Fault-Tolerant Architecture with Stable Storage Technology

FASST - 5212

Keywords fault-tolerant architectures, stable memory technology

Start Date: 01-OCT-90 / Duration: 48 months

Objectives and Approach

FASST will investigate the components of an open fault-tolerant architecture. These components are based on the proven technology of stable storage transaction-oriented protected memory.

The main components to be developed are:

a processing unit with low-level hardware checking mechanisms and stable storage based on a standard industrial bus
an operating system kernel with fault-tolerant support and real-time properties
a stable disk with a logging file system
an implementation of a standard operating system, Unix
demonstrator applications to test the lower-level constructs and investigate fault-tolerance support at the application level.

Special emphasis will be put on the clear specification of interfaces between the various system levels. This will provide a modular set of building blocks allowing scaling of the degree of fault tolerance and enough generality to be able to build systems for different kinds of applications.
