AKA HAS, High Availability Server. A set of features that allow a computer to continue and provide service with no loss of data and only a brief interruption of service, in the fase of a single failure. HAS are typically said to be SPOF (Single Point Of Failure) free. They are designed to have the ability to tolerate any single component falure. If there is interest, we can start a discussion on what such a computer looks like.
