I am deploying a 3 node Oracle RAC. I plan to use 2 Cisco 9372-TX switches for the Public network. Each node will have 2 10 Gb NICs and one NIC will plug into each switch for redundancy. I will use VLANS for this. My Interconnect Private network for the RAC will be 2 2960-X 1 GB switches. Each Node will have 2 Gb NICs and one NIC will plug into each 2960-X for switch redundancy. Are these just access ports? I have heard you should turn off spanning tree in this network. What will keep the nodes from looping? Does any one know of a configuration example of how the ports should be configured? I am going to enable Jumbo Frames in both the 9372-TX and 2960-X switches.
A network topology diagram would be helpful.
I dont have a lot of information of Oracle RAC but from a server's perspective if the NICs are teamed together then you can use vPC (virtual port-channel) to form a port-channel with the two Nexus 9372 switches.
Are you using the 2960X switches for management network ??
