The virtualization "waves" are 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.
Server virtualization was about saving money. Allowing multiple applications
to be consolidated onto a single server saves capital and operational
expenses. Reducing the number of servers running in the data center is a good
thing, as it also saves some carbon emissions as well. But is that it? If so,
that’s more like a ripple than a wave. Don’t get me wrong, reducing
power, cooling, server count and consolidating apps is a good thing, but it's
not the whole story. Not by a long shot.
I don’t believe that this is it. In fact, I think we are still in the
beginning stages of realizing what virtualization can do. It’s really the
enabling technology that fuels ... (more)

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 IO, the physical world is typically defined by dedicated
connections to Input/Output (I/O) devices such as disks, networks, CD-ROMs,
consoles, et... (more)

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.

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.
Dan Kusnetzky asks an interesting question on his blog, “What is
virtualization 2.0?”
