How to add a new dedicated network for a virtual machine to obtain full-capacity bandwidth and to monitor network traffic in Virtualization Station?

What is a “Dedicated Network”?
When many Virtual Machines (VMs) share the same physical Network Interface Controller (NIC), the transmission rate will decrease. Therefore, if a certain VM has to send or receive lots of data, then the Virtualization Station can allocate a specific NIC to be used by this VM only, called a “Dedicated Network”.

The Virtualization Station allows you to set up a dedicated network for VM (Virtual Machine) use only. The number of dedicated networks depends on how many NIC (Network Interface Controllers) you have. The maximum number of dedicated networks is 8. (Please note: the NAS needs one NIC to operate; therefore, the first NIC would be set up as the “Default Gateway” instead of being a dedicated network for VM. In addition, if you just plug one cable in NIC, the VMs’ network would be disconnected.)

NAS with two NICs

If you only have two NICs, the first NIC would be taken by NAS and the second NIC would be set up as “Dedicated 1”; therefore, you would only have one dedicated network in this case.

NAS with four NICs

Enter the Virtualization Station and click “Network Setting’.

The first NIC would be taken by NAS and the second NIC would be set up as a “Dedicated 1”

Click “Add Dedicated”

“Dedicated 2” will be added and Ethernet 2 (the second NIC) will display to notify the user that this NIC has been taken by another dedicated network. As a result, this NIC cannot be selected.

Select “Ethernet 3” and click “Apply”. (Please note: When you adjust or change the network setting from NAS, you can select an Ethernet and click “Restart” to reset the Ethernet for dedicated network use; otherwise, your VM’s (virtual machine) network could be disconnected.)

You can follow the same steps, with adding dedicated 3, to add dedicated 4.
