Object data storage system and method to enhance IO performance in object storage system

摘要

A device and a method for processing fast object I/O in an object-based storage system are provided to realize high performance I/O by effectively prefetching object data stored in an object storage server in an object-based storage environment. A communication manager(231) receives a data access request of a client(210) and transmits the requested data to the client. An object storage manager(232) stores, deletes, and searches the requested data on the disk(240). An object cache manager(233) transmits the loaded data to the client if the requested data is loaded to a memory. An object prefetching manager(234) assigns an area to load a part of the requested data to the memory and extends the area to loads the remaining part of the requested data while the data loaded to the memory is provided to the client. An object I/O manager(234) transmits the data stored in the disk according to the memory area requested from the object prefetching manager.
