METHOD AND SYSTEM FOR BALANCED STRIPING OF OBJECTS

摘要

A balanced distributed object storing method and a system thereof are provided to reduce concentration of objects and I/O(Input/Output) bottleneck by distributively storing the objects to different storage devices with an object ID when an object-based system distributively stores the objects by forming a RAID system with OSTs(Object Storage Target). Each file server(10-11) transmits a data write request. Each OST(13-14) generates the object having the same object ID according to an object generation command received to store the data. A metadata server(12) transfers the object generation command including the object ID to each OST by a data write request. Each file server distributively stores the data to the OSTs by using the object ID. Each file server calculates a reminder by subtracting a predetermined value from the object ID and dividing a subtraction result into the number of OSTs, and determines the OST moved from the first OST by the remainder as the first OST for storing the data.
