I/O Scheduling in Huge Object-based Storage System

Huge object-based storage system (HOSS), using objects which possess their own attributes and methods as storage interface, absorbs the advantages of both blocks and files interface. HOSS adopts the interaction among clients, metadata servers and object-based storage device, which has decreased the overload of servers in large measure. After the interactions' flows concerned with I/O operations among the three components described in detail the design and implementation of parallel I/O scheduling is described and discussed. With the buffer, the results show that it enhances the whole system performance efficiently. The performance is better when it's compared with the Lustre system
