Although media briefings took place yesterday in New York, HP officially announced new networking products and services this morning based on its HP FlexNetwork Architecture.
Bethany Mayer, senior VP and general manager of HP Networking, launched proceedings yesterday, explaining that changing and growing requirements, including a shift toward server-to-server traffic (“east-west” traffic flows driven by inexorable virtualization) and the need for greater bandwidth, are overwhelming today’s networks. Datacenter networks aren’t keeping pace, bandwidth capacity in branch offices isn’t where it needs to be, there is limited support for third-party virtualized appliances, and networks are straining to accommodate the proliferation of mobile devices.
Quoting numbers from the Dell’Oro Group, Mayer said HP continues to take market share from Cisco in switching, with HP gaining share of about 3.8 percent and Cisco dropping about 6.5 percent. What’s more, Mayer cited data from analyst firm Robert W. Baird. indicating that 75 percent of enterprise-network purchase discussions involve HP. Apparently Baird also found that HP is influencing terms or winning deals about 33 percent of the time.
The Big Picture
Saar Gillai, vice president of HP’s Advanced Technology Group and CTO of HP Networking, followed with a presentation on HP Networking’s vision. Major trends he cited are virtualization, cloud computing, consumerization of IT, mobility, and unified communications. Challenges that accompany these trends include complexity, management, security, time to service, and cost.
In summary, Gillai said that the networks installed at customer sites today just weren’t designed to address the challenges they’re facing. To reinforce that point, Gillai provided a brief history of enterprise application delivery that took us from the 60s, when we had mainframes, through the client-server era and the Web-based applications of the 90s through to today’s burgeoning cloud environments.
He explained that enterprise networks have evolved along with their application delivery models. Before, they were relatively static (serving employees onsite, for the most part), with well-defined perimeters and applications that were limited qualitatively and quantitatively. Today, though, enterprise networks must accommodate not only connected employees, but also connected customers, partners, contractors, and suppliers. The perimeter is fragmented, the network distributed, the applications mobile (even in the data center with virtualization), client devices (such as smartphones and tablets) proliferating, and wireless LANs, the public cloud and the Internet also prominently in the picture.
Connecting Users to Services
What’s the right approach for networks to take? Gillai says HP is advancing toward delivering networks that focus on connecting users to the services they need rather than on managing infrastructure. HP’s vision of enterprise-network architecture conceives of a pool of virtualized resources where managing and provisioning are done. This network has a top layer of management/provisioning, a layer below inhabited by a control plane, and then a layer below that one comprising physical network infrastructure. In that regard, Gillai drew an analogy with server virtualization, with the control plane functioning as an abstraction layer.
With talk of a management layer sitting above a control plane that rides atop physical infrastructure, the HP vision seems strikingly similar to the defining principles of software-defined networking as realized through the OpenFlow protocol.
OpenFlow: It’s About the Applications
On OpenFlow, however, Gillai was guardedly optimistic, if not a little ambiguous. Although noting that HP has been an early proponent of OpenFlow and that the company sees promise in the technology, Gillai said the critical factor to OpenFlow’s success will be determined by the applications that run on it. HP is interested in those applications, but is less interested in the OpenFlow controller, which it does not see as a point of differentiation.
Gillai is of the opinion that the OpenFlow hype has moved considerably ahead of its current reality. He said OpenFlow, as a specific means of enabling software-defined networking, is evolutionary as opposed to revolutionary. He also said considerable work remains to be done before OpenFlow will be suitable for the enterprise market. Among the issues that need to be resolved, according to Gillai, is support for IPv6 and the “routing problem” of having a number of controllers communicate with each other.
On the Open Networking Foundation (ONF), the private non-profit organization whose first goal is to create a switching ecosystem to support the OpenFlow interface, Gillai suggested that the founding and board members — comprising Deutsche Telekom, Google, Microsoft, Facebook, Verizon, and Yahoo — have a clear vision of what they want OpenFlow to achieve.
