In the next step, the BPB controller classifies the I/O compound modules determined
on the basis of their slice ID according to the categories "input“ or "output“.
Depending on the slice ID, the required number of bytes in the PI is determined on the
basis of a look-up table. (Inputs: blue, outputs: green)
Abb. 5 Dividing the disks into inputs and outputs
With the information determined, the memory mapping can be calculated. For the
case shown here the simplified assumption is that there only is 1 group for all inputs
and outputs in each case.
