A recently granted patent (Publication Number: US11886363B2) outlines a method and system for managing data storage performance. The method involves receiving a request from a client to write data to a storage system, estimating a requested write quality of service (QoS) parameter, determining a target write QoS parameter based on system metrics, and independently regulating read and write performance using a controller to adjust the write performance towards the target parameter. This adjustment is made within a specified time period based on feedback regarding the client's current write performance.

The system described in the patent includes a processor and computer-readable media storing instructions for receiving client requests, estimating requested write QoS parameters, determining target parameters based on system metrics, and independently regulating read and write performance using a controller. The system aims to adjust write performance towards the target parameter without increasing latency for reading data from the storage system. The regulation of write performance can involve locking out access to specific volumes associated with the storage system, and the allocated write QoS parameter for the client is determined based on factors like space utilization. Additionally, the controller utilized in the system can be a proportion-integral-derivative controller for managing performance metrics such as IOPS, bandwidth, and latency effectively.
