Re: optimal RAID configuration

I've posted a similar request 2 months ago, and basically got this. Todays RAID solutions allow a good throughput, both read and write, albeit no as with a stand alone drive with each and every one of the drives coupled to there own controller, and by dividing the different parts of oracle (rollback, logs, datafiles, redo...) you can gain optimal performance.

Check out Adaptecs site on there AAA133 raid solution. not the cheapest, but it's a good bet, I've put my money ( and my career as a DB1/2A on it...)
