When preparing the cluster offsite in a safe room, the consultant should ensure that the Foundation VM is correctly configured to handle IPMI networking. Implementing a virtual switch dedicated to the IPMI network within the Foundation VM environment ensures that there is a segregated and controlled network path for IPMI traffic, which is crucial for initial hardware configuration and management. This setup facilitates the secure and efficient foundation process before the cluster is moved to the data center.References: Nutanix Foundation Tool Guide, Nutanix Network Configuration Best Practices.
