Main Configuration File¶
Description of the three top-level configuration objects used by the environment loader:
data_center_configuration (object)
hvac_configuration (object)
server_characteristics (object)
Field Reference¶
data_center_configuration (object)¶
- NUM_ROWS (integer)
Number of rack rows in each hall.
- NUM_RACKS_PER_ROW (integer)
Number of racks in each row.
- RACK_SUPPLY_APPROACH_TEMP_LIST (list of floats)
Supply-air approach temperatures (°C) for each rack; list length must equal NUM_ROWS × NUM_RACKS_PER_ROW.
- RACK_RETURN_APPROACH_TEMP_LIST (list of floats)
Return-air approach temperatures (°C) for each rack; same length and order as the supply list.
- CPUS_PER_RACK (integer)
Number of CPU cores per rack.
- GPUS_PER_RACK (integer)
Number of GPU devices per rack.
hvac_configuration (object)¶
- C_AIR (float)
Specific heat capacity of air (J·kg⁻¹·K⁻¹).
- RHO_AIR (float)
Air density (kg·m⁻³).
- CRAC_SUPPLY_AIR_FLOW_RATE_pu (float)
CRAC unit supply air flow rate (per unit).
- CRAC_REFRENCE_AIR_FLOW_RATE_pu (float)
Reference supply air flow rate for CRAC (per unit).
- CRAC_FAN_REF_P (float)
Reference fan power for CRAC (W).
- CHILLER_COP_BASE (float)
Base coefficient of performance for the chiller.
- CHILLER_COP_K (float)
Temperature coefficient for chiller COP.
- CHILLER_COP_T_NOMINAL (float)
Nominal temperature (°C) for COP calculation.
- CT_FAN_REF_P (float)
Reference fan power for cooling tower (W).
- CT_REFRENCE_AIR_FLOW_RATE (float)
Reference air flow rate for cooling tower (m³·s⁻¹).
- CW_PRESSURE_DROP (float)
Pressure drop in condenser water loop (Pa).
- CW_WATER_FLOW_RATE (float)
Water flow rate in condenser water loop (m³·s⁻¹).
- CW_PUMP_EFFICIENCY (float)
Pump efficiency of condenser water loop.
- CT_PRESSURE_DROP (float)
Pressure drop in cooling tower water loop (Pa).
- CT_WATER_FLOW_RATE (float)
Water flow rate in cooling tower loop (m³·s⁻¹).
- CT_PUMP_EFFICIENCY (float)
Pump efficiency of cooling tower loop.
server_characteristics (object)¶
Controls power and airflow profiles for servers (CPU and GPU). Defaults and fallbacks are described below.
CPU Profile¶
The system’s default CPU profiles are [130 W, 10 W], [110 W, 10 W] and [170 W, 10 W]. If the DEFAULT_CPU_POWER_CHARACTERISTICS array is omitted entirely, the loader falls back to the HP PROLIANT profile.
GPU Profiles¶
The system’s default GPU profiles are P100 and A6000. If the DEFAULT_GPU_POWER_CHARACTERISTICS array is omitted entirely, the loader falls back to the V100 profile.
