Virtualization: After Servers, the Infrastructure Needs to be Virtualized

Fri, 13 Jun 2008 07:30:00 EDT

Is 'Virtualization 2.0' just a catchphrase? Is it a new term that analysts can cling to? Is it a re-hash of technology from 20 years ago? Is it new? Is this really new technology that will have a material impact on how data centers are managed? If not, then it's just another marketing term that will fall by the wayside in due time.

The Next Virtualization Waves Are Forming

Fri, 13 Jun 2008 07:00:00 EDT

2007 was a breakout year for virtualization, as it finally hit the mainstream. But where do we go from here? The virtualization 'wave' is just forming. And while server virtualization is at full crest, there are many more waves behind this that are taking shape and quite frankly, are more significant.

Virtualization Viewpoint: It's Easy Being Green

That wise prophet Kermit once said, 'It's not easy being green.' Actually, it is, but you wouldn't get that impression based on some of the 'green solutions' we're seeing in the market. Isn't the easiest way to reduce power and cooling to remove those things that create demand for power and cooling? Physical devices are the culprit here. The more we add, the more power and cooling we need. Simple math. Turning down fan speeds, slowing CPUs, etc...these are nice tweaks that nibble at the edges but in reality, don't address the root problem.

Cornerstones of Virtualization: I/O Virtualization Defined

Tue, 22 Apr 2008 09:45:00 EDT

Recently I talked about what I see as the next 'waves of virtualization' taking the industry, I talked about I/O Virtualization as a key (maybe THE key) cornerstone, so I thought it might make sense to describe just what it is and why it's important. Like all forms of virtualization, the physical world is masked and abstracted into a virtual representation, allowing for higher utilization or increased agility, etc. For I/O, the physical world is typically defined by dedicated connections to Input/Output (I/O) devices such as disks, networks, CD-ROMs, consoles, etc.
