Nearly 18 years ago now I moved from the UK to live in the USA in Houston, Texas. One of the first things you learn when moving to Texas is that “RAID® Kills Bugs”! I find it ironic that in the next few years we might be saying “Bugs Killed RAID”. In fairness it will not just be bugs, larger disks are playing a part too, but it is clear that there is a change sweeping through the industry.
Let me explain.
For the last 25 years RAID (Redundant Array of Inexpensive Disks) has been the predominant model for protecting data across a collection of disk drives. Back in 1989 I was product manager for the Compaq SystemPro at Compaq in the UK when we introduced what was debatably the first purpose built industry standard server. It also had one of the first RAID Controllers. It was innovative and it spawned a new class of server.
