How Data Center Networking is Evolving to Meet the Demands of Virtualization

Tuesday, November 8th, 2011

Ethernet switching is in a sea change, and server virtualization is a big part of the reason why. Gartner recently published a new competitive landscape for data center Ethernet switches. In that report, titled “Competitive Landscape: Data Center Ethernet Switches, Worldwide, 2011,” Gartner made several interesting comments about this evolving space and how trends such as virtualization and cloud computing change data center Ethernet switch requirements.

This report includes Xsigo in the data center Ethernet switch category, adding Xsigo to the “Data Center Network Specialist” group, along with Brocade, Extreme Networks, and Juniper Systems.

The definition of this group is vendors that “depend on their dedicated focus and specialization in networking to innovate and meet the fast-evolving needs of customers.”

The words “fast evolving” nicely sum up what we see happening.

In the past, there was no clear distinction between the switches found in a data center and those used elsewhere in the organization.

But this is now changing. Virtualization changes the game, not just for the way we run applications on servers, but also for the way those applications interact with all of the other data center resources.

For that reason, the data center Ethernet switch is taking on a new look. Gartner characterized this ongoing transition as “an important step in the evolution from box-centric, data-center-optimized Ethernet solutions to a fabric-based approach for large data center and cloud infrastructure.” 

In one sense, you could say that actually very little has changed. Applications still need access to specific resources: networks, storage, and the devices that surround them, such as load balancers, security devices, and other appliances. And the applications still require sufficient bandwidth to ensure that performance meets the objectives.

The difference with virtualization is this: those exact same requirements must now be met in a dynamic world, where multiple applications could reside on any server, not just one application on a dedicated device. This is a big change.

Here are three examples of the issues this creates for the switching infrastructure:

-          The “East-West” problem: In the old days, most data centers were laid out in nice, orderly tiers, allowing data to flow in predictable paths. But with virtualization, applications can run anywhere. This creates messy server-to-server data paths where data must negotiate multiple layers of infrastructure to reach its destination.  The resulting latencies, bottlenecks and general bad behavior are called the “East-West Problem.” If we’re going virtualize more, and make data centers truly resemble a cloud, this must be addressed.

-          Exponential performance demands: Virtualized servers demand a lot more I/O bandwidth than bare metal servers do. At Xsigo, we’ve seen this firsthand. Over the past four years we have upgraded the performance of our server interconnect from 10Gb, to 20Gb, and then to 40Gb. While the rest of the industry has experienced a somewhat leisurely transition from 1Gb to 10Gb connections, our customers (most of whom are hard-core virtualization users) have hungrily jumped to the highest available speed. They have simply found that virtualization works better with more bandwidth.

-          VLAN Exhaustion: VLANs did a great job of addressing the problem they were created to solve. But when it comes to creating large numbers of isolated interconnects within an agile data center, they don’t scale well. You can run out of VLANs. Or they can become a management nightmare to administer. Eliminating this problem — while providing the needed isolated connections — is a challenge that must be overcome.

Gartner stated in the report that, “data center switching is a fast-evolving market with a different problem set and several new technologies likely to disrupt legacies.”

At Xsigo, we see this happening already.

The new Xsigo Server Fabric addresses the needs of scalable, high-performance Ethernet switching with virtual I/O capabilities that are ideally suited to the needs of a dynamic data center.

The Xsigo approach is different from the traditional network switch, yet it’s being deployed in support of very traditional, mainstream applications within large organizations.

And in that way, it meets the most important requirement of all: to provide a seamless, non-disruptive path forward towards a more efficient, lower-cost data center.

Why Following the Cisco Party Line Could be Bad for Your Future

Monday, July 11th, 2011

Is it really true that “no one ever got fired for buying Cisco”? Maybe, but following their party line is no sure recipe for getting promoted either. Read Cisco’s comments below and you’ll see the truth: if you blindly follow their lead, you could hurt your company and ultimately hurt yourself.

Consider these statements recently made by a sales manager on a Cisco sales conference call:

“If Xsigo’s in [your customer] and the server guys are managing it, you need to talk to that network team and get them aware of the situation, right, because they are losing control.”

Think about this. Cisco is advising customers that the first priority should be maintaining the status quo rather than comparing solution merits.

Later in the call, the manager underscored this point by stating, “…we’re going to be more expensive, right, so bring that up up front.”

In other words, “don’t seek the better solution and don’t worry about price.”

