YouChoose: A performance interface enabling convenient and efficient QoS support for consolidated storage systems

Xuechen Zhang, Yuhai Xu, Song Jiang
2011 2011 IEEE 27th Symposium on Mass Storage Systems and Technologies (MSST)  
Currently the QoS requirements for disk-based storage systems are usually presented in the form of service-level agreement (SLA) to bound I/O measures such as latency and throughput of I/O requests.  ...  This makes resource provisioning and scheduling less informative and could greatly reduce system efficiency.  ...  ACKNOWLEDGMENTS We thank the anonymous reviewers for their constructive comments that helped us to improve the paper. This research is supported by U.S. NSF CAREER award CCF-0845711 and CRI-0708232.  ...
