Clusters and Grids: Cleversafe distributes data; Virtual Iron distributes OSes

Cleversafe: Better reliability and security by letting go of data
Cleversafe is commercializing a distributed storage technology that first showed potential back in the 1990s, and that was being widely discussed in 2001 when the peer-to-peer craze hit and people first talked seriously of monetizing the grid computing model of SETI@home. The Cleversafe approach is doubly interesting because it is distributed in two senses:
The data is stored on many systems, geographically scattered around the world to facilitate disaster recovery.
Responsibility for the system is distributed. Cleversafe provides only the technology (open source) and the service. Actual storage will be purchased from a variety of companies, so that no one entity has control over users' data.
