Author Affiliations +
With the growing scale of storage system, the traditional storage strategies can not match the requirements of storage system. The attribute controlled object storage has brought about new revolution. Moreover, storage system must handle an increasing variety of data storage needs. QoSS (Quality of Storage Service) has therefore become an important issue. Based on a review of the current development in the object storage and QoS, a QoSS management framework and some optimization strategies are proposed. We implement QoSS efficiently involved with the optimizations in object-based storage systems in accordance with the proposed framework. An attribute-managed storage system with guaranteed QoSS based on extension of OSD and iSCSI protocols is developed. We mainly extend the T10 OSD standard on the delay and bandwidth attributes. The test results show that the proposed strategy can achieve the optimization of the storage systems.
