DCD server solution for SMEs



Programme Description
In the rapid development of information age, knowledge management and information sharing is characterized by the enterprise, the 外部 collaboration has Chengwei key to the success of a business. 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 total data storage capacity 57% of the frequent lowercase data storage problems, has been a global problem. Hewlett-Packard, Beijing Science and Technology Development Co., Ltd. and the secret line of 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 hard disk to form a continuous record of the maximum bandwidth to absorb frequent lower case (Note: I / O to disk, each block is divided into 512 bytes to 64K bytes of the block ranges in which less than 64K block to lowercase), the disk is idle then Cach data disk drive to write data back to the purpose so that the price of hard drive space users get a huge cache space, greatly enhanced the frequency I / O access performance . And data in the hard disk cache in RAM cache than with much higher reliability.
