Hi folks,
i've got a question about connection one esxi hosts to two different storages with two different mtu size configuration.
My configuration looks like this:
iSCSI_1_HP (MTU: 9000) -> -> vmnic1 (HP Storage - MTU : 9000)
iSCSI_2_HP (MTU: 9000) -> -> vmnic2 (HP Storage - MTU : 9000)
-> vSwitch5 (MTU: 9000) ->
iSCSI_3_IBM (MTU: 1500) -> -> vmnic3 (IBM Storage - MTU : 1500)
iSCSI_4_IBM (MTU: 1500) -> -> vmnic4 (IBM Storage - MTU : 1500)
As you can see i've got two adapter for connection to a HP Storage supporting MTU Size 9000 and one IBM storage that does not support Jumbo packets (MTU Size 1500).
Now my question is, how the vswitch handles both connections as the switch is also configured with a MTU Size of 9000. Perhaps it should be configured with 1500? I am not sure so i wanted to start this discussion.
