I have enabled Jumbo Frames (9000) in ESXi for all my vmNICs, vmKernels, vSwitches, iSCSI Bindings etc - basically anywhere in ESXi where it has an MTU settings I have put 9000 in it. The ports on the switches (Dell PowerConnects) are all set for Jumbo Frames. I have a Dell MD3200i with 2 controllers, each with 4 ports for iSCSI. Each of these ports is set to Jumbo Frames (9000) as well.
So now the questions:
- Do I need to log into each Windows Server VM I am running and delve into the NIC properties and manually set it to Jumbo Frames in the NIC properties in the device Manager as well?
- Whats the best way of testing that Jumbo Frames are indeed working as intended?
