A host profile is a collection of all of the configuration settings for an ESXi host, such as storage and networking configurations and security settings. You can create a host profile from a reference host or import an existing host profile. After attaching a host profile to a host, the host can be checked for compliance with the host profile. If the host is compliant, you know the settings of the host are the same as the settings of the host profile. If the host is not compliant, the host profile can be applied to the host to make the host compliant.
