You can access the IPMI IP address of each node through a browser, check the BIOS settings, and remotely install and configure ESXi.
Prerequisite
Precaution

The following will use Dell servers (C6420) for each node as an example to illustrate the procedure of installing and deploying the ACOS cluster.
