To avoid network clients shut down suddenly caused by HDD damage or server crash, we have to redundancy solution for the situation. In the same time ,if more than one server in duty, the clients loading will be shared to each server equally and automatically. Once one server is crashed or out of work, reboot the clients which handled by crashed one, the clients will shift to another sever and work regularly

Advantage

• Make sure clients work normally 24 hours per day even main server is crashed
• Reduce server’s loading----light server is enough
