STANDBY SYSTEM DEVICE, ACTIVE SYSTEM DEVICE, AND LOAD DISPERSION METHOD

摘要

A redundancy configuration system is configured from an active system device and a standby system device. The active system device acquires a portion of data from among stored data and outputs the portion of data, and carries out prescribed processing with respect to data that was not output. The standby system device carries out prescribed processing with respect to the portion of data when an indication of a fault in the active system device is not detected, and when the indication is detected, after having carried out the prescribed processing with respect to the portion of data, outputs a signal indicating that there is the indication. The active system device, which has received that signal, also outputs the data that was not output. The standby system device carries out the prescribed processing also with respect to the data that is input after the portion of data.

主权项

1. A standby system device that forms a redundancy configuration with an active system device, wherein,
when an indication of a fault in the active system device is not detected, the standby system device carries out prescribed processing with respect to a portion of data that is input from the active system device from among data stored in the active system device, and, when the indication of the fault in the active system device is detected, after having carried out the prescribed processing with respect to the portion of data, outputs a signal indicating that there is the indication of the fault to the active system device, and, as a result, carries out the prescribed processing also with respect to data that is input after the portion of data.
