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.

Toward More Reliable Wireless With AirMagnet Enterprise 10

February 27, 2012 04:40 PM
Posted by Lee H. Badman

If the phone isn't ringing, then your wireless users must not be feeling any pain, right? That can be a dangerous assumption in large, complicated wireless networks. Some issues may not be crystallized enough to raise your clients' ire, but the fact remains that performance is degraded. AirMagnet's latest Enterprise version wants to make hard-to-find problems more obvious even as the WLAN gets ever more complex.

Riverbed's Granite Virtualizes Branch Office Storage

February 10, 2012 09:00 AM
Posted by Howard Marks

When Riverbed and others brought WAN acceleration to the market around the turn of the century, many of us hoped that with WAN acceleration we could pull the servers, and the headaches they cause, from branch offices. Unfortunately, many organizations found reasons to keep servers in the branches. Riverbed's new Granite appliance allows organizations to keep servers in their branch offices while eliminating many of the headaches through what Riverbed's calling Edge Virtual Server Infrastructure.

Red Lambda: Security Revolution Or Just Evolution?

November 14, 2011 07:00 AM
Posted by David Hill

Security statistics are depressing. The bad guys seem to be overwhelming the good guys, even when the good guys are well-known security vendors. So when an emerging company, such as Red Lambda, claims to have software that significantly improves the odds for the good guys, you need to pay close attention.

Certificate Authority Compromises Are Global In Reach

September 09, 2011 01:48 PM
Posted by Mike Fratto

There has already been a lot written about the compromise at DigiNotar, GlobalSign and Comodo. One day we will look at the summer of 2011 as the time when the PKI collapsed. That's not hyperbole. The problems with certificate authorities and the inherent weakness they present have been known for years--a fact we alluded to as far back as 1997. Browsers accept certificates as trusted in that they have the signing CA certificate in their local browser store. Browsers do not check that a particular CA is authorized to actually issue a particular server certificate. The trust is universal. That is why the attacks on DigiNotar, GlobalSign and Comodo are so serious and have global impact.
