Appendix 1: Glossary and Abbreviations

DCM

Intel(R) Data Center Manager, a software development kit to provide basic services such as monitoring and management of power consumption for

the servers, racks, and server groups in the data center.

IPMI

Intelligent Platform Management Interface, an open standard hardware management interface specification, which defines the particular protocol for

communication with embedded management subsystem.

BMC

Baseboard Management Controller, the industrial standard IPMI protocol which provide IPMI interface externally.

DMZ

Power Saved

The difference between the power consumption of all managed server devices running under empirical power and the power consumption of all server

devices under actual running.

Virtual Electricity Meter

As opposed to the actual electricity meter, the virtual electricity meter for devices provided by Smart Grid can show real-time power consumption in the

software graphically.
