Lenovo Flex System x240 Instruction Manual

Integrated virtualization

The x240 supports the ESXi hypervisor on a USB memory key via the x240 USB Enablement Kit. This kit

offers two internal USB ports. The x240 USB Enablement Kit and the supported USB memory keys are

listed in the following table.

There are two types of USB keys, preloaded keys or blank keys. Blank keys allow you to download a

Lenovo customized version of ESXi and load it onto the key. Preload keys are shipped with a specific

version of ESXi already loaded. The x240 supports one or two keys installed, but only certain

combinations:

Supported combinations:

One preload key



One blank key



One preload key and one blank key



Two blank keys



Unsupported combinations:

Two preload keys



Installing two preloaded keys will prevent ESXi from booting as described in

http://kb.vmware.com/kb/1035107. Having two keys installed provides a backup boot device. both devices

are listed in the boot menu, which allows you to boot from either device or to set one as a backup in case

the first one gets corrupted.

Note: The x240 USB Enablement Kit and USB memory keys are not supported if the SSD Expansion Kit

(90Y4391) is already installed, because these kits occupy the same location in the server.
