I recently participated a technical trouble shooting regarding UCS jumbo frame setting to support NetApp SolidFire iSCSI storage. When the UCS MTU value in QoS setting is changed to 9216, the connection between UCS and NetApp SolidFire is lost. However, the new UCS QoS setting could be supported by the NetApp FAS iSCSI system in the same environment. A diagram as below illustrates the situation.
