Guys I really can't see any reason for my ESXI host to not be sending out jumbo frames...
Can someone help with this?
I think I have it all setup right - screen shots of my MTU settings on my iSCSI network adapter:
And my port binding:
And those are the only settings I can see relating to this...
Something Interesting I noticed was that when I send a ping out of my ESXI host to the SAN as per that article: http://rickardnobel.se/troubleshoot-jumbo-frames-with-vmkping/
when the frame size is 1000 it takes 0.1 ms to return.
But when it is 9000 in size it takes 0.9 ms to return.
This would suggest that something is having to fragment the packets. Most likely my esxi host as the switch cannot see ANY jumbo frames coming in on that interface.
