In computing, System Fault Tolerance (SFT) is a fault tolerant system built into NetWare operating systems. Three levels of fault tolerance exist:
- SFT I 'Hot Fix' maps out bad disk blocks on the file system level to help ensure data integrity (fault tolerance on the disk-block level)
- SFT II provides a disk mirroring or duplexing system based on RAID 1; mirroring refers to two disk drives holding the same data, duplexing uses two data channels/controllers to connect the disks (fault tolerance on the disk level and optionally on the data-channel level).
- SFT III is a server duplexing scheme where if a server fails, a constantly synchronized server seamlessly takes its place (fault tolerance on the system level).
