We all knew it had to happen at some point. You had the old guard running servers on physical platforms, sprawling through the data center, using more and more power generating more heat. Then came virtualization via the hypervisor, condensing the many physical servers into a few. This, of course, could not take care of [...]

Today Egenera & Dell announced the start of shipping their Dell / PAN system. I believe this marks a new strategic direction for the company, and hopefully, a new set of infrastructure management options for mission-critical users of any kind of physical/virtual environment.
Egenera has been best known for combining its high-performance BladeFrame hardware with its [...]

Virtualization cuts across just about all of what you might find in the data center. Clients, servers, applications, storage systems, data networks, and security can all be virtualized to one degree or another. And chief executives are discovering that virtualization has the potential to not only improve the balance sheet, but strengthen competitive advantage and [...]

What is a utopian data center? It has always been desired for obvious reasons, but has never really been attainable. Data centers have become overly complex over the last decade due to so many different levels of management to keep up with the growing demand of servers and trying to keep it from getting out [...]

In my last couple of posts, I discussed the journey that we are on and how applications will be purchased and deployed going forward. In this post, I’ll discuss how I see systems being provisioned to support these applications.
In order to support an environment where applications are purchased as a service, with performance and availability [...]

I’m going to post a series of blogs on where I think the industry is going, [...]

Posted in High Availability on Mar 5th, 2007
Many virtualization solutions running on distributed systems claim the ability to automatically move an application between processing resources in the case of a hardware or application failure. This eliminates the 1:1 mapping for high availability (for every active server there is a corresponding active/passive server) and therefore creates N+1 high availability.
That’s great but what is [...]
