Programme Description
In the rapid development of the information age, knowledge management and information sharing enterprise characterized by internal and external work, has become key to the success of an enterprise.However, enterprises in the establishment and maintenance of information management systems will encounter data storage I / O bottlenecks.Especially in the enterprises to establish a WWW server management system, EMAIL server management system, database management systems, application server management system, office automation systems and file server management system and other office and engineering environment, how to handle the amount of total data storage 57% of frequentlowercase data storage problems, has been a global problem.Hewlett-Packard, Online Technology Development Co., Ltd. Beijing secret and Wuhan East Lake Storage Technology Co., Ltd. jointly launched the SME DCD (Disk Caching Disk) server solutions.The program draws on the hard disk space for cache, the hard disk in a continuous way of recording the maximum bandwidth to absorb frequent lower-case (Note: I / O to disk is divided into 512 bytes of each block to block, ranging from 64K bytes, which less than 64Kblock to lowercase), then the disk is idle Cach data disk drive to write data back to the purpose, which allows the user to the price of hard disk space, got a huge cache space, greatly enhance the frequent I / O access performance.And the data on the hard drive cache, RAM cache than in a much higher reliability.
