The x240 offers USB flash drive options preloaded with versions of VMware ESXi. This is an embedded version of VMware ESXi and is fully contained on the flash drive, without requiring any disk space. The USB memory key plugs into port 1 on the optional x240 USB Enablement Kit, 49Y8119. The kit offers two USB ports however only one VMware ESXi memory key can be installed.
Note: The SSD Expansion Kit cannot be installed if the USB Enablement Kit, 49Y8119, is already installed as these kits occupy the same location in the server.
