There’s a lot of talk in the switching space about both price (driven by bare metal switching) and capability (spawned from the rise of SDN). Around these topics, there is a lot of conjecture about how the competitive landscape will play out. Some argue about margins and business model...
It means you can't use "network" protocols to make intelligent decisions about applications any more. Back in 2000 (or 2001, I forget exactly), I got to test a variety of bandwidth management appliances. Oh, they were the bomb back then - able to identify (and classify) applications b...
If you’ve been keeping up with Plexxi, you know we’re proud of our roots on the East Coast. However, we have exciting news this week for the West Coast contingent of our team. Our San Francisco team has just moved to into the communal office space called WeWork (the SOMA one, not the G...
How many of you actually fill out the registration cards that come with your kid's toys? Anyone? Anyone? Bueller? Bueller? That's what I thought. Me neither. Not as a parent and certainly not as an adult. After all, they were just going to use it for marketing, right? Fast forwa...
In reviewing some opportunities for Plexxi this week, I was reminded that we have made things very hard on ourselves. Through no one’s fault but our own we have created monsters of networks that are impossible to maintain, debug, diagnose and understand. I have been lucky in my career...
London, 1 May 2014 - The Kenton Group is to offer 100G networks with SDN / NFV to its European and Middle East customer base following a landmark agreement with Cyan (NYSE: CYNI), a leading provider of software-defined networking (SDN) and packet-optical transport solutions (P-OTP) for...
There’s a running meme in networking that has caught a lot of momentum with SDN: abstraction. Just about every vendor these days has bold ambitions to abstract out the complexity. There are APIs, abstraction layers, and architectural shims that all aim to hide complexity from the user....
AppDynamics is excited to unveil details behind our new Application Intelligence Platform which is the technology foundation for the AppDynamics portfolio of performance monitoring, automation and analytics solutions (transaction analytics was also announced today). Today’s software d...
Targeting Cloud-enabled Data Centers with Big Data Demands Milpitas, CA and Pittsburgh - April 29, 2014 - Amplidata, a leader in object-based software defined storage, and Avere Systems, a leading provider of enterprise storage for cloud-enabled data centers, today announced a partners...
How many different network protocols can you name? There are, of course, a set of staples just about everyone knows: IP, ARP, VLAN, TCP, UDP, DNS, HTTP, SSL, TLS, SMTP, FTP, SMB, CIFS, 802.1q, 802.1ad. Then there are recent additions like VXLAN, NVGRE, SPDY. But we could fill post ...
Over the past year, Plexxi has not focused on the research and education markets. Although the roots of SDN come from the education (i.e. university) market, we believed that Plexxi’s photonic ethernet switches would find faster adoption in the cloud, IaaS, SaaS and big data markets. ...
This week, Gartner analysts Andrew Lerner, Tim Zimmerman and Joe Skorupa named Plexxi one of four “Cool” Vendors in Enterprise Communications. In Lerner’s own words, cool is defined as “the ability to help customers address challenges in new and innovative ways. These challenges could ...
Way back in the early days of the Internet scalability was an issue (the more things change...). One of the answers to this problem was to scale out web servers using a fairly well-proven concept called load balancing. Simply put, distribute the load across web servers to make sure eve...
Enterprise SSHD and Flash SSD Part of an Enterprise Tiered Storage Strategy By Greg Schulz Enterprise SSHD and Flash SSD Part of an Enterprise Tiered Storage Strategy The question to ask yourself is not if flash Solid State Device (SSD) technologies are in your future. Ins...
From a cost perspective, the networking dialogue is dominated by CapEx. Acquisition costs for new networking gear have historically been tied to hardware, and despite the relatively recent rise of bare metal switching, networking hardware remains a high-stakes business. But SDN is chan...
Take a moment to consider the things we put up with on a daily basis because they have been understood and accepted as the status quo. Perhaps the old adage, “better the devil you know than the devil you don’t,” rings no truer than for traditional on-premise data storage systems. Sure,...
Over the past few years, the SaaS community has gained a solid understanding of SaaS financial metrics, as well as many of the operational principles required to achieve them. However, there has always been an obvious gap between what happens on the top line and what happens on the gro...
