  "heading": "Servers shall be tested either in their individual product model configuration or, for servers which are part of a server product family, in the low-end performance configuration and the high-end performance configuration as declared for Annex II, point 3.1.(p), which includes both hardware configuration and system settings, unless otherwise specified.",
  "text": "All configurations offered within a server product family shall contain the same number of populated processor sockets used during testing. A server product family can be defined for a server with only partially populated sockets (e.g. one processor populated in a two socket server) as long as the configuration(s) are tested as a separate server product family, as required, and meet the same requirements for the number of populated sockets within that separate server product family.\nFor servers with expansion APA, the unit under test shall be tested with the expansion APA removed, when measuring the idle state power, the active state efficiency) and the server performance in active state. Where an expansion APA relies on a separate Peripheral Component Interconnect Express switch for communication between the APA and CPU, the separate Peripheral Component Interconnect Express card(s) or riser(s) shall be removed for Active State and Idle State testing of all configurations.\nFor multi-node servers, the unit under test shall be tested for per node power consumption in the fully-populated chassis configuration. All multi-node servers in the multi-node chassis shall share the same configuration (homogeneous).\nFor blade servers, the unit under test shall be tested for blade server power consumption in the half-populated chassis configuration, and the chassis shall be populated as follows:\n(1) Individual blade server configuration\n(a) All individual blade servers installed in the chassis shall be identical, sharing the same configuration\n(2) Half chassis population\n(a) The number of blade servers required to populate half the number of single-wide blade server slots available in the blade chassis shall be calculated.\n(b) For blade chassis having multiple power domains, the number of power domains that is closest to filling half of the chassis shall be chosen. If there are two choices that are equally close to filling half of the chassis, the test shall be performed with the domain or combination of domains which use a higher number of blade servers.\n(c) All user manual or manufacturer recommendations for partially populating the chassis, which may include disconnecting some of the power supply units and cooling fans for the unpopulated power domains, shall be followed.\n(d) If user manual recommendations are not available or are incomplete, then the following guidance shall be used:\n(i) Completely populate the power domains;\n(ii) If possible, disconnect the power supply units and cooling fans for unpopulated power domains;\n(iii) Fill all empty bays with blanking panels or an equivalent airflow restriction for the duration of testing.",
