With online video editing systems, file servers supporting standard file sharing protocol and achieving high I/O performance with real-timeness are required to reduce the overall system cost. AVFS is a file system optimized for the efficient storing and access of video files. Samba is a widely used file server application and enables client terminals to access files via a network. Since Samba is not adapted to efficiently process accesses to video files using features provided by AVFS, modifications of Samba such as the addition of deadline information to I/O requests are required to benefit from AVFS. In this paper, we propose rt-Samba, the Samba-AVFS cooperation method composed of a Samba VFS module and an I/O surrogate daemon using real-time features provided by AVFS. Using this method, I/O access performance is improved while keeping the amount of modifications in Samba low. Furthermore, the standard CIFS protocol is preserved, allowing the use of unmodified editing stations for accessing files. Evaluation results of a Linux file server implementation of our proposed method show that rt-Samba achieves 3 times higher read throughput and 1.1 times higher write throughput keeping the storage I/O stability compared to an original Samba server accessing files on Ext4. |
