Appendix I

Accessing Power and Performance Data

This chapter describes how to collect the power and performance data, including power

consumption, inlet air temperature, and processor utilization of NEC Express server in usual

operation. These are defined in ENERGY STAR® Program Requirements for Computer Servers

and must be available to users.

The sample program shown below is verified to be run normally on Windows Server® 2008

Enterprise 32bit (x86) Edition.

POWER CONSUMPTION

Run the following commands to access power consumption readings on BMC (Baseboard

Management Controller) via IPMI (Intelligen Platform Management Interface).

Network Function Code: 3Eh (Controller-specific OEM)

Command Code: 0Bh (Get Current Sensor Data)

Shown below is a sample file created by Visual Basic Script (e.g. Power.vbs).

' Start Script

Option Explicit

' Prepare for IPMI Driver

Dim osvc, oclass

Dim oinstance, oipmi

set osvc = getobject("winmgmts:root\wmi")

set oclass = osvc.get("microsoft_ipmi")

for each oinstance in osvc.instancesof("microsoft_ipmi")

set oipmi = oinstance

'Format the IPMI command request

Dim oinparams

set oinparams = oclass.methods_("requestresponse").inparameters

oinparams.networkfunction = &h3e ‘ OEM NetworkFunction

oinparams.lun = 0

oinparams.responderaddress = &h20

oinparams.command = &h0b ‘ Get Current Sensor Data Command

oinparams.requestdatasize = 0
