SFT III

Part of the Network software glossary:

SFT III is a feature providing fault-tolerance in Intel-based PC network server running Novell's NetWare operating system. SFT III allows two servers to mirror each other so that one server is always available in case the other one fails. (Novell doesn't say whether SFT is an abbreviation for something. However, "servers with fault-tolerance" seems to fit.) With SFT III, two servers, which can be in different geographical locations up to 40 kilometers apart, are connected by a high-speed data link through network interface cards ( NIC ). The relationship is one of peers. Either server can be taken offline for maintenance and upgrading while the other continues to run. Up to 1,000 users can be served.

Another fault-tolerant feature is that a redundant backup data link can be added. Novell calls the data link a Mirrored Server Link (MSL). A group of administrator can be notified if any system element fails. The NetWare Management System (NMS) provides a graphical map showing the SFT III servers and sends alert messages to a system console in the event of a failure.
