| Summary: | 碩士 === 國立臺灣大學 === 資訊工程學研究所 === 97 === Network Attached Storage (NAS) servers are popular nowadays for sharing storage over the network. In recent years, NAS manufacturers took advantage of the System-on-Chip (SoC) technologies to reduce the cost of NAS servers and integrated many value-add features to attract customers. Value-add features such as peer-to-peer (P2P) applications, photo viewers, media players, and surveillance applications are offered by an entry-level NAS product on the market today. Overall, cost/performance ratios, administrative convenience, value-add features, and data security are the factors that influence the design and the user experience on NAS servers.
The Sony PlayStation 3 (PS3) is a home multimedia and game console with a powerful IBM Cell processor and a Blu-ray Disc reader, in a compact package which costs about the same as an entry-level NAS server. With a much faster processor, the PS3 outperforms the similarily priced Synology DS-207+ in many applications, but misses a NAS functionality.
In this thesis, we present the design and implementation of a NAS server with the PS3. In addition to the common features seen on NAS servers, we utilized the Synergistic Processing Elements (SPE) in the IBM Cell processor to accelerate compute-intensive applications. Our work successfully integrated NAS services and accelerated features on the PS3, and our results show that the PS3 offers higher cost/performance for surveillance and multimedia than similarly priced NAS servers. For accelerating of face detection with using 0 SPE as the baseline, we get at most 9.52 speedup.
