VMware recently released a new Emulex be2net driver version 4.1.334.0 for both ESX(i) 4.x and ESXi 5.x for the Emulex OneConnect 10Gb Ethernet Controller which is used in HP G7 Blades.
These new drivers were not supported by HP when released but HP has now certified this driver and included it its new HP ESXi images.
