摘要： A database system includes a master server, a pair of slave servers and a main storage carrier. Each slave server is provided with a database management system (DBMS). The main storage carrier and the pair of slave servers uses the ISCSI protocol to make the pair of slave servers serving as the DBMS and the main storage carrier serving as a database (DB) connect and communicate to further make the DBMS and the DB independent and separate. The master server performs service assignment to the pair of slave servers according to a predetermined weight value. All connections of the database are directed to the slave server with a high weight value, and the other slave server with a low weight value serves as a standby.

摘要： The method includes the steps of: a) creating a high availability (HA) network equipment cluster and network connection and assigning a virtual destination IP address (VIP address); b) defining an operating device and a backup device in the HA network equipment cluster, wherein the operating device and the backup device have respective physical addresses (MAC addresses); c) disposing a packet detection controller in the backup device; d) informing the operating device when the packet detection controller detects a packet with the VIP address as a destination; and e) the operating device announcing an ARP (Address Resolution Protocol) broadcast packet with correspondence of the VIP address and its own MAC address to drive an external network device with wrong ARP correspondence to make ARP update.
