Abstract: A method includes: communicating input output (I/O) operations between a first storage controller and a storage drive, wherein the storage drive includes a first port and a second port, further wherein the first controller accesses the second port of the storage drive via a second storage controller; measuring bandwidth utilization on a first channel of a plurality of channels between the first storage controller and the storage drive; and in response to measuring the bandwidth utilization, changing a routing scheme for the I/O operations with respect to either the first port or the second port or both.
