Storage optimization based on application feedback

A computer program product to optimize data storage based on application feedback, the computer program product comprising a computer-readable storage medium having computer-usable program code embodied therein, the computer-usable program configured to perform the following when executed by at least one processor:

• receive, at a storage system from an application, I/O requests associated with particular data residing on the storage system;
• process, at the storage system, the I/O requests;
• receive, at the storage system, feedback from the application indicating whether I/O performance associated with the I/O requests is acceptable;
• and
• in the event the I/O performance is not acceptable, iteratively adjust, at the storage system in response to the feedback, an algorithm for placing the particular data on storage tiers of the storage system in an attempt to bring the I/O performance into conformance with expectations/requirements associated with the application.

A system to optimize data storage based on application feedback, the system comprising:

• at least one processor;
• at least one memory device operably coupled to the at least one processor and storing instructions for execution on the at least one processor, the instructions causing the at least one processor to:
• receive, at a storage system from an application, I/O requests associated with particular data residing on the storage system;
• process, at the storage system, the I/O requests;
• receive, at the storage system, feedback from the application indicating whether I/O performance associated with the I/O requests is acceptable;
• and
• in the event the I/O performance is not acceptable, iteratively adjust, at the storage system in response to the feedback, an algorithm for placing the particular data on storage tiers of the storage system in an attempt to bring the I/O performance into conformance with expectations/requirements associated with the application.
