Power supplies

Server power is derived from the power supplies that are installed in the chassis. There are no server

options regarding power supplies. Support for the x222 might be affected by the choice of the power

supply that is installed in the chassis, as described in the Chassis support section.

Integrated virtualization

Each server in the x222 supports the ESXi hypervisor on a USB memory key through two internal USB

ports (see Figure 3). The supported USB memory keys are listed in the following table.

There are two types of USB keys: preload keys or blank keys. Blank keys allow you to download a Lenovo

customized version of ESXi and load it onto the key. Each server supports one or two keys that are

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 preload keys prevents ESXi from booting, as described at the website

http://kb.vmware.com/kb/1035107. Having two keys that are 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 becomes corrupted.
