Have a question about 10GB nic and 1GB nic in switch.
We have vswitch with "route based ip hash" with five vmnic.
Each port are 1GB.
Does this sending 5 *1GB packet or 1* 5 GB packet?
My understanding is that one time 5GB since it is ip hash.

Understanding IP Hash load balancing (2006129) [VMware KB]

There is no change in packet size (you might still want to enable Jumbo Frames). The vswitch determines which vmnic to use based on a hashing algorithm that uses both source and destination IP address. For any given communication instance, which uses the same source and destination, there will only be one NIC carrying the traffic. Load balancing comes about when there are multiple streams of traffic using diverse destinations.

You may also want to check, your configuration of physical switch for the inbound traffic configuration.

ESXi configuration is only responsible for the traffic outbound.

if i understood correctly  my case it transfer 4*1GB packet not 1*4GB, that is , packet is being transferred via one nic at time. if i use 10GB nic then chances are 10GB packet?

Andrew,
i believe that iso switch is configured lacp with multiple port.
