Fault Tolerance

Paper Summary:

In this article, the writer first points out that errors in a network system can result in serious financial problems for a company. The writer then explains that this has led to an increased demand for products such as magnetic tape backup, recording systems, UPS and fault tolerance systems that help in protecting the company's network systems against data loss. The writer also notes that fault tolerant devices are also called mirroring products since they work on redundancy by providing identical copies of data and program files. The writer concludes that ,while fault tolerance systems are needed in order to avoid potential loss of data and revenues, there are some drawbacks attached to their implementation, such as cost.

From the Paper:

"While these technologies are standard, there are some specialized fault-tolerant products such as Novell's System Fault Tolerant (SFT) NetWare are not that well understood and hence not used that often. Fault tolerant devices are also called mirroring products since they work on redundancy by providing making identical copies of data and program files. The fault tolerant devices make use of the server and the hard disk to mirror files and each of these files has the exact same formatting and content as the original copy."
"Fault tolerant technologies help in providing security to a large extent. This kind of security is more protective than simple back up or data recovery system. A fault tolerant network is not the same thing as a fault resilient system."
