Externally managed I/O starvation avoidance in a computing device

One or more non-transitory tangible computer-readable storage media storing computer-executable instructions for performing a computer process on a machine, the computer process comprising:

• maintaining a queue of one or more input/output requests intended for a storage device, wherein each input/output request comprises a position value indicative of an order in which that input/output request was received at a storage management system, wherein the storage device is configured to satisfy up to a particular quantity of concurrent input/output requests;
• calculating a difference between a first position value corresponding to a position of a first input/output request within the queue of one or more input/output requests and a second position value corresponding to a position of a second input/output request in the queue of one or more input/output requests, wherein the first input/output request was received at the storage management system before the second input/output request;
• determining that the difference between the first position value and the second position value exceeds a threshold value, the threshold value being greater than the particular quantity of concurrent input/output requests;
• preventing input/output requests from being transmitted from the queue of one or more input/output requests to the storage device in response to determining that the difference between the first position value and the second position value exceeds the threshold value;
• determining that processing of an input/output request has been completed by the storage device;
• removing the input/output request from the queue of one or more input/output requests in response to determining that processing of the input/output request has been completed by the storage device;
• calculating an updated difference between a first position value corresponding to a position of a new first input/output request within the queue of one or more input/output requests and a second position value corresponding to a position of a new second input/output request in the queue of one or more input/output requests;
• determining that the difference between the first position value and the second position value is less than or equal to the threshold value;
• and
• transmitting at least one input/output request from the queue of one or more input/output requests of the one or more input/output requests to the storage device when the updated difference between the first position value and the second position value is less than or equal to the threshold value.
