Method and device for managing input/output (i/o) of storage device

A device for use in cooperation with a storage device, the storage device at least including a first input/output (I/O) port and a second I/O port, the device comprising:

• at least one processing unit;
• at least one memory, the at least one memory being coupled to the at least one processing unit and storing instructions executed by the at least one processing unit, the instructions, when executed by the at least one processing unit, causing the device to:
• receive a first I/O request for the storage device;
• and
• dispatch the first I/O request based on a type of the first I/O request, comprising:
• in response to the first I/O request being a read request, dispatch the first I/O request to the first I/O port;
• and
• in response to the first I/O request being a write request, dispatch the first I/O request to the second I/O port.

A computer program product for managing an input/output (I/O) of a storage device, the storage device at least including a first I/O port and a second I/O port, the computer program product comprising:

• a non-transitory computer readable medium encoded with computer-executable program code for using read signatures in replication, the code configured to enable the execution of:
• receiving a first I/O request for the storage device;
• and
• dispatching the first I/O request based on a type of the first I/O request, comprising:
• in response to the first I/O request being a read request, dispatching the first I/O request to the first I/O port;
• and
• in response to the first I/O request being a write request, dispatching the first I/O request to the second I/O port.
