Providing Quality of Service Support in Object-Based File System

Bourbon is a quality of service framework designed to work with the Ceph object-based storage system. Ceph is a highly scalable distributed file system that can scale up to tens of thousands of object-based storage devices (OSDs). The Bourbon framework enables Ceph to become QoS-aware by providing the capability to isolate performance between different classes of workloads. The Bourbon framework is enabled by Q-EBOFS, a QoS-aware enhancement of the EBOFS object-based file system. QEBOFS allows individual OSDs to become QoS-aware, and by leveraging on the random element of the CRUSH data distribution algorithm employed by Ceph, it is possible for a collection of independent QoS-aware OSDs to provide class-based performance isolation at the global level. This preserves the highly scalable nature of Ceph
