Method, controller, and system for service flow control in object-based storage system

A service flow control method in an object-based storage system comprising a controller and a storage device client, the method comprising:

• receiving, by the controller, a first object IO request;
• acquiring, by the controller, a split size threshold, wherein the split size threshold is a size threshold of an object IO request to be processed by the object-based storage system;
• when a size of the first object IO request is greater than the split size threshold, splitting, by the controller, the first object IO request into multiple sub-object IO requests, wherein a size of each sub-object IO request is not greater than the split size threshold and carries a same identifier;
• sending a first sub-object IO request to the storage device client;
• starting a hibernation time period;
• receiving a response message replied by the storage device client for the first sub-object IO request, wherein the response message carries a processing result of the first sub-object IO request;
• and
• adjusting the hibernation time period according to a received processing result of an object IO request when a preset condition is met.

A device for implementing service flow control in an object-based storage system, comprising:

• a controller, wherein the controller is configured to
• receive a first object IO request;
• acquire a processing quantity threshold and a to-be-processed quantity wherein the processing quantity threshold is a threshold of a quantity of object IO requests to be processed by the object-based storage system, and the to-be-processed quantity is a quantity of to-be-processed object IO requests in the object-based storage system;
• when the to-be-processed quantity is less than the processing quantity threshold, send the first object IO request to the storage device client and update the to-be-processed quantity;
• receive a first response message from the storage device client in response to the first object IO request, wherein the first response message carries a processing result of the first object IO request;
• and
• adjust the processing quantity threshold according to a received processing result of an object IO request when a preset condition is met.
