Storage system starting method and device, equipment and medium

The invention discloses a storage system starting method. The method comprises the steps of detecting a connection state and a bandwidth state of hardware equipment of a system; in response to the fact that the detection result is abnormal, reconnecting after a first preset time; modifying the default high-rate preset value in the correct connection state into a low-rate preset value through the CPU, and sending the modified rate preset value to the hardware equipment; adjusting an optimization parameter of an equalizer of the system to enable the bit error rate to be smaller than a second setvalue in response to the fact that the bit error rate reaches the high-rate preset value within a second preset time and the bit error rate of the hardware equipment is detected to be smaller than the first set value, keeping the high-rate preset value for connection, and detecting a connection state and/or a bandwidth state; and in response to the fact that the connection reaches the first preset number of times and the
