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.

Crash Course: Wireless Site Surveys

Site-survey planning for wireless LANs has never been simple. And with new wireless features like multiband operation (802.11b/g-2.4 GHz, 802.11a-5 GHz and so on), wireless intrusion-detection and -prevention systems, voice over WLAN and location services, it's gotten even tougher.


The site-survey process, which helps determine the placement and configuration of wireless APs (access points) in your WLAN, has been used primarily for gauging adequate coverage and avoiding channel overlap. But today's WLANs must meet specific requirements, such as providing high-performance bandwidth for each user, reliability and fault tolerance, voice support using ubiquitous high-signal-strength coverage, and overlapping coverage of three or more APs.

Site surveys also help measure performance, troubleshoot problems and mitigate interference, so you'll be conducting them regularly to support changes made to your wireless environment. Conventional manual site surveys, done by installers armed with pen and paper, are too time-consuming and grueling for many enterprises, but there are three types of software-based WLAN site survey tools to simplify the job.