This is like a car dealer saying, “you can buy a better car, but you can’t pay more.” It kind of has a catchy ring, but the logic is all wrong.

A monopoly in action

Such distorted reasoning becomes all too predictable when you acknowledge that Cisco behaves as a monopolist. Analysts estimate that Cisco has a 72% share of the networking market, well beyond the 50% share that Forbes magazine sets as a “monopolist” threshold. With that share, Cisco can exercise the traditional monopoly powers: stifle innovation, control prices, and excise would-be competitors.

In their position, the customer’s best interests become secondary to the greater goal of maintaining market control.

Non-monopoly companies don’t behave this way. They compete with other companies, vying to offer you the better solution.  A monopolist, on the other hand, competes with the more fundamental market forces that would create better technologies. Suppressing competition is a lot easier than surpassing it.

Cisco’s objective is to make the networking component of the data center more dominant, not less. Preserve the existing approach, even if alternative solutions could result in better economies.

We’ve seen this movie many times before

History has so many sorry examples of companies exhibiting the same behavior. Microsoft fixated on the operating system and missed multiple industry transitions: to the web, to search, and again to software as a service.

For another example, look at server virtualization. This revolution began not with Microsoft, Compaq or HP, any of whom could have led it. After all, virtualization technology was well known, having been established back in the 1960’s. But their interests were to sell more sockets and systems, not less. So the answer emerged from an outsider, VMware, who had no vested interest in maintaining the status quo.

What’s at stake: Your company and your career

Why should you care about all this? This matters because your company wins when you innovate. You help get products to market faster, develop better customer relationships, and become more profitable. And when the company wins, so do you, the innovator. You have to. You hold the keys to the newer, faster machine.

Blindly following Cisco’s lead – or blindly following anybody’s lead – makes both you and your company followers, and puts you on the fast track to being outsourced.

If your value comes from doing what Cisco tells you to do, well anyone can do that.  On the other hand, look for example at what the new breed hosting and cloud service providers like Bluelock and dinCloud are doing by pursuing innovation.

Gartner summed this up pretty succinctly in this article: “Network architects and CIOs who don’t re-evaluate long-held incumbent vendor decisions (with any vendor) on a periodic basis are not living up to fiduciary responsibilities to their organization.”

The bottom line is that a single vendor track will always be more expensive and provide you with less innovation. Is this really the choice you want to knowingly make?

How eBay/StubHub Saved 50% with Xsigo vs. Cisco

Thursday, June 2nd, 2011

StubHub, a division of eBay, reported savings of 50% using Xsigo. And got what they believe is a better solution than what Cisco was offering. This is straight from an article today on Bloomberg.

Here are some excerpts from the article:

“When StubHub Inc. executive Robert Capps oversaw the building of a new data center, he shunned Cisco Systems Inc.”

“‘Cisco wasn’t serving our needs,’ Capps said. ‘They were not innovating in the areas of data-center operations that we needed innovation.”

“For years, Cisco has benefited from the impression that its products are a safe bet, said StubHub’s Capps, who switched to gear from Arista Networks Inc., Xsigo Systems Inc. and Mellanox Technologies Ltd. to outfit his data center.”

StubHub did the research in building out their cloud and found what they considered to be the most flexible, cost effective solution. And it was not from Cisco.

Collateral Damage in the FCoE Wars

Saturday, May 21st, 2011

Has interoperability become collateral damage in the infrastructure convergence debate? Cisco talks “open,” but when you go to implement their convergence solutions, some find there’s significant retrofit. This unfortunate surprise creates a bad perception, and may be painting the whole convergence landscape with the same negative brush.

Cisco’s talk of “open” is actually a “wolf in sheep’s clothing” approach. According to former Cisco exec Doug Gourlay, Cisco’s playbook was always to drive retrofit.

Doug stated (in this article), “The entire goal of data center bridging, Fibre Channel over Ethernet and TRILL, when first conceived under Data Center Ethernet, was to churn the install base—to create a reason to get people off the Catalyst 6500 and upgrade to the next generation of products.” Ouch.

To most people “open” means  “interoperable with the gear I have.” It does not mean, “interoperable with the gear you want to sell me.” That’s a very important distinction. In a survey of IT managers, Information Week found that “adherence to industry standards” was the most important attribute in data center networking features.

Convergence can be risk free

Convergence solutions can be easily integrated into your data center when they truly are standards-based.

Xsigo’s approach is to use standard components. Standard silicon. Standard cards in the servers.

