Techniques for dynamically adjusting the manner in which I/O requests are transmitted between a computing device and a storage device

At least one non-transitory computer readable storage medium configured to store instructions that, when executed by at least one processor included in a computing device, cause the computing device to dynamically adjust a manner in which I/O requests are transmitted between the computing device and a storage device, by carrying out steps that include:

• providing at least one I/O request to a submission queue configured to store a plurality of I/O requests;
• when at least one condition associated with the submission queue and/or a completion queue is satisfied while the plurality of I/O requests are being handled by the storage device:
• (i) updating a first operating mode of the storage device to prevent the storage device from sending interrupts to the at least one processor when I/O requests are completed by the storage device,
• (ii) processing completed I/O requests inserted into the completion queue in conjunction with respective interrupts issued by the storage device, and
• (iii) updating a second operating mode of the computing device to cause the at least one processor to periodically poll the completion queue for completed I/O requests;
• and
• when the at least one condition is no longer satisfied:
• updating the first operating mode of the storage device to cause the storage device to issue interrupts to the at least one processor when I/O requests are completed by the storage device, and
• updating the second operating mode of the computing device to cause the at least one processor to check the completion queue for completed I/O requests in response to receiving the interrupts from the storage device.

A computing device configured to dynamically adjusting a manner in which I/O requests are transmitted between the computing device and a storage device, the computing device comprising:

• at least one processor;
• and
• at least one memory storing instructions that, when executed by the at least one processor, cause the computing device to:
• provide at least one I/O request to a submission queue configured to store a plurality of I/O requests;
• when at least one condition associated with the submission queue and/or a completion queue is satisfied while the plurality of I/O requests are being handled by the storage device:
• (i) update a first operating mode of the storage device to prevent the storage device from sending interrupts to the at least one processor when I/O requests are completed by the storage device,
• (ii) process completed I/O requests inserted into the completion queue in conjunction with respective interrupts issued by the storage device, and
• (iii) update a second operating mode of the computing device to cause the at least one processor to periodically poll the completion queue for completed I/O requests;
• and
• when the at least one condition is no longer satisfied:
• update the first operating mode of the storage device to cause the storage device to issue interrupts to the at least one processor when I/O requests are completed by the storage device, and
• update the second operating mode of the computing device to cause the at least one processor to check the completion queue for completed I/O requests in response to receiving the interrupts from the storage device.
