IS 1GB Etherchanne sufficient for public network of RAC

Going to upgrade current 10GR2 to 11.2.0.4 and plan to set the following network:

4 connections on each system with 2 pVLAN

- pVLAN A 2-connections (one on each NIC) on switch A with LACP and jumbo Frames

- pVLAN B 2-connections (one on each NIC) on Switch B with LACP and jumbo Frames

Details:

Available NIC ports on each system:

NIC-1: port 0, 1, 2, 3

NIC-2: Port 0, 1, 2, 3

Connection requirement:

NIC-1/port 2  switch A

NIC-2/port 2  switch A

NIC-1/port 3  switch B

NIC-2/port 3  switch B

Also, Connections on switch A should be able to communicate with the connections on switch B.
