Memory resource allocation for file system prefetching
Zhe Zhang, Amit Vasant Kulkarni, Xiaosong Ma, Yuanyuan Zhou · 2009
As an important technique to hide disk I/O latency, prefetching has been widely studied, and dynamic adaptive prefetching techniques have been deployed in diverse storage environments. However, two issues are not well addressed by previous research: (1) how to handle the prefetching resource allocation between concurrent sequential access streams with different request rates, and (2) how to coordinate prefetching at multiple levels in the data access path.
