Gigabit network for VMWare ESXi 4 Server

A gigabit network is a must for VMWare ESXi 4. Otherwise the slow network will cause lots of problems such as the vSphere Client is extremely slow and some times it complains the server takes to long to respond and the operation can't be completed. In addition, either upload or download from the datastore browser will complain the IO error as well.

If a gigabit connection is established, all of above problems will be resolved.
