In 2005, “green” data centers were only for the most bleeding edge IT shops that had their current energy requirements under control and could invest in forward thinking initiatives. Well for the rest of us, our number just came up…it’s 2007 and it’s time to go green!

XenSource has fired back with their own test results, which appear to show commercialized Xen performing as well, if not better, than VMware ESX. I say “appear” [...]

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 [...]

In 2007 and 2008, many analysts are forecasting tremendous growth for the data center virtualization market. The past 20 years have been pretty interesting. Legacy big iron architectures moved to client/server architectures, which then moved to open x86 architectures running Linux, and finally to “blades.” This ecosystem change has caused an explosion of whitebox and [...]
