Accepted Measurement Devices
The SPECpower_ssj2008 benchmark infrastructure provides software to
connect, control, and collect data from power and temperature
measurement devices. All measurement devices must be equipped
with at least one of the
communication interfaces supported by the benchmark. When
ordering devices for use with this benchmark, be aware that some
of these devices can be ordered in multiple configurations,
including configurations with no interface or an unsupported
communication interface.
All power analyzers must have a current NIST-traceable (or equivalent
outside of U.S.A.) calibration certificate. For more details,
please see the
calibration
section (2.13.2) of the Run and Reporting Rules.
Power analyzers are available with wide ranges of capabilities and
capacities. Computer systems have a wide range of power
requirements. Global standards for line voltage are quite
different from one country to another. Therefore, users should be
aware that any one combination of the three above contributing factors
may not provide the capability or required accuracy to measure very
high or sometimes very low power.
The list of analyzers below have been tested and found to function well
for a relatively narrow range of power provider and power consumption
conditions, essentially for volume server class computers in the one to
four socket range. The list of accepted power analyzers
below also indicates which analyzers have specific limitations
which impact compliance with the run and reporting rules for
SPECpower_ssj2008. When using one of these analyzers, one must
ensure that the listed limitations are not violated.
Results will be invalidated in cases where one of these analyzers was
used
and the system under test (SUT) exceeded the current limits of said
analyzer.
Prior to purchase of a power analyzer, SPEC recommends that the user
consult
with a qualified electrical engineer..

SPECpower Power Analyzer Acceptance Process
A process exists for a SPEC member or licensee to add software support
for a power analyzer to the SPECpower_ssj2008 benchmark and to submit
tests for review and possible inclusion by SPEC as an accepted
device. Please see
http://www.spec.org/power_ssj2008/docs/SPECpower_ssj2008-Acceptance_Process.html
for the acceptance process.
