| 摘要: |
| 外存I/O一直是影响I/O密集型应用系统性能的决定性因素。在系统分析I/O优化调度策略及其对磁盘特征参数的需求的基础上，提出了一组面向I/O优化调度器的磁盘特征抽取方法。这些抽取方法已经被证明是高效的，并且在Traxtents-Cello调度器的实现中得到采用。 |

| Abstract: |
| IOs of the external memory are still the key factor to the performance of IO-intensive applications. Based on the systematical analysis of I/O-optimized scheduling policies and their requirement to characteristics parameters of disk, this paper introduces a set of I/O-scheduler-oriented disk characteristics extracting methods. These methods have been proved efficient and introduced into the implementing of Traxtents-Cello scheduler. |
