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

So which tool is best for your WLAN site survey? That depends on the size and scope of your planned WLAN. For medium-sized and large installations (more than 20 APs) where you plan to purchase a WLAN switched infrastructure, it's best to use the planning tool included in the WLAN switch product. These tools also make sense if you're trying to build a self-healing, robust WLAN that can adapt automatically to environmental factors and reconfigure itself for optimum performance. If you want to further augment your site survey, you can add RF modeling tools for more comprehensive planning and spectrum-analysis tools to ensure WLAN coverage.

For small installations (without a WLAN switched infrastructure) or for specialized environments like outdoor WLAN deployments, go with the laptop-based tools for your manual site survey.

And if your organization is medium to large with a specialized environment or with applications that require large WLANs or the planning and support of a repeatable enterprise-wide WLAN, a site-survey modeling tool is best. This tool is also useful if you need an accurate preinstallation estimation of how many APs you'll need and where they should sit, for example, or if you want to execute "what-if" testing without affecting the production WLAN.
