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

Autonomous APs are useful in small-scale deployments but lack the centralized configuration management needed for a large-scale enterprise WLAN deployment. And they aren't available with built-in site survey tools. If you run a WLAN switched infrastructure, site-survey tools are typically built into the WLAN switches, so before you even purchase an AP you can use those estimation tools to gauge the number of APs you'll need and where to place them.

Aruba Networks, Cisco and other vendors offer integrated site-survey estimation tools in their WLAN switches. These tools vary slightly in their functionality but, generally speaking, work like this: After you scan in your floor plan as an image file (JPEG, GIF or PNG, for instance), the tool prompts you for your per-user bandwidth requirements; whether the WLAN will be 802.11a or 802.11b/g or both; the number of users per access point; whether voice over WLAN is required; and the areas of the floor plan that won't be wireless.

The tools then perform calculations to come up with recommendations, such as optimal placement of APs, RF channel and expected coverage. You can manipulate the results to further customize your WLAN design.

Aruba's offering is not a standalone product, but rather a "license-free" feature of the management interface for Aruba's Mobility Controller Web-based wireless LAN switch. Cisco offers a application called Wireless Control System that runs on a Windows-based server platform and must be purchased separately (WCS is a popular, $4,000 infrastructure add-on for WLAN management).
