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.

Coho Applies SDN To Scale-Out Storage

October 28, 2013
Startup Coho Data uses an integrated OpenFlow controller to reduce the latency associated with traditional scale-out storage designs.

OpenFlow Vs. Fabrics

October 08, 2013
Network fabrics can optimize hardware performance in the data center, but OpenFlow can provide many of the same benefits while also integrating better with tunnels.

10 Software-Defined Networking Architectures

September 27, 2013
Software-defined networking is a hot topic for debate in the industry. Experts argue about the best way to implement it, the ways it might affect network engineers and administrators, and how it might disrupt the traditional power structure in the networking industry. While there are a lot of opinions about this emerging technology, there's one inescapable fact: SDN has brought new attention and innovation to the network. To get a view into the various approaches to SDN, we asked 10 vendors to supply images and short descriptions of their SDN technology. While there's some marketing fluff in some of the write-ups, the images provide a window into the wide range of technical approaches to SDN.

SDN, Overlays and Interior Decorating

July 15, 2013
Redesigning your network with SDN is kind of like interior decorating. Overlays let you paper over your existing network, while OpenFlow might require some rebuilding.

Inside Google's Software-Defined Network

May 14, 2013
Google shared details on its production use of OpenFlow in its SDN network at this spring's Open Networking Summit.

VMware Adds Interoperability With Ubuntu OpenStack Cloud

April 19, 2013

VMware has contributed plug-ins to the OpenStack Project that guarantees the project's networking platform will recognize and work with virtual machines running under VMware's vSphere management environment and VMware's Nicira Network Virtualization Platform.

VMware acquired startup Nicira last July for $1.26 billion and has made its NVP the basis of future virtualized networking in what it terms "the software-defined data center." The Network Virtualization Platform from Nicira, a leader in OpenFlow network protocol concepts, is also the basis for the Quantum networking platform in OpenStack. Nicira was a heavy contributor to OpenStack before the acquisition, and it remains one now. At the OpenStack Summit on Tuesday, VMware gave these contributions a particular cast. Through close collaboration between Canonical and VMware, they will work inside the Ubuntu distribution of OpenStack, according to VMware's VP of vSphere product management Joshua Goodman.

Suse Linux and Red Hat also have distributions of OpenStack. Red Hat's KVM hypervisor is the one native to the OpenStack cloud open source code. Suse Linux is often cited as the version that works most closely with Windows Server and its hypervisor, Hyper-V. Both are keen competitors of VMware's ESX Server.

The move also reflects VMware's growing realization that it is likely to need to live with many OpenStack implementations in the future, despite its early hopes that its own cloud software stack, the vCloud Director suite, would be the basis of private and public clouds everywhere. The collaboration with Canonical gives it an OpenStack partner that is less an immediate competitor than either Red Hat or Suse.

How To Set Up Floodlight and Test OpenFlow Rules

April 09, 2013
Floodlight is an open source controller for SDN. Here’s how to set it up to use with OpenFlow-enabled switches for testing and development.

OpenFlow Test Deployment Options

April 08, 2013
OpenFlow can be introduced into production networks in several ways. I’ll look at two options for deploying OpenFlow that network engineers can use to test the protocol and get their feet wet with SDN.

SDN: Focus On The Possibilities, Not Just The Technology

March 07, 2013

Software-defined networking is in an enviable position: Everyone is excited about the concept and wants to believe in it. Among networking professionals, expectations are high. But don't make the mistake of looking at SDN as just a new tool to solve yesterday's problems.

are falling into this trap as they seek to market and monetize SDN before the new-car smell wears off. OpenFlow, because it's a standard, is an exception, but we see SDN-like capabilities baked into a number of proprietary and only partially standards-based systems. Sure, most vendors promise to support OpenFlow in addition to proprietary code, but the temptation is strong to "embrace and extend."

As chief architect of the InteropNet and CEO of a technical design company, I understand that it's normal for IT organizations to come at software-defined networking from the perspective of an engineer: What's broken that can be fixed by the ability to program a network to dynamically change its operating mode or parameters via a programmatic method?

Use SDN to make the current network better, sure. But it's more important to think differently about how SDN will help us design and build the network of the future.

F5 Acquires SDN Startup LineRate Systems
