Hi,  the way Ethernet and Jumbo frames work is that ALL clients in that broadcast domain (subnet / VLAN) need to have Jumbo frames enabled.  Otherwise one host will send out 9k frames and the other expects only 1500 bytes and see’s this as an error.  Any communication between a Jumbo frame and non-Jumbo frame interface will have to go through a router  Rainer
Hello all, I am working on improving the iSCSI performance between my Celerra and ESXi Hosts.  I have a test host that I am working on to try using Jumbo Frames and teamed NICs.  I have set up everything on the host end to support Jumbo Frames (MTU=9000) and on the switch for the ports between the Celerra and the host.  I want to enable Jumbo Frames on the Celerra side, but I do not know how that will affect other clients connected to the Celerra.  Does anyone know what the impact will be on currently connected clients that are not set up for Jumbo Frames?  Thanks in advance for your help.
