First of all, I thank God for the opportunity and trust He had given to me. Without His bless, I can't complete this article quick enough but still in good quality.
In 2/2011 issue of Data Center Magazine, I contribute an article that discusses about what filesystem really is, understanding several basic properties of filesystems and probably the most important one: how to choose the optimal filesystem for certain workload.
I welcome you to download, read and give me constructive feedback. As I am far from top notch technical writer level, feedback would allow me to enhance the quality and at the same time correct any possible errors.
PS: I owe a lot to Greg Freemyer for his inputs and critics on the early draft. He's one of the best file system expert I ever met!
