you were able to tune into DemoFriday today on SDNCentral. Our own Ed Henry and Nils Stewart did an excellent job of explaining how to construct Big Data fabrics that easily integrate with systems like OpenStack and Cloudera. We’ll share the full webinar once it’s live on SDNCentral’s site.
In this week’s PlexxiTube of the week, Dan Backman explains how Plexxi’s datacenter transport fabric can light up dark fiber between buildings on university campuses.
We’ve had a busy October! Check out what we’ve been up to on social media this month below. Have a great weekend!

Network Engineers, Pay Attention to Big Data
You have probably realized we are having a Big Data kind of week here at the Plexxi blog. And for good reason. The amount of development and change in this big bucket of applications we conveniently label “Big Data”, is astonishing.
Walking around at Hadoopworld in New York last week, I initially felt somewhat lost as a “networking guy”. But that feeling of “not belonging” is only superficial, the network has a tremendously important role in these applications. The challenge is that many “networking” folks don’t quite understand or realize that yet, but contrary to what I believed not too long ago, Big Data Application folks have a pretty good understanding of the role of the network in their overall application and its performance.
As an industry we have been talking about the increase in east-west traffic for quite a few years now. For your typical datacenter infrastructure today this is based on loosely coupled applications and semi-distributed storage. A web based application has many components that together make up the application we see as users. There are application load balancers, web server front ends, application back ends that in turn have databases for their data storage. And those databases Continue reading
Making the World a Better Place with Big Data
I spent last week at the Strata + Hadoop World Conference in New York City with 5000 other “big data” customers, vendors, and enthusiasts. In the last 6 months we’ve seen demand for a “big data” based network infrastructure really start to take off, and I’ve spent a lot of time recently trying to better understand the evolving market and technology landscape and use cases. I’m particularly interested in how network infrastructure can drive a better experience for users of big data applications, or networking/infrastructure teams that need to support these applications, but ultimately I want to know what do businesses get out of these investments in data, analytics, and infrastructure.
[On a related note, as part of our efforts to provide the best “Big Data Fabric” we recently brought on @networkn3rd (Ed Henry) to Plexxi to fully define our reference architecture. Ed will be demo’ing the first fruits of his labor this Friday on SDN’s Central’s Demo Friday - Register Here].
Hadoop World was a really great experience. As a relative newbie to Big Data, I have a lot to learn and this was a great place to soak up actual customer use cases. While there was certainly Continue reading
Outcome bias and the psychology that prevents sustained success
In psychology, there is a phenomenon called Outcome Bias, which basically means that we tend to judge the efficacy of a decision based primarily on how things turn out. After a decision is made, we rarely examine the conditions that existed at the time of the decision, choosing instead to evaluate performance based solely (or mostly) on whether the end result was positive or not.
But what happens as luck plays a role in outcomes? Did we actually make the best decision? Or was the result really a product of conditions outside of our control?
Understanding Outcome Bias
A relatively strong example of Outcome Bias can be found in the gambling world. Take poker, for instance. Many players will overplay the cards they are dealt. Imagine that you have four cards to a straight. There are two remaining cards to play. You might make bets that are statistically weak, but if the card you were looking for shows up, you will evaluate your own performance as strong for the hand. After all, you did win, right?
The challenge with Outcome Bias is that the fortuitous turn of events leads you play other hands in a similar way. Despite the fact Continue reading
SDN Market Sizing Redux
In April 2013, Plexxi teamed up with SDNCentral to take a look at how the SDN market might emerge. The original post along with supporting info graphic and written analysis can be found here. At a high level, the major takeaway was that we predicted that between 30 and 40 percent of the networking market would be influenced by SDN by 2018. At the time, this was BY FAR the most aggressive take on SDN. IDC had been projecting a little more than $3B by 2018, which would put their estimates somewhere around 5% of the overall networking spend.
So 18 months later, how do I feel about the analysis?
SDN spend is largely substitutive
In the original analysis, I made the point that SDN spend is not likely to be net-new dollars coming into the networking industry but rather a shift in dollars from traditional networking equipment to SDN-enabled equipment.
How’d I do? I’d say that this was spot on. Of course, this was the easiest of the predictions at the time. It is rare that dollars are created; they are usually shifted from somewhere else. Here, all I was really predicting was that the somewhere else was other Continue reading
Plexxi Pulse – This Week at Strata + Hadoop World
This week we joined thousands of thought leaders, analysts, vendors and end-users at the O’Reilly Strata + Hadoop World in New York. This event brings together the business and science of Big Data, allowing attendees to learn about emerging technologies through case studies and guest speakers. It’s been a busy week featuring excellent speakers from all over, including The New York Times and Cloudera. While we’re veterans of other industry events such as Interop and VMworld, we’re newbies here, so it’s exciting to experience this all for the first time. Judging by how things have gone so far, you can bet we’ll be back next year for more.
In this week’s PlexxiTube video of the week, Dan Backman highlights how Plexxi integrates with VMware.
Below are our best reads of the week – enjoy!
Data Center SDN growing 65% this year
In a recent article in Network World, Jim Duffy highlights the massive growth within the datacenter market – evidenced by a 65 percent growth in 2014 as reported by the Dell’Oro Group. Personally, I think it will be interesting to see if SDN survives as a separate feature out of the larger networking market. If the datacenter Continue reading
