Jumbo Frames in ESXi 4.x and Licensing

I'm using the free ESXi 4.0 and I ma wondering what teh different ways to enable Jumbo Frames for iSCSI are.

Also, what are the management licensing options that are open to me? RCLI and SSH are just killing me.

This KB article explains how to enable Jumbo frames. For vSwitches and vmkernel ports it's CLI only.

This blog post has some additional details.

For management of a host you can use the vSphere Client instead of the CLI. The client is very comprehensive but there are a few things (e.g. Jumbo frames) that require using the CLI.

Thanks, Moose. I am running tests today and will report back with my results.

I knew of the commands you listed. I was really hoping there was another way to do it via the GUI. I just hate having to switch between multiple tools to get things set up properly. I'm sure you know what I mean.

Just an FYI about this. I performed the testing on the SAN after it was optimized for iSCSI and turned on Jumbo Frames and I got a nearly 20% increase in performance for Random I/O.
