One of the most significant ways in which servers differ from desktop computers has to do with the importance placed on fault tolerance. Fault tolerance means that a problem with software or hardware does not shut down the system, which minimizes the risk of data loss. To achieve fault tolerance, servers use technologies such as the following:
Although many of these topics are covered in detail in other chapters, this chapter is designed to show you how these server technologies help you achieve a truly fault-tolerant network. |
