I have a small lab with a mix-n-match of physical hosts, a Netgear GS108T switch, and a Netgear ReadyNAS 2100 in a storage network (i.e., isolated from LAN vSwitch).
All NIC's, switch and NAS support jumbo frames. The ReadyNAS is configured with both NIC's in a LAG, as are the 2 ports on the switch.
I set all MTU's to 9000 (vNIC's, vSwitch, pSwitch, NAS).
I am getting horrendous performance and issues even seeing the LUN's on the NAS.
Is there something else I need to configure?
