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.

End to End Application Performance ManagementTech Center

You don't deliver applications in a vacuum. Applications and the infrastructure that supports them are dynamic systems that change over time. Unrelated system using the same network, servers, and storage can adversely impact application performance. With virtualization, the risk of one virtual server impacting another is quite real. Our End to End Application Performance Management (APM) Tech Center delivers best practices, emerging trends, new products and strategies to help you delivery applications effectively.

VMware's Casado: Network Virtualization The Right Way

The true benefits from network virtualization will come from simplifying the network and applying it to broader use cases, rather than bickering about the finer points of vendors' SDN products, according to VMware's Martin Casado.

Behind The Scenes Building The InteropNet

Network engineers are busy preparing the network infrastructure for the multi-vendor InteropNet that will support the upcoming Interop conference. Preview the action in our video.

The Truth About Network Performance: It's the Applications, Stupid

September 05, 2012 03:16 PM
Posted by Jim Rapoza

Your end users aren't sitting around, lamenting network performance. They're cursing the apps they're using. Here's why your enterprise should start focusing on application performance as well.

BufferBloat And The Collapse Of The Internet

April 21, 2011 07:00 AM
Posted by David Greenfield

It seems that every few years there's yet another prognosticator that the Internet is about to collapse. Once it was the stellar growth in bandwidth demand driven by the phenomenal increase in Internet-connected devices. At other times, it was the lack of Net neutrality (see this video). Still other times, it was sinister attacks on BGP or the fact that we've run out of IPv4 addresses.

Welcome To The WAN Optimization Shell Game

April 11, 2011 09:30 AM
Posted by David Greenfield

In the early days of Ethernet switch vendors, IT organizations would routinely hear vendors profess to deliver better line rate performance at 20 percent less than the market leader. The catch, because there was always a catch in this industry, was that performance was only achievable in specific circumstances. Turn on port monitoring or enable encryption and Ethernet switch performance would skid to a halt. A similar story may be brewing in the WAN optimization space. While vendors, such as Blue Coat, Riverbed, and Silverpeak, rush to tell us about how they can achieve incredible performance improvement, turning an OC-3 into an OC-12, other limiting factors may prevent end users from actually seeing those numbers.

The Importance Of Correcting Packet Loss In VDI

March 30, 2011 11:13 AM
Posted by David Greenfield

Recently, on the LinkedIN WAN optimization professionals group, I participated in a conversation around whether virtual desktop infrastructure (VDI) is ready for the WAN. Face it, delivering responsive VDI over the WAN is going to be a challenge. One of the interesting points that came up was the importance of correcting for packet loss when considering WAN optimizers.

What WAN Optimizers Can Learn From Firewalls

March 11, 2011 10:28 AM
Posted by David Greenfield

Listening to the give and take about WAN optimizers made me remember another battle between networking giants. It was nearly 10 years ago, during the early days of firewalls, when it seemed Marcus Ranum, then with Network FlightRecorder, would go head-to-head with Check Point's Gil Schwed on a weekly basis. Ranum was among the early creators of the application proxy and was vociferous about the value of delivering a firewall that terminated and inspected every session before passing the contents onto the destination. It was very effective, very secure and yet ultimately eclipsed by competing approaches.
