  • Page 15: Introduction

    This chapter provides a general introduction to the concept and design of the Netra ft 1800 computer system. The Netra ft 1800 is a rack-mounted server that can be configured to be a hardware fault tolerant or a high-availability system.

  • Page 16: System Components

    Because comparison of the CPUsets occurs only at I/O accesses, it does not cause the system to suffer significant performance loss. In a working Netra ft 1800, comparisons can take place millions of times per second. If a discrepancy occurs, the CPUsets verify which CPUset failed, configure the failed CPUset out of the core and continue normal processing on the remaining CPUset.
