I am Trying to achieve Network Redundancy in network which have 1 server & lots of node which use 1 switch for each. As per various forums for achieve Redundancy in network i should use Layer 3 switch. But i think one possibility (may its wrong) Test scenario:- As server there are 2 NIC cards. From eth0 ie NIC 1's wire goes to Main Switch from Main Switch wire goes to Node1's Switch & as Daisy Chain its going on till last Node's Switch. From Last Node Switch wire comes to complete Redundancy to eth1 ie NIC 2 in server.
Can anybody tell me whether this thought really work in same network means all ip within 10.111.17.0 to 10.111.17.254 Or I have to write program which maintain ip address & check its connectivity. If one node fails to communicate with server's 1 NIC then that java program send request from different NIC which have different network address '10.111.18.xxx'. I can keep program in each node so they can change their own ip as per NIC response.(These program is also theoretical right now if i got reply yes then i try to find out how to write these program) By this way i can achieve Redundancy in my Network & can use Layer 2 switches so cost also less.
Any suggestion/idea/clue regarding this thought?
