Evolution of storage #1: resilience

I contend that the next stage of evolution of storage is “Just a Bunch of Disks” (JBOD), comprised of a range of media types with different performance characteristics, and with software doing the cleverness. In this first post (1 of 2) I shall address the resilience aspects of this evolution. RAID failings Large RAID (Redundant Array of Independant Disks) systems…

Supply Chain Disintegration: A better way to buy IT

Unfortunately IT suppliers are not immune from the global economy and can fail just like any other company. I believe the best way you can protect yourself is by disintegrating the IT services supply chain. I shall explain…

BCS Data Centre Cost & Energy Simulator beta released

The simulator has come out of the Carbon Trust’s Low Carbon Collaboration initiative jointly funded by BCS and Romonet. Here are my first impressions from the preview a few weeks ago.