“If the network could become programmable, their life will be great,” Gillai said of the ONF founders, all of whom are service providers with vast data centers.
Despite Gillai’s reservations about OpenFlow hype, he indicated that he believes “interesting applications” for it should begin emerging within the next 12 to 24 months. He also said that it “would not be big surprise” if HP were to leverage OpenFlow for forthcoming control-plane technology.
ToR Switch for the Data Center
As for the products and services announced, let’s begin in the data center, seen by all the major networking vendors as a lucrative growth market as well as venue for increasingly intense competition.
HP FlexFabric solutions for the data center include the new 10-GbE HP 5900 top-of-rack (ToR) switch and the updated HP 12500 switch series.
HP says the new HP 5900 series of 10-GbE ToR switches provides up to 300 percent greater network scalability while reducing the the number of logical devices in the server access layer by 50 percent, thereby decreasing total cost of ownership by 50 percent.
Lead Time and Changes to Product Naming
The switch is powered by the HP Intelligent Resilient Framework (IRF), which allows four HP 5900 switches to be virtualized so that they can operate as a single switch. The HP 5900 top-of-rack switch series is expected to be available in Q1 2012 in the United States with a starting list price of $38,000.
It bears noting that HP typically refrains from announcing switches this far ahead of release data. That it has announced the HP 5900 ToR switch six months before it will ship would appear to suggest both that customers are clamoring for a ToR switch and also that competitors have been exploiting the absence of such a switch in HP’s product portfolio. Although the 5900 isn’t ready to ship today, HP wants the world to know it’s coming soon.
HP says its HP 12500 switch series benefits from improved network resiliency and performance as a result of the addition of the updated HP IRF technology. The switch provides full IPv6 support, and HP says it doubles throughput and reduces network recovery time by more than 500 times. The HP 10500 campus core switch is available now worldwide starting at $38,000.
You might have noticed, incidentally, something different about the naming convention associated with new HP switches. HP has decided that, as of new, its networking products will just have numbers rather than alphabetical prefixes followed by numbers. This has been done to simplify matters, for HP and for its customers.
On the campus front, new HP FlexCampus offerings include the HP 3800 stackable switches, which HP says provide up to 450 percent higher performance. HP also is offering a new reference architecture for campus environments that unifies wired and wireless networks to support mobility and high-bandwidth multimedia applications. The HP 3800 line of switches is available now worldwide starting at $4,969.
Although HP did not say it, at least one of its primary competitors has cited a lack of HP reference architectures for customers, particularly for campus environments. HP clearly is responding.
HP also unveiled virtualized services modules for the HP 5400zl and 8200zl switches, which it claims are the first in the industry to converge blade servers at the branch into a network infrastructure capable of hosting multiple applications and services. The company claims its HP Advanced Services zl Module with VMware vSphere 5 and HP Advanced Services zl Module with Citrix XenServer deliver a 57-percent cut in power consumption and a 43-percent reduction in space relative to competing products. Available now worldwide, the vSphere HP Advanced Series zl Module with VMware vSphere 5 (including support and subscription, 8GB of RAM) starts at $5,299. The HP Advanced Services zl Module with Citrix XenServer (including support and subscription, 4GB of RAM) starts at $4,499.
Emphasis on Simplicity and Evolution
HP also rolled out HP FlexManagement with integrated mobile network access control (NAC) in HP Intelligent Management Center (IMV) 5.1 to streamline enterprise access for mobile devices and to protect against mobile-application threats. HP Intelligent Management Center 5.1 is expected to be available in Q1 2012 with a list price of $6,995.
Also introduced are new services to facilitate migration to IPv6 and new financing to allow HP’s U.S-based channel partners to lease HP Networking products as demonstration equipment.
Key words associated with this slate of HP Networking announcements were “evolutionary” and “simplification.” As the substance and tone of the announcements suggest, HP Networking is responding to its customers and partners — and also to its competitors — closing gaps in its portfolio and looking to position itself to achieve further market-share gains.
