This array is used to record attributes of each raid type,
make it public, and many functions will benifit with this array.
For example, num_tolerated_disk_barrier_failures(), we can
avoid complex conditions in this function, and get raid attribute
simply by accessing above array.
It can also make code logic simple, reduce duplication code, and
increase maintainability.
We can also add more raid attributes in this array, to make it
widely used.
