 技術摘要： |
A fault tolerant method for multiple servers includes the following steps: sensing, by each server, a voltage of hardware of the server; receiving, by a cabinet manager, data of an operating state of a blade server and data of a voltage of hardware of each server; reading, by a monitoring server, the data of the operating state of the blade server and the data of the voltage of the hardware of a monitored server, where the data is transmitted by the monitored server in a cabinet manager; determining, by the monitoring server, whether the operating state of the blade server of the monitored server is faulty or whether the voltage of the hardware has no power supply; if the operating state of the blade server of the monitored server is faulty or the voltage of the hardware has no power supply, starting, by the monitoring server, a backup virtual machine; and restarting, by the cabinet manager, a faulty server.

| Claim 1： |
1. A fault tolerant system for multiple servers, wherein the system comprises a first server, a second server, and a cabinet manager, and the first server and the second server monitor each other, wherein
the first server comprises:
a first voltage sensor, used to sense a voltage of hardware of the first server;
a first virtual machine manager, used to manage an operation of a virtual machine in the first server; and
a first monitor, used to read data of an operating state of a blade server of the second server and data of a voltage of hardware of the second server, wherein the data is transmitted by the second server monitored by the first server; determine whether the operating state of the blade server of the monitored second server is faulty or whether the voltage of the hardware has no power supply, and send a backup command to the first virtual machine manager so that the first virtual machine manager starts a backup virtual machine;
the second server comprises:
a second voltage sensor, used to sense a voltage of hardware of the second server;
a second virtual machine manager, used to manage an operation of a virtual machine in the second server; and
a second monitor, used to read data of an operating state of a blade server of the first server and data of a voltage of hardware of the first server, wherein the data is transmitted by the first server monitored by the second server; determine whether the operating state of the blade server of the monitored first server is faulty or whether the voltage of the hardware has no power supply, and send a backup command to the second virtual machine manager so that the second virtual machine manager starts the backup virtual machine; and
the cabinet manager is used to receive the data of the operating states of the blade servers of the first server and the second server and the data of voltages of the hardware of the two servers, transmit the data to the first server or the second server, and restart the faulty first server or the faulty second server.
