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.

How to Build a SOHO Firewall on Unix-clone Systems Like Linux
With telecommuters and small-office workers relying more on the Internet, security is becoming an increasingly important issue for systems administrators. To combat the wily hacker, many companies are turning to lightweight Linux-based firewalls. But doing so is no small feat, especially for the Unix-weary. To assuage any fears, this article will show you how to set up a Linux-based personal firewall for the SOHO (small office, home office), broadband-attached network. It also takes a look at several SOHO firewalls and determines whether or not they can keep your systems safe from intruders.
