We are having major performance issues with our Equallogic. Equallogic is telling us that we need to buy a 3750 switch and connect the Equallogic to that instead of the 6509 switch. It is currently in a WS-X6148-GE-45AF and WS-X6148-GE-TX blade. It has 3 connections to the network of which it handles the load balancing. They tell us that due to Jumbo frames not being supported and some type of flow-control, that is the cause of all our problems. Does anyone have this configuration?
