AI Technical Summary

Technical Problem

In a storage virtualization environment, during the write access process of logical block segments, problems such as frequent migration, fluctuating access latency, and insufficient migration stability are caused by short-term fluctuations in hot spots, write-back pressure, and additional write overhead.

Method used

By collecting write access requests, snapshot chain depth, hot flip counts, and time intervals of the target logical block segment, the urgency of write access requests is determined. When the conditions for temporary acceleration are met, a temporary acceleration mapping relationship is established in the high-speed storage layer to prioritize urgent write accesses. When the conditions for formal migration are met, the temporary acceleration mapping relationship is converted into a formal mapping relationship; otherwise, the primary mapping relationship remains unchanged.

Benefits of technology

It effectively avoids frequent migrations and additional write burdens caused by short-term fluctuations in hotspots, optimizes access latency and migration stability, and improves access scheduling accuracy and operating efficiency in hybrid storage environments.

Abstract

The application relates to the technical field of data processing, and discloses a hybrid storage access scheduling method and system for storage virtualization and a medium. The method comprises the following steps: collecting a write access request, a snapshot chain depth, a hotness flip frequency and a time interval. The request urgency is determined according to the write access request, and it is judged whether the temporary acceleration processing condition is met. When the condition is met, a temporary acceleration mapping relationship is established, and the access request is guided to the temporary acceleration mapping relationship. The access frequency of a target logical block segment, the to-be-written state of a high-speed storage layer and the snapshot chain additional write amount are collected, and it is judged whether the temporary acceleration mapping relationship meets the formal migration condition. When it is judged that the formal migration condition is met, the temporary acceleration mapping relationship is converted into a formal mapping relationship. Otherwise, the temporary acceleration mapping relationship is cancelled, and the main mapping relationship remains unchanged. According to the application, the high-urgency write access response and migration smoothness are improved while the main mapping relationship is kept stable.
