Dell R510 - changing NIC to use Jumbo Frames for iSCSI
Simple question really but I want to be sure. We have a Dell R510 server and I want to change the MTU on the 2nd NIC being used for iSCSI. It right now is at the default of 1514. We also have a Drobo B1200I SAN appliance and we can set a maximum MTU of 9000. The Dell server only has hard coded settings in the NIC configuration on the Broadcom BCM5716C NetXtreme II GigE of 1514, 4088, 9014 .
So I was wondering how to set this up on the 2 devices and the switch ports. Do I just set the Dell NIC to 9014, Drobo to 9000 and switch ports to 9000?? Not sure what will happen if I get a mismatch.
