Virtualisation – Solving the Storage Problem

One of the interesting take-aways from VMworld EMEA this year was the number of companies looking to solve the “storage problem” in virtualisation.  I’m sure many of our traditional storage vendors will say that no problem exists, however there is a perception that storage, in particular Fibre Channel, is a costly solution and requires expensive administrators to keep tidy and ...

Amazon Web Services – VM Import

Amazon have announced the availability of a feature that allows vSphere virtual machines (as VMDKs) to be imported into AWS.  Today the feature is restricted to systems running Windows 2008 Server Sp2 but will be expanded in the future.  Now this concept sounds great but there’s a major drawback here – upload time.  A lot of my VMs are multi-gigabyte ...
