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.

Crash Course: Wireless Site Surveys

The first are those integrated into your AP infrastructure that provide initial estimations of WLAN coverage and real-time dynamic radio management. The second type run on laptops to assist in the on-site survey walk-through. The third are full-blown modeling applications that provide intensive WLAN coverage calculations.

These tools offer interfaces that let you run visualizations of your WLAN and design it for ubiquitous coverage. With visualization, you can virtually manipulate or relocate access points, sensors and antennas without having to physically move them by trial-and-error. Site-survey tools also let you test "what if" scenarios (the addition of access points, hardware failures, a swell in the number of users); identify and avoid sources of interference; and support a performance baseline for your WLAN.

You may decide not to perform a site survey if your initial WLAN deployment is small and you're building out your WLAN incrementally. But once that WLAN starts to expand, a site survey is inevitable.


If you're building a WLAN at a site with no existing wireless infrastructure, the big question is how many APs you'll need and where they should go. Depending on the AP's architecture--whether it's an autonomous AP or a thin AP with a WLAN switch--you may be able to hold off on buying them and use an AP estimation tool first.
