recently got in 2 HP 1U servers with ESX 4.x running, w/ 2 - 2U HP Lefthand SANS boxes. Just looking for proper switch configuration to incorporate new virtual environment. New c3750 switch is fiber trunked to main 4510 switch. New vlans have been created to annex data traffic. However having issues trunking ports between the many nics and the switch. Any advice or ways to point me in the right direction would be most appreciated.
