ADAPTIVE READ PREFETCH TO REDUCE HOST LATENCY AND INCREASE BANDWIDTH FOR SEQUENTIAL READ STREAMS: abstract simplified (17715219)

• This abstract for appeared for patent application number 17715219 Titled 'ADAPTIVE READ PREFETCH TO REDUCE HOST LATENCY AND INCREASE BANDWIDTH FOR SEQUENTIAL READ STREAMS'

Simplified Explanation

This abstract discusses techniques for improving the performance of a storage system when reading data sequentially. The techniques involve prefetching data based on a predetermined distance and size, and keeping track of any failures that occur during the prefetching process. Based on these failure occurrences, the prefetch distance and size can be adjusted to optimize the system's performance. By implementing these techniques, the storage system can reduce latency and increase bandwidth when servicing sequential read streams.

Original Abstract Submitted

Techniques for providing an adaptive approach to prefetching data for sequential read streams in a storage system. The techniques can include performing prefetch operations for a sequential read stream in accordance with a prefetch distance and a prefetch size, counting or otherwise keeping track of occurrences of failure scenarios in the prefetch operations while servicing the sequential read stream, and modifying or adjusting one of the prefetch distance and the prefetch size based on the occurrences of the respective failure scenarios. In this way, host input/output (IO) latency can be reduced, and IO bandwidth can be increased, in the servicing of sequential read streams by the storage system.
