Retro Networking — An Argument For Analog

Data — a collection of 1s and 0s — is pretty well understood these days, with the idea being to be able to send as many of these 1s and 0s down a given transport mechanism (copper, fiber or wireless) as possible. But, just maybe, we’re looking at this in the wrong way — maybe […]

When Old is New Again

When you think of a virtualized world, what thoughts come to your mind? I’ve been wracking my brain trying to come up with a clever idea tying-in virtual WAN optimizers with other virtual concepts. But, no great metaphor or analogy came to mind. But, then I thought about how the invention of the telephone revolutionized […]

Virtualization: Coming Soon To A Network Near You

The virtualize everything movement is well underway, but other than servers, which started getting virtual back in the 1970s with IBM (VM and MVS), and really took off in the 2000s with VMware, virtualizing storage, networks, desktops, applications and infrastructure has been more about vendor push than customer pull. While the proportion of server workloads […]

End of the Ubiquitous Six to Nine Month IT Project

I used to work in Digital Equipment Corporation’s (DEC’s) corporate IT organization at a time when DEC had roughly 125,000 employees worldwide. In hindsight, most of the time I was at DEC was spent going to meetings. For example, for one stretch of about two years, I was one of several participants in a weekly […]

Software-Defined Networking: Not If, But When!

With the demands on IT outpacing the resources available for IT, the future is all about doing more with less, and nowhere is that more apparent than in today’s networks. According to a new study from Dimension Data, the 2012 Network Barometer Report, 45% of  networks will be totally obsolete within five years, and of […]

In the Cloud, Many Enterprises Overlook the Most Critical Component

It seems that everyone today is talking about “the cloud,” but most of the discussion seems to be about putting a bunch of machines in one place to achieve elastic compute capabilities. What hasn’t received as much attention are the “networking” aspects of cloud deployments. And if there is any attention to networking, it tends […]

Virtualization Breaks Networking, Server, and Storage Silos

This year, 2011, has been an incredible year of technology innovation and change, and 2012 promises to be even more exciting as the dynamics of networking, server, and storage technology further evolve and become interconnected. During the next few weeks, I’ll outline some of my expectations of change and disruption for the coming year and […]
