Intel Makes Exascale Bet on InfinBand-Based Supercomputing
January 25, 2012
Intel, which played a key role in the creation of the InfiniBand high-speed networking standard a decade ago, has come full circle and bought the IB assets of Qlogic, one of the two remaining companies still actively pushing the technology. While $125 million is chump change for a company that netted $3.4 billion in profits last quarter, Intel says the acquisition will enhance its networking portfolio and provide scalable high-performance computing (HPC) fabric technology as well as support the company's vision of innovating on fabric architectures to achieve ExaFLOP/s performance by 2018. At a hundred times faster than today's fastest supercomputers, it's an aggressive move, seeking to accelerate performance to a quintillion computer operations per second.IBM And NEC Leverage OpenFlow For High-Performance Networking
January 24, 2012
IBM and NEC are collaborating on high-performance OpenFlow deployments. OpenFlow, developed at Stanford University, has enjoyed acceptance in university networks because an OpenFlow network can run alongside the campus production network without impacting it. In 2011, OpenFlow broke out of its education niche into the mainstream with announcements from Big Switch, Fulcrum and NEC. IBM's and NEC's announcement is a proof point that OpenFlow has a role in enterprise IT and can be used in high-performance applications.Big Switch Networks Intros Open-Source OpenFlow Controller
January 17, 2012
Big Switch Networks, a new vendor in the nascent but growing field of OpenFlow-based networking, has introduced an open source controller for companies that want to build applications on top of the controller in an environment where the network intelligence is in the software-based controller rather than in the physical hardware of routers and switches. Big Switch, which also has a commercial controller offering in beta release, said it is offering the open source controller, called Floodlight, to stimulate development on the OpenFlow protocol.As IT Demands More Of Networks, Expect HP-Cisco Rivalry To Intensify
January 03, 2012
Across IT, many observers have identified three broad trends going forward: mobility, cloud computing and the consumerization of IT. When it comes to networking, these trends are expected to drive demand for more bandwidth capacity and, increasingly, wireless network architecture. In addition, 2012 is expected to see a continuation of the intense rivalry between industry leaders Cisco Systems and HP, as the latter tries to chip away market share from the former.2011 Was An Awesome Year For Networking
December 28, 2011
After about eight or nine years of networking innovation stagnation, the number of new innovations starting in 2010 and exploding in 2011 is astounding. Speed and feeds are increasing, but the exciting work in 2011 occurred in new technologies to support initiatives such as cloud computing, storage and data convergence, as well as migrating to IPv6. Here are the highlights.New And Notable On Network Computing
November 16, 2011
It's been a busy year for our IT staff. We've moved to a new platform that is more stable and faster. We have a new commenting system in place, and we are adding more kinds of content. Network Computing Pro, once a subscription service, is now free (registration required). And we'll have more changes in the coming months. All of these changes have been part of a long process, but one that lets us bring you more and better news, views and actionable information. Now I'd like to hear from you. What do you want to see? What can we do better? We'll try to incorporate your changes.A Brief Introduction To OpenFlow
November 14, 2011
OpenFlow is a specification now managed by the Open Networking Foundation, which defines the functions and protocols used to centrally manage switches via a centralized controller.Juniper Offers OpenFlow Source Code To Developers
October 27, 2011
Juniper Networks is jumping on the OpenFlow bandwagon, putting the OpenFlow source code in the Junos SDK. The company says that the OpenFlow application works within the SDK to change the control plane to create more dynamic network programmability for custom applications that run on top of the Junos operating system.Cisco Fellow On Possible Threat To Cisco Of OpenFlow: 'Folks Get This'
October 21, 2011
Software-defined networking, an emerging technology that moves intelligence out of switches and routers to a software controller, is seen as a potential threat to networking vendors, particularly market leader Cisco Systems. A Cisco fellow speaking at an SDN conference this week said the company is aware of the situation and is preparing to deal with it.Cisco Broadens Data Center Portfolio
October 18, 2011
With spending on data center hardware recovering and expected to grow to $98.9 billion this year and approach $130 billion by 2015, Cisco is expanding its data center portfolio. The networking giant is introducing second-generation capabilities for the Nexus 7000 family and Cisco FabricPath support for the Nexus 5500 switch; new switches with sub-microsecond latency to the Nexus 3000 ultra-low-latency switching family; and a virtualized version of its Adaptive Security Appliance to deliver consistent security for virtualized and cloud environments.
