VIA requires the following infrastructure.
You need a laptop/desktop or an ESXi host (called management host) to run the VIA VM.
A laptop works well for imaging a single rack while a management host is recommended if you are imaging multiple racks. The laptop need to be connected to the management switch of the rack being imaged. If there are multiple racks to be imaged, this would mean physically moving the laptop for imaging each rack. The management host is connected to all the management switches through an internal switch, so the connection to the rack being imaged can be managed remotely.
Desktop or laptop (Windows or Mac) with 4 GB memory and a multi core processor to access the jump VM. A Windows laptop must have Workstation 8 or later and a Mac should have Fusion 4 or later installed on it. You also need a network adapter, a cable, and a 4-port unmanaged switch.
Management host - a standalone VMware vSphere ESXi 6.0 or later server to host the Windows jump VM. The management host must have at least two NICs, with one NIC connected to the corporate network and one NIC connected to the private network.
If you are using a management host for imaging, you need a jump VM to access VIA
Private managed switch. Private indicates that it is being used only by you. A managed switch provides the ability to configure, manage, and monitor your LAN, which gives you greater control over how data travels over the network and who has access to it.
