The Study of Quality of Service in Object-based Storage Device
Zhao Shui · 2006
Object-based storage(OBS),considered as the next Internet storage protocol standard,has been accepting gradually.Object-based storage device(OSD)can give more support on applications' Quality of Service(QoS)require- ments.This paper firstly analyses object-based storage system's QoS requirements,discusses how to translate QoS re- quirements to QoS attributes and extends the OSD SCSI protocol standard to support QoS,then using quantify analysis method,analyses QoS and the process of communicating QoS information between application and OSD.finally,in- tegrating the OSD's characters,the paper proposes a QoS three-layer model called Q-Model and an optimization arith- metic called BRP in OSD.