We've talked before about the bifurcation of the network, which is driven as much by the evolution of network services from "nice to have" to "critical" as it is by emerging architectures. The demarcation line in the network stack has traditionally been - and remains - between layers 3...
Have you ever been in a position where the right answer is immediately obvious to you and yet you cannot get the other party to come around? While we tend to ascribe poor outcomes to the other party’s incompetence, there is actually a very real psychological phenomenon behind the dynam...
Integra recognized for innovation in Software Defined NetworkingREDWOOD CITY, Calif - April 22, 2014 - For the second year running Openwave Mobility, a software innovator enabling operators to manage and monetize mobile data, has won the Excellence in SDN Award for Integra - the indust...
Like moving to IPv6, simply picking up your existing network architecture and moving it to a completely new one is not going to happen overnight. There will undoubtedly still be "traditional" networks hanging around even when SDN adoption is considered mainstream and fully mature. That...
[This post is penned by Plexxi executive Bill Koss] Two months ago I read an interesting blog post by Greg Ferro titled “Cheap Network Equipment Makes a Better Data Centre.”  At Plexxi, I am the person who leads our sales team and I found the post interesting because I think there is a...
Next week our own Mike Bushong heads to the Software Defined Data Center Symposium, an event organized by our friends over at Tech Field Day. The symposium will take place at the Santa Clara Convention Center on Tuesday, April 22 from 8am to 5pm. Along with other industry influencers, ...
Earlier this week, Ethan Banks wrote a very nice article about Mellanox’s dual spine and leaf network in support of a large amount 10GbE access ports. After describing the scaled up network design, he reviews 8 observations about the design, not to point out good or bad, but merely to ...
Last week was a crazy week for information security. That's probably also the understatement of the year. With the public exposure of Heartbleed, everyone was talking about what to do and how to do it to help customers and the Internet, in general, deal with the ramifications of such a...

In order to manage today’s highly dynamic application environments, many organisations turn to their logging system for answers – but reliance on these systems may be having an undesired impact on the applications themselves. The vast majority of organisations use some sort of logging...
One of the most powerful aspects of the Internet of Things is the process of synthesis it achieves; it provides a mental model for people to associate and relate a number of different technologies under one umbrella concept and trend. Therefore one early quick win is a simple taxonomy...
OpenStack. OpenDaylight. SDN. Cloud. It's all about abstraction, about APIs and "software-defined" (which really means software-controlled, but this is neither the time or place to get into that debate). It's about jailbreaking the network. Enabling access to features and functionalit...
There are things we tend to take for granted in our everyday lives. We have certain expectations that don’t even have to be spoken, they’re just a given. If you walk into a room and turn on the light switch, the lights will go on, it’s assumed. If you turn the water faucet on, water wi...
Not too long ago, it took even the most successful entrepreneurs several centuries or at least decades to reach a valuation of a billion and thus become a member of the exclusive Billionaire Boys Club*. Families like the Rothschilds, the Waltons or the Brenninkmeijers have indeed built...
Despite claims that there exists (or will, look out!) a mythical "god box" for the enterprise data center, capable of performing every data center function imaginable, it remains, well, mythical. Efforts to effectively secure the data center and the applications it delivers therefore r...
That networking gear is expensive is not really a new phenomenon. SDN and bare metal switching have kicked the industry dialogue about cost up a notch, but this has obviously been a focal point for networking buyers for years. And even though things like merchant silicon and software c...
University aims to dramatically increase network performance and resilience to support 25,000 students across four campuses through infrastructure upgradeBracknell, UK - 11 April, 2014: The University of Westminster, one of London's largest and most respected higher education instituti...
We love analogies. No matter what the topic, analogies are a great way to explain something in a different context to make a specific point with a frame of reference that may be more familiar to those we are making a point to. There is one that seems to come back over and over again in...
Nick Lippis, who writes the eponymously named Lippis Report, had a fascinating report on the differences between enterprise and service provider environments with respect to network virtualization. He observes, through a survey of the ONUG (Open Networking User Group) membership, t...
In any space, there is a very small vocal minority. Most people lack the time, interest, or even confidence to say what they think in public. So we are left with a vocal few who drive the conversation. In networking, the vocal minority consists mainly of the vanguards for change. For t...
There’s a reason the superlative term “broadcast quality” is the measuring stick and euphemism for “highest possible video quality” — [...]