With Xsigo, the I/O ports on the servers themselves simply become a smaller number of ports on the top-of-rack I/O Director. Nothing else changes.

NICs and HBAs appear in servers as they always have. FC and Ethernet ports appear to the LAN and SAN as they always have (there are just fewer of them). They are conventional Qlogic and Broadcom silicon, so interoperability is built in.

Arron Branham, IT manager at Bluelock, a cloud service provider, installed Xsigo into an existing data center, so interoperability was a key metric for him. He stated that Xsigo was “disappointingly easy to install and configure.” (See the case study here.)

Convergence reaps huge benefits. It gives you a simpler infrastructure and the flexibility to change on-the-fly. It also gives you a 70% reduction in core switch ports. Which, by the way, explains Cisco’s “wolf in sheep’s clothing” approach. If your core business is core switch ports, you’d better find a way to sell a few more of them along the way to selling less of them.

But don’t get confused. That’s a part of the Cisco story. It’s not a part of the convergence story.

HP Takes a Stand for Lock-In

Friday, March 18th, 2011

HP this week announced a decision in favor of vendor lock-in. They halted the anticipated introduction of a rack-based VirtualConnect product. With this one decision, they messaged their intention to own the entire stack and to limit their customer’s options to configure best of breed solutions.

A rack-based VirtualConnect would have allowed customers to configure I/O on both rack servers and blade servers within a single management environment.

And it may even have also allowed customers to configure I/O on mixed-vendor rack servers. But we’ll never know.

While the decision is distinctly not customer-friendly, the reasons behind it are pretty easy to deduce. VirtualConnect has reportedly been a financial winner for HP. It produces terrific margins and it provides a strong competitive advantage for HP’s blade systems vs. other blade systems.

And perhaps best of all, it reinforces vendor lock-in.

VirtualConnect ONLY works with HP blades. The implications of that are huge. The whole point of virtual I/O is to unify management — you achieve the greatest value when you can leverage the tools and techniques across more and more servers. But HP is saying you can do that only if you buy more of their own blades.

Xsigo on the other hand works with every x86 system out there. Every x86 vendor sells the mezzanine cards, blade switches, and PCI host adapters needed to connect Xsigo. You can buy and configure a system – either blade or rack – from your favorite vendor and get virtual I/O functionality.

So the choice just became even more clear. With HP’s VirtualConnect, you can buy any server you want… as long as it’s HP blades. Xsigo gives you an open management environment that lets you leverage the capabilities of virtual I/O across all your servers, both now and in the future.

Cisco Takes Another Swipe at Xsigo

Thursday, February 17th, 2011

Cisco struck again today. On a webinar this morning they spent 40 minutes arguing their competitive position vs. Xsigo.

The fact that Cisco would host a webinar to target one specific competitor seems pretty amazing in itself. And to then consume 40 minutes of valuable airtime to make their case is also amazing.

But that’s what they did.

As with their previous FUD document (read that document here), their facts were a bit mangled.

And again they completely ignored the fact that Xsigo has an Ethernet fabric product and an InfiniBand fabric product. (Well, in fairness, if I had created an entirely new technology, FCoE, to accomplish what Xsigo does with standard Ethernet, I wouldn’t highlight that either…)

So, for your convenience we’ve repeated all of their points below, along with our response.









The Inside Story: What Cisco says About Xsigo

Tuesday, December 14th, 2010

In this era of WikiLeaks, it should be no surprise that information  gets out eventually. And that’s what’s happened here.

See also, “Five Ways to Save Big on Your Next Cisco Purchase.”

Cisco generated the document below to educate their team on how to compete against Xsigo. One thing led to another, and now thanks to an overseas listening post, it’s in the open. It’s posted in its entirety here. We’ve interspersed some “Xsigo response” slides to illuminate the positive points they raise and to correct some of the disinformation.

Here’s one surprise: the positive points they raise actually outnumber the “negative.”

And when you exclude the “negative” points that are incorrect, you’re left with pretty much just one punch line: Xsigo is not as big as Cisco.

Cisco can clearly leverage their size in numerous ways. Tasking employees to generate and disseminate propaganda such as this is one. And there are many other market levers where their near monopoly status can help, such as bundling gear.

But a fundamentally better, more open, easier to use solution has market power as well.

Gartner reports that 82% of data center managers now factor data center convergence into their 3-year plans. So this is an important space. To fill that need, you have a choice between two very different solutions. When the best the competition can really say is, “we’re bigger,” it helps to further illuminate your options.
