1、A discussion about the role of benchmarking in impending legislation and how OCP is treated differently to OEM hardwareLeveling the Playing Field:Industry Standard Benchmarks and OCPDr Kat Burdett,Research and Development Engineer,TechbuyerLeveling the Playing Field:Industry Standard Benchmarks and

2、OCPDC SUSTAINABILITYSUSTAINABILITYThe growing Data Centre industry has caught the attention of various legislative bodies around the worldSome countries or municipalities have even opted for moratoriums on new data centresThe building of new and growth of existing data centres in those regions will

3、require participation in energy efficiency directivesVarious directives(e.g.,EnergyStar in the US and Energy Efficiency Directive&EcoDesign Directive in the EU)mandate reporting servers energy efficiency based on SPEC SERT 2.0 benchmark.SERT is also part of the accepted benchmarks for the ITEEsv KPI
