(1)LwA,m: The declared mean A-weighted sound power level (LwA) is calculated per section 5.2 of ISO 9296 (2017) with data collected using the methods that are described in ISO 7779 (2010) . Engineering data presented here may not be fully compliant with ISO 7779 declaration requirement.
(2)LpA,m: The declared mean A-weighted emission sound pressure level is at the bystander position per section 5.3 of ISO 9296
(2017) and measured using methods that are described in ISO 7779 (2010) . The system is placed in a 24U rack enclosure, 25 cm above a reflective floor . Engineering data presented here may not be fully compliant with ISO 7779 declaration requirement.
(3)Prominent tones: Criteria of Annex D of ECMA-74 and Prominence Ratio method of ECMA-418 are followed to determine if discrete tones are prominent and to report them, if so.
(4)Idle mode: The steady-state condition in which the server is energized but not operating any intended function.
(5)Operating mode: The maximum of the steady state acoustical output at 50% of CPU TDP or active storage drives for the respective sections of Annex C of ECMA-74.
(6) Customer Usage Operating mode: The operating mode is represented by the maximum of the steady state acoustical output at 25%~30% of CPU TDP, 2 .5%~10% IOPs load, and >80% GPU load as the components showed in the above configurations.
