Fault-tolerant technology is a capability of a computer system, electronic system or network to deliver uninterrupted service, despite one or more of its components failing. Fault tolerance also resolves potential service interruptions related to software or logic errors. The purpose is to prevent catastrophic failure that could result from a single point of failure.
Fault-tolerant systems are designed to compensate for multiple failures. Such systems automatically detect a failure of the computer processor unit, I/O subsystem, memory cards, motherboard, power supply or network components. The failure point is identified, and a backup component or procedure immediately takes its place with no loss of service.
Most enterprises today run a variety of mixed workloads, with different levels of business criticality. Smarter organizations are sizing and designing their IT infrastructure to match the availability requirements of their applications, and paying for just what they need. Fault-tolerant systems for those applications that must run 24x7x365. Highly available systems where up to 4 hours of downtime might be acceptable.
