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.
