Real-TIme I/O Pattern Recognition to Enhance Performance and Endurance of a Storage Device

摘要

Systems, methods and/or devices are used to enable real-time I/O pattern recognition to enhance performance and endurance of a storage device. In one aspect, the method includes (1) at a storage device, receiving from a host a plurality of input/output (I/O) requests, the I/O requests specifying operations to be performed in a plurality of regions in a logical address space of the host, and (2) performing one or more operations for each region of the plurality of regions in the logical address space of the host, including (a) maintaining a history of I/O request patterns in the region for a predetermined time period, and (b) using the history of I/O request patterns in the region to adjust subsequent I/O processing in the region.

1. A data processing method, comprising:
at a storage device:
receiving from a host a plurality of input/output (I/O) requests, the I/O requests specifying operations to be performed in a plurality of regions in a logical address space of the host; and performing one or more operations for each region of the plurality of regions in the logical address space of the host, including:
maintaining a history of I/O request patterns in the region for a predetermined time period; andusing the history of I/O request patterns in the region to adjust subsequent I/O processing in the region.
