AI Technical Summary
Technical Problem
Insufficient disk data buffer space leads to decreased IO performance and IO stability issues, especially the frequent occurrence of conflicts between the same OBJ IO and the flushing process.
Method used
By calculating the popularity value of OBJs and monitoring the disk data buffer usage, low-population OBJs are sorted and selected for data flushing, ensuring sufficient space in the Journal area and reducing conflicts.
Benefits of technology
It improves the I/O stability and performance of the storage system and reduces the probability of insufficient Journal space and I/O conflicts.

Abstract
本发明提供了一种磁盘数据缓冲区中数据下刷的方法、装置、设备及可读介质，方法包括：根据IO请求的信息计算当前OBJ的热度值，并监控磁盘数据缓冲区的使用率；响应于监控到的磁盘数据缓冲区的使用率超过使用率阈值，根据OBJ的热度值将OBJ进行排序；根据监控得到的使用率选取设定数量的OBJ发起磁盘数据缓冲区数据的下刷操作。通过使用本发明的方案，能够减少磁盘数据缓冲区空间不足的问题，能够减少同一OBJ IO与下刷冲突事件发生的概率，能够增强整个系统的IO稳定性，提升存储系统的性能。
