hello all,

which load balancing mechanism would you recommend to use in vmware when 2 nics are plugged to 2 different stacked switches and etherchannel and other lagg configurations are not available on the switch side ( please do not ask why )

this platform uses 6.1 or above

the vswitches are not distributed

thanks for your help

Route based on originating virtual port ID

The virtual machines are just balanced over the physical available NICS, and requires no special configuration on your physical network switches.
thanks. i've been using either that setting or source mac but needed an "external" opinion ;)

can you confirm the switch can send to either port including the one that is not currently selected by vmware ?

do you know anything regarding the repartition ? if i install exactly 2 hosts, will i necessarily end up with one host on each port ?

can you confirm once the machine is up, vmware will never change it's mind unless the link goes down ? ( afaik, vmware keeps the same port even across reboots ). do you know a way to change the affected physical port ?

thanks a lot for sharing your knowlege

What you need to remember is the teaming selection on the ESXi server configures the outbound traffic from ESXi, not inbound traffic to the ESXi host.

Route based on originating virtual port ID is basic teaming, its round robin.

so if you have two physical nics (uplinks),

VM-A starts (power on) and uses vmnic0
VM-B starts (power on) and uses vmnic1
VM-C starts (power on) and uses vmnic0

they will continue using those nic, unless a vmnic fails.
thanks a lot

best regards
just adding extra points. Sorry for the additionnal notification
