IBM shows off XIV grid-computing tech

At Storage Expo, IBM put the XIV system on show in the UK for the first time, to highlight the company's approach to grid-based computing

IBM bought XIV a year ago so that it could obtain an innovative approach to grid computing.

The XIV disk grid-based system offers, according to IBM, "easier management, greater performance scalability, self-tuning/healing and thin provisioning". The system is designed to scale up as requirements increase and to reconfigure "on the fly".

In practical terms, you can lose a disk without affecting performance, although this demonstration was done "with crossed fingers".
