Understanding floating IP resources Dependencies of floating IP resources Floating IP By default, this function does not depend on any group resource type. Section II Resource details Understanding floating IP resources Client applications can use floating IP addresses to access cluster servers. By using floating IP addresses, clients do not need to be aware of switching access destination server when a failover occurs or moving a group migration. Floating IP addresses can be used on the same LAN and over the remote LAN. Server 1 failed Floating IP server1 server2 Access to floating IP address Client Address assignment An IP address to assign for floating IP address needs to meet the condition described below: ● Available host address which is in the same network address as the LAN that the cluster server belongs Allocate as many IP addresses that meet the above condition as required (generally as many as failover groups). These IP addresses are the same as general host addresses, therefore, you can assign global IP addresses such as Internet. You can also allocate IPv6addresses to floating IP addresses. Failover server1 server2 Client Floating IP Access to floating IP address 435
