low-profile slots and Flex System I/O expansion slots can still be used.
Power supplies
Server power is derived from the power supplies installed in the chassis. There are no server options
regarding power supplies.
Integrated virtualization
The x220 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 one of the two internal USB ports on the x220 system board (see Figure 3). If
you install USB keys in both USB ports, 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.
The supported USB memory keys are listed in the following table.
