Because I want to add my new storage manager.
It is not just for (single) magnetic disk.

I guess clean separation and APIs are necessary for now.
If one need to modify/extend a storage manager for better performance,
clean design and APIs are essentials.
For my purpose, I'm thinking about a pluggable storage manager
mechanism using dynamic loading, because I want to develop
my smgr independently from main codebase...
