Intel QPI Link Power Management
Use this option to enable or disable power management for QPI (Quick Path Interconnect) links. When
enabled, QPI links are put into a low power state when the links are not being used. This lowers power usage
with minimal performance effect.
NOTE:
This option is available on servers with multiple Intel processors. You can configure it on systems with two or
more CPUs.
