It is not simple, because with I/O priority management enabled, your velocities 
will change because I/O delays will be taken into consideration. They will 
probably change differently for every serviceclas. RMF can report your current 
velocities and what they would have been with I/O priotity management enabled. 
You must adapt your velocities and keep a close watch on the effects in the 
first period after implementation.
