Method, device and computer readable medium of I/O management

An electronic device, comprising:

• a processing unit;
• and
• a memory storing instructions which, when executed by the processing unit, cause the electronic device to:
• in response to receiving an input/output (I/O) request for a redundant array of independent disks (RAID), place the I/O request in a corresponding waiting queue based on a stripe related to the I/O request in the RAID;
• and
• in response to the I/O request being granted to process, execute the I/O request based on storage of data of the stripe in a cache memory.

A computer program product having a non-transitory computer readable medium which stores a set of instructions for input/output (I/O) management;

• the set of instructions, when carried out by computerized circuitry, causing the computerized circuitry to perform a method of:
• in response to receiving an I/O request for a redundant array of independent disks (RAID), placing the I/O request in a corresponding waiting queue based on a stripe related to the I/O request in the RAID;
• and
• in response to the I/O request being granted to process, executing the I/O request based on storage of data of the stripe in a cache memory.
