服务器的功能之一是存储数据,并为许多客户端提供数据服务。同时,在企业中,数据安全非常重要,并且对访问速度要求也很高,一旦出现硬盘驱动器错误或故障就可能会造成很大的破坏。因此,可靠的数据存储对于服务器是非常关键的。和PC一样,服务器的大量数据和各种软件都保存在硬盘上。如果把硬盘比喻为数据之家的话,人们希望居住于此的数据能够快速进出和安全可靠。在工业标准服务器中,普遍采用了廉价磁盘冗余阵列(Redundant Array of Inexpensive Disk,RAID)技术来实现这一理想。 One of the server’s functions is to store data and provide data services to many clients. At the same time, data security is very important in the enterprise, and the access speed is also very high, in the event of a hard drive error or failure can cause great damage. Therefore, reliable data storage is critical to the server. Like PCs, a large amount of server data and various software are stored on the hard disk. If the hard disk metaphor for the data house, then people want to live in this data can quickly access and safe and reliable. In industry standard servers, the Redundant Array of Inexpensive Disk (RAID) technology is commonly used to achieve this.
