You can install ESXi to a USB or SD flash storage device directly attached to the server. This option is intended to allow you to gain experience with deploying a virtualized server without relying on traditional hard disks. However, VMware supports this option only under these conditions:
- The server on which you want to install ESXi is listed on the VMware Compatibility Guide.
- You have purchased a server with ESXi Embedded on the server from a certified vendor.
- You have used a USB or SD flash device that is approved by the server vendor for the particular server model on which you want to install ESXi on a USB or SD flash storage device.
If you intend to install ESXi on a USB or SD flash storage device while ensuring VMware support for it and you have not purchased a server with Embedded ESXi, consult your server vendor for the appropriate choice of a USB or SD flash storage device.
