Where the Cloud Touches Down: Simplifying Data Center Infrastructure Management

Thursday, July 25, 2013
10:00 AM PT/1:00 PM ET

In most data centers, DCIM rests on a shaky foundation of manual record keeping and scattered documentation. OpManager replaces data center documentation with a single repository for data, QRCodes for asset tracking, accurate 3D mapping of asset locations, and a configuration management database (CMDB). In this webcast, sponsored by ManageEngine, you will see how a real-world datacenter mapping stored in racktables gets imported into OpManager, which then provides a 3D visualization of where assets actually are. You'll also see how the QR Code generator helps you make the link between real assets and the monitoring world, and how the layered CMDB provides a single point of view for all your configuration data.

A Network Computing Webinar:
SDN First Steps

Thursday, August 8, 2013
11:00 AM PT / 2:00 PM ET

This webinar will help attendees understand the overall concept of SDN and its benefits, describe the different conceptual approaches to SDN, and examine the various technologies, both proprietary and open source, that are emerging. It will also help users decide whether SDN makes sense in their environment, and outline the first steps IT can take for testing SDN technologies.

OpenFlow Nascent But Making Solid Progress

March 12, 2012
The OpenFlow protocol for enabling software-defined networking has made progress, but to analyst Rohit Mehra, it’s still more of a concept than a reality. At last week's IDC Directions 2012 conference in San Jose, Calif., he tried to put the buzz about OpenFlow in perspective.

Cisco's Rumored Quasi-Proprietary SDN Strategy Irks Some, Surprises Few

February 15, 2012
Cisco Systems' hint that it may introduce software-defined networking (SDN) technology that would not be based on the OpenFlow protocol prompted complaints from competing networking vendors and the OpenFlow community that Cisco was making another vendor lock-in play by offering proprietary technology, rather than standards-based products. Industry analysts say it's to be expected that Cisco would go the proprietary route as a way to preserve its industry-leading market share, and rival vendors are pushing open standards because that's the only way they can eat into Cisco's share.

HP and Cisco Take Different Paths To SDN

February 03, 2012
News that Cisco Systems may release proprietary networking products implementing software-defined networking (SDN) technology, but not necessarily based on the emerging OpenFlow protocol, has executives at rival HP complaining about another Cisco vendor lock-in play. During a news event at HP Thursday, at which the company announced OpenFlow capability available for 16 HP networking product lines, executives were asked to comment on a news report from the Cisco Live event going on this week in London.

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.

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.

OpenFlow And Network Value

June 13, 2011
The announcement of OpenFlow has some people in networking optimistic that we are about to see a significant change in innovation and progress on network management. OpenFlow is a nascent networking specification that has three key elements: a software controller, the OpenFlow protocol and a client on the network device. It’s important to comprehend that all three elements combine to create a single coherent solution.

Interop Premieres New Technology; Everyone Wins

May 17, 2011
One of the coolest displays I saw at Interop was not in Start-up City nor in the Czech Republic zone. It wasn't the Lamborghini that Securent rolled onto the floor, nor was it the Barracuda Bus. It was the fiber backplane that HP brought out from its R&D facility and had running as a proof of concept, as well as the number of vendors that had products--nearly all proof of concepts--in the InteropNet Openflow lab. Staying awake is hard after sitting through the sixth top-of-rack switch of the day. Showcases like HP's and Openflow's should be an important part of any trade show because they remind us why what we do is cool and fun.
