PowerScale OneFS Simulator Installation Guide

Follow these guidelines to set up your virtual network:

• Reserve an IP address range for configuring your virtual cluster. You must be able to route the IP range through the hardware host for your virtual cluster. You can perform this step by setting up a virtual interface on your system with an IP address from the same subnet as your virtual cluster. Alternatively, you can configure IP addresses from the same subnet as your hardware host for your virtual cluster.
• Virtual clusters have two network interfaces: NAT and bridged. The NAT interface facilitates internal communication within the virtual cluster and does not need to be public and routable. The bridged interface facilitates client access and must be public and routable. If you are setting up VMware Workstation, VMware Player, or VMware Fusion as a host, ensure that the external network is configured as a bridged interface to enable clients to access the virtual nodes.
• It is recommended that you allocate sufficient internal IP addresses to accommodate any changes that you might want to make to your virtual cluster. If your virtual cluster does not have an available internal IP address, you cannot add new virtual nodes to your virtual cluster.
