Intel Intelligent Power Technology provides policy-based power
management that covers all five usage scenarios for significant
energy cost savings. Intel Intelligent Power Node Manager is built
into Intel Xeon processor-based servers and reports individual
system-level power for use in management consoles and higher-
level policy tools to manage server consumption. With Intel Data
Center Manager (Intel DCM)—software technology that provides
power management up to the data center level for groups of
servers—you can increase power conservation for servers, racks,
groups of servers, and data centers.
Intel IT has successfully monitored and capped power consumption
across individual servers and groups of servers with Intel Intelligent
Power Node Manager and Intel DCM. Tests showed that server
power consumption was reduced by approximately 20 percent when
running an I/O-intensive workload without affecting performance.
At that reduced level of power consumption, Intel Intelligent Power
Node Manager was able to dynamically balance power requirements
so that overall performance was maintained, demonstrating that
capping can help maintain business continuity.13
