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

Heavy Lifting

High-powered wireless site-survey tools--full-blown modeling applications, such as Motorola's Wireless Valley and AirTight Networks' Planner--let you model the entire WLAN. They will cost you a little more too, from $4,000 to $6,000. They import your floor plan and "model" the environment with details such as building materials and precise distances. You get an accuracy of 85 percent out of the box with a 2 dB to 3 dB standard deviation. These tools are best for large, complicated WLAN environments, if you're planning a repeatable WLAN design or if you want to test "what-if" scenarios.

Trapeze's Ringmaster is an integrated tool that models the RF environment and automatically adjusts APs as needed. Once you've imported your floor plan, you can customize it with specifics such as drywall, cement wall, metal studs and so on. APs can be moved or added virtually, and walls can be torn down to test and plan alternative WLAN designs.

AirTight also offers a site-survey planning service ($500 per 50,000 feet) where it models your WLAN so you don't need to purchase the vendor's modeling application (which costs $4,000). And the company includes a one-time offer of free planning services with the purchase of its AirTight wireless IDS starter kit. Motorola's Wireless Valley LAN Planner, meanwhile, is a component of Wireless Valley, a suite of RF design tools that let you model different types of RF systems.
