摘要：The ability of storage and energy consumption are the core problem faced by the data centers. The shared MDS storage system takes obvious advantage of large-scale , especially PB-level scale storage systems in solving the problem of efficiency and energy consumption.So designed the optimized architecture with hot-spot buffer, and put forward a new method of performance evaluation for the system. We also analyzed the energy consumption in parallelized data requests in the system. We find out that this architecture improved the throughout in the request of chunk data, and reduced the energy consumption. The serving efficiency and performance of the system are also improved significantly.
