Here is my most recent blog post on ZDNet:

Another reason most IT data centers are on the way out

It is based on a conversation I had with David Scott, CEO of 3PAR, which has a technology that can dramatically increase data storage capacity. It discusses fine-grained virtualization, which means tricking IT applications into thinking they have a huge amount of data storage space allocated to their needs.

What this also means is that the efficiency of utility computing systems is significantly increased and that raises the bar even higher for internal corporate IT systems versus outside providers. Server huggers beware :-)

It's just one more reason why there will be a booming business in decommissioning corporate IT data centers over the next few years, imho.
