provide Network Link redundancy
I would like to know how to provide Network Link redundancy for critical servers.
to make it simple , let's say I have VMware Vsphere 5.5, I have a server which is not in cluster group (just regular server). I would like to put 2 Network Adapters on the server, each NIC connected to a separate Cisco Switch, I need one of the NICs to be active only when the other NIC is down or the port of the Switch to which is connected is down or the Switch itself is down.
The Ip address of one NIC is 10.10.10.50 and the other NIC is 10.10.10.60, one of them should be active only when the other is down. Though I am not sure if we can have them both have the same IP address, but keep one active while other is passive.
How can I achieve that from VMware perspective as well as from Cisco Switch perspective ?
Thank you

OK....that makes sense it needs to be done on ESX server.
I checked this Video, and the Mentor is adding a new virtual switch with 2 NICs teamed up.
I wonder if he could just have added another NIC to the existing Virtual switch and would this work ?

If one physical switch itself fails, the other physical switch should stay in service.
On the Server side: each NIC is connected to separate Switch , so that to accommodate the Switch failure, if one switch fails the server will still have one NIC connected to the other Switch.
I am not sure if the server can have both NICs active with different or same IP addresses
