I recently told my boss to put more disks in our database server, and run the database on a raid 0-1 drive and the log files on a raid 1. I told him that with a raid 0-1 the controller would be able to spread 2 concurrent reads to the different disks in the raid, so reads effectively would be twice as fast as reads on a raid 0 which already are faster than our current raid 5 He asked me which raid controllers supports this, and I think almost any newer, but i haven't done this since my first DPT raid controller, and that is 5 years ago. Which raid controller would be best for this kind of application. Should i put several controllers in the box? One for the database, one for the log files and one for the system, or just one? I have my own opinion on this, but it would make it a lot easier for me to convince him if somebody else would back me up. \Flemming To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
