For each server that you are configuring for this vSAN Ready Node environment, install ESXi and perform its initial configuration. A minimum of four servers is required to meet the requirements for the vSAN cluster capabilities.


Use the appropriate vendor-specific custom ESXi installer ISO to boot the ESXi installer ISO on the first server (esxi-01 in the example configuration) and use the defaults until you are asked to select the target device.


Select the storage device to use and select Install ESXi, overwrite VMFS datastore.

This device is often an embedded SD card, USB storage, or other vendor-specific device type.


Use the defaults for the remaining questions and, when the installer finishes, reboot the system.


Repeat the steps on the other servers.
