YoutubeESXi 4.0 supports Jumbo Frames
Some people out there, such as in this post, have noticed a statement in the ESXi 4.0 Configuration Guide which says (on page 54):
"Jumbo frames are not supported for VMkernel networking interfaces in ESXi"
I am happy to say that this is merely an error in the documentation. In fact, ESXi 4.0 DOES support Jumbo Frames on VMkernel networking interfaces. The correction will hopefully appear in a new release of the documentation, but in the meantime, go ahead and configure Jumbo frames for your ESXi 4.0 hosts.

Unfortunately, the "TrackBack URL" is broken... Any other reference to how to enable Jumbo Frames in ESXi 4.0 ? Any instructions would be greatly appreciated!

@Drew: To enable jumbo frames on ESXi, you can use the following vCLI command: esxcfg-vswitch -m 9000 vSwitchX.
Of course, you need to have jumbo frames enabled throughout the entire network path, including the physical switches, physical NICs, and the guest VM vNIC (e.g. using vmxnet2 or vmxnet3).
