Fast data storing method for parallel backup data stream

In the large-scale data service applications,particularly backup and file-sharing systems,the server often face a large number of uplink data stream.In a multi-user environment,the processing of data requires frequent write operations.Due to the randomness of data store locations,disk performance reduced greatly.The purpose of the traditional buffering technology is optimizing storage ac-cording to data locality.But it’s not efficient for parallel backup data stream.So a data buffering method is presented,which rearrange the data stream and dynamically adjust the IO order to implement asynchronous data processing interface,and improve the storage per-formance of the file server.
