ZHANG Bao-jun1,PING Ling-di1,PAN Xue-zeng1,WANG Jie-bing2(1.College of Computer Science and Technology,Zhejiang University,Hangzhou 310027,China;2.Hifn(Hangzhou) Information Technology Limited Company,Hangzhou 310012,China)  
A practical scheme was proposed aiming at the problem of data compression and storage under high speed network.The scheme compressed the data with hardware and software,and without any performance affection to the network speed.HIFN data reduction(DR) series high performance lossless data compression card was used in hardware.The card had multi 9630 compression chips and used the eLZS compression algorithm to provide fast data compression and decompression with satisfactory compression ratio.An eLZS module embedded in the DR device driver compressed and decompressed the data seamlessly when the hardware was failure in order to make the system run normally.The Windows driver of DR was developed in order to make DR compression card work on Windows effectively.The scheme was realized on both Linux and Windows platform and showed good performance under the test.
