Minimum io size vs Optimal io size

Something is going wrong - How can the optimal_io_size
be smaller than the minimum_io_size
:
root@host:~# cat /sys/block/sdb/alignment_offset
0
root@host:~# cat /sys/block/sdb/queue/optimal_io_size
655360
root@host:~# cat /sys/block/sdb/queue/minimum_io_size
2097152
