Systems and methods for allocating input/output bandwidth in storage systems

A system for allocating input/output bandwidth in storage systems, the system comprising:

• an allocation module, stored in memory, that allocates, in accordance with a pre-defined service-level agreement, an assigned amount of input/output bandwidth to an application that performs actions on a storage system;
• a receiving module, stored in memory, that receives a request from the application to perform an input/output operation on the storage system;
• an identification module, stored in memory, that identifies an amount of latency associated with fulfilling the input/output operation, wherein the amount of latency represents a severity of impact on the ability of the input/output system to fulfill other requests to perform input/output operations on the storage system;
• a calculation module, stored in memory, that calculates an amount of input/output bandwidth consumed by the input/output operation that is proportional to the latency associated with fulfilling the input/output operation instead of the size of the input/output operation;
• a deduction module, stored in memory, that deducts the amount of input/output bandwidth consumed by the input/output operation from the assigned amount of input/output bandwidth allocated to the application;
• and
• at least one physical processor configured to execute the allocation module, the receiving module, the identification module, the calculation module, and the deduction module.

A non-transitory computer-readable medium comprising one or more computer-readable instructions that, when executed by at least one processor of a computing device, cause the computing device to:

• allocate, in accordance with a pre-defined service-level agreement, an assigned amount of input/output bandwidth to an application that performs actions on a storage system;
• receive a request from the application to perform an input/output operation on the storage system;
• identify an amount of latency associated with fulfilling the input/output operation, wherein the amount of latency represents a severity of impact on the ability of the input/output system to fulfill other requests to perform input/output operations on the storage system;
• calculate an amount of input/output bandwidth consumed by the input/output operation that is proportional to the latency associated with fulfilling the input/output operation instead of the size of the input/output operation;
• deduct the amount of input/output bandwidth consumed by the input/output operation from the assigned amount of input/output bandwidth allocated to the application;
• and
• allocate bandwidth to future input/output requests from the application from the remaining amount of input/output bandwidth allocated to the application.
