Method for allocating channel, storage system, device, and medium

An electronic device for allocating a channel, comprising:

• a memory, configured to store a computer program;
• and
• a processor, configured to execute the computer program to:
• determine a target data segment to be transmitted in a current time period, and allocate a transmission channel to the target data segment, the transmission channel comprising a plurality of input channels and a plurality of output channels, the plurality of input channels comprising a plurality of first input channels and a plurality of second input channels, the first input channels are the input channels for inputting from a switch to the switching device, the second input channels are the input channels for inputting from a processor to the switching device;
• and the plurality of output channels comprising a plurality of first output channels and a plurality of second output channels, the first output channels are the output channels for outputting from the switching device to a storage device, the second output channels are the output channels for outputting from the switching device to the processor;
• and
• acquire a quantity of input channels and a quantity of output channels in the current time period, and adjust the input channels and the output channels based on the quantity of input channels and the quantity of output channels, to make the quantity of input channels equal to the quantity of output channels.
