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.

Nicira's Network Virtualization Platform Release Raises Questions

Nicira, which has just emerged from stealth mode, says it has cracked the code to deliver true network virtualization. The company claims its Network Virtualization Platform brings the capabilities and benefits of server and storage virtualization to the network, addressing what has been a physical barrier in the path to further virtualization progress. The news has been heralded as a "game changer" and "the biggest change to networking in 25 years," and a number of major companies such as AT&T, eBay, Rackspace and Fidelity are paying customers.

But following the initial hoopla, some questions are being asked about how well the Nicira platform can deliver network services via software through all of the layers of a typical enterprise network. And others ask whether decades of legacy physical network innovation can so easily be replaced.

"Think of the number of man-years that have been sunk into the networking layers that they are trying to recreate in software," says Jon Oltsik, a principal analyst at the research firm Enterprise Strategy Group. "Conceptually they are spot-on, but I think to go in and replace IP backbone networking with virtual software is a tall order."

Another analyst, Zeus Kerravala of ZK Research, also called the Nicira news significant "in theory."

To be sure, analysts like Oltsik understand the problem, which he has defined as "data center network discontinuity." The use of server virtualization has consolidated the size of data centers and improved operational efficiency, but the network has not kept up. At the same time, more demands have been placed on the network to deliver services such as intrusion detection and prevention, firewalls and load balancing. So Nicira's Network Virtualization Platform (NVP) is certainly compelling, he says.

According to a recent InformationWeek Research trending survey, if enterprises don't plan to virtualize the majority of their servers by the end of 2012, they'll be firmly in the minority. The largest growth came in the number of respondents who say they'll virtualize servers. Just 13% planned to do that back in 2010. This year, the number almost doubled, with 25% citing that goal. Server consolidation was the top driver, by far, for virtualization efforts in 2010. Now that's tied with desires for high availability, better disaster recovery, and improved flexibility and agility.

Meanwhile, other players in the network virtualization space are asking how well NVP can virtualize the full stack of layers in a network. Dante Malagrino, co-founder and CEO of Embrane, says his company is shipping virtual networking software that delivers Web application firewall protection, load balancing and WAN optimization, which he describes as network services targeted at the application layer. Nicira's NVP serves network Layers 2 and 3 ,while Embrane serves the Layer 4 to 7 space. A solution designed for one part of a network is not interchangeable with the other, he argues.
