Further Progress of Infineta

When I attended Network Field Day 3 (NFD3) in the Bay Area back in late March, the other delegates and I had the pleasure of receiving a presentation on Infineta Systems’ Data Mobility Switch (DMS), a WAN-optimization system built with merchant silicon and designed to serve as a high-performance data-center interconnect for applications such as multi-gigabit Business Continuity/Disaster Recovery (BCDR), cross-site virtualization, and other variations on what Infineta calls “Big Traffic,” a fast-moving sibling of Big Data.

Waiting on Part II

I wrote about Infineta and its DMS, as did some of the other delegates, including cardigan-clad fashionista Tony Bourke  and avowed Networking Nerd Tom Hollingsworth. Meanwhile, formerly hirsute Derick Winkworth, who goes by the handle of Cloud Toad, began a detailed two-part serialization on Infineta and its technology, but he seems to be taking longer to deliver the sequel than it took Francis Ford Coppola to bring us The Godfather: Part II.

Suffice it to say, Infineta got our attention with its market focus (data-center interconnect rather than branch acceleration) and its compelling technological approach to solving the problem.  I thought Winkworth made an astute point in noting that Infineta’s targeting of data-center interconnect means that the performance and results of its DMS can be assessed purely on the basis of statistical results rather than on human perceptions of application responsiveness.

Name that Tune 

Last week, Infineta’s Haseeb Budhani, the company’s chief product officer, gave me a update that coincided with the company’s announcement of FlowTune, a software QoS feature set for the DMS that is intended to deliver the performance guarantees required for applications such as high-speed replication and data backup.

Budhani used a medical analogy to explain why FlowTune is more effective than traditional solutions. FlowTune, he said, takes a preventive approach to network congestion occasioned by contentious application flows, treating the cause of the problem instead of responding to the symptoms.  So, whereas conventional approaches rely on packet drops to facilitate congestion recovery, FlowTune dynamically manages application-transmission rates through a multi-flow mechanism that allocates bandwidth credits according to QoS priorities that specify minimum and maximum performance thresholds.   As a result, Budhani says, the WAN is fully utilized.

Storage Giants

Last week, Infineta and NetApp jointly announced that the former has joined the NetApp Alliance Partner Program. In a blog post, Budhani says Infineta’s relationships with storage-market leaders EMC and NetApp validate his company’s unique capability to deliver “the scale needed by their customers to accelerate traffic running at multi-Gigabit speeds at any distance.”

A software update, FlowTune is available to all Infineta customers. Budhani says it’s already being  used by Time Warner.

Addressing SDN Burnout

In the universe of staccato text bursts that is Twitter, I have diagnosed a recent exhaustion of interest in software defined networking (SDN).

To a certain degree, the burnout is understandable. It is a relatively nascent space, generating more in the way of passionate sound and fury than in commercial substance. Some Twitter denizens with a networking bent have even questioned whether an SDN market — involving buyers as well as sellers — actually exists.

On that score, the pointed skepticism has been refuted. SDN vendors, including Nicira Networks and Big Switch Networks, increasingly are reporting sales and customer traction. What’s more, market-research firms have detected signs of commercial life. International Data Corporation (IDC), for example, has said the SDN market will be worth a modest $50 million this  year,  but that it will grow to $200 million in 2013 and to $2 billion by 2016. MarketsandMarkets estimates that the global SDN market will expand from $198 million in 2012 to $2.10 billion in 2017, representing a compound annual growth rate (CAGR) of 60.43% during that span.  I’m sure other market measurers will make their projections soon enough.

But just what are they counting? SDN isn’t a specific product category, like a switch; it’s an architectural model. In IDC’s case, the numbers include SDN-specific switching and routing as well as services and software (presumably including controllers and the applications that run on them). MarketsandMarkets is counting  SDN “switching, controllers, cloud virtualization applications, and network virtualization security solutions.”

Still, established networking vendors will argue that the SDN hype is out of proportion with on-the-ground reality. In that respect, they can cite recent numbers from Infonetics Research that estimate global revenue derived from sales of data-center network equipment — the market segment SDN is likely to make most headway during the next several years — was worth $2.2 billion in the first quarter of 2012. Those numbers include sales of Ethernet switches, application delivery controllers (ADCs), and WAN-optimization appliances.

This is where things get difficult and admittedly subjective. If we’re considering where the industry and customers stand today, then there’s no question that SDN gets more attention than it warrants. Most of us, including enterprise IT staff, do not wish to live in the past and don’t have the luxury of looking too far into the future.

That said, some people have the job of looking ahead and trying to figure out how the future will be different from the present. In the context of SDN, those constituencies would include the aforementioned market researchers as well as venture capitalists, strategic planners, and technology visionaries. I would also include in this class industry executives at established and emerging vendors, both those directly involved in networking technologies and those that interact with networking infrastructure in areas such as virtualization and data-center management and orchestration.

For these individuals, SDN is more than a sensationalized will-o’-the-wisp.  It’s coming. The only question is when, and getting that timing right will be tremendously important.

I suppose my point here is that some can afford to be dismissive of SDN, but others definitely cannot and should not. Is interest in SDN overdone? That’s subjective, and therefore it’s your call. I, for one, will continue to pay close attention to developments in a realm that is proving refreshingly dynamic, both technologically and as an emerging market.
