I’m working on a storage project with a peer that’s a system admin, I don’t change these settings often so sorry for my ignorance. He’s having issues with slowness and the storage company recommend an MTU of 9216. We have HP Comware 5700 switching between the storage and the following options are available:
Jumbo frames are on by default per port.
Layer 3 mtu size can be changed from default mtu of 1500 up to 9008 (so 9216 is not possible then?)
Layer 2 physical port max is 10,000
Currently we have storage passing on vlan 782 with mtu set to 9008 for that vlan only.
Does this setup make sense or is there some way to do it layer 2 to maximize the 10,000 size for the port?
