Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-15801	ESX0120	SV-16740r1_rule		Low

Description
A minimum of two physical network adapters is required in each physical server to enable networking for both the service console and the virtual machines. A minimum of two network adapters per ESX Server are required because the first network adapter discovered during the installation of the ESX Server is always dedicated to the service console by default. Up to 16 physical network adapters are supported per ESX Server. The ESX Server service console network adapter connects to the management user interface, SCP, SSH, and any other tool used to access the ESX Server’s file system. The other physical network adapter will be dedicated to the virtual machines
