SFT (System Fault Tolerance) Related Entries Web Links New/Updated Information Note: Many topics at this site are reduced versions of the text in "The Encyclopedia of Networking and Telecommunications." Search results will not be as extensive as a search of the book's CD-ROM. SFT is the fault-tolerant system built into NetWare operating systems. Fault tolerance is the more general term for SFT. Fault tolerance allows you to provide redundancy for hardware in a system. With SFT, you can install two disks and then mirror the contents of the main disk to the secondary disk (see "Mirroring"). If the main disk fails, the secondary disk takes over. The disk controller can also be duplicated, or duplexed, to further protect from hardware failure. Novell SFT Level III takes redundancy a step further by duplexing entire servers. If the primary server goes down, the secondary server takes over without an interruption.
