  1. Energy efficiency – in focus

  2. Design and Efficiency – DELL™ AX4-5 Power consumption: 345 Watt* Heat emission: 1535 BTU/h* Power consumption a TB: 38,3 Watt Heat emission a TB: 170,6 BTU/h * Manufacturer information, with maximum additional disks Energy efficiency – in focus

  3. Design and Efficiency – DELL™ AX4-5 Cooling system: • Power supply fan produces airflow • For each power supply there are two fans embedded in different places • Flat cooling elements Effect: • The airflow is divided inefficiently because cooling elements are covered by just one part of the airflow • In case of a single fan breakdown, second unit needs to compensate function. Result: Higher load to hardware Rear with ventilation holes Ventilation holes for the power supply Energy efficiency – in focus

  4. Design and Efficiency – HP MSA 20xx Power Consumption: 475 Watt* Heat emission: 1622 BTU/h* Power Consumption a TB: 39,6 Watt Heat emission a TB: 135,1 BTU/h * Manufacturer information, with maximum additional disks Energy efficiency – in focus

  5. Design and Efficiency – HP MSA 20xx Cooling System: • Power supply fan produces air flow • Intelligent air conduction between controllers and power supplies through the ventilation holes • Big cooling elements attached to the connection holes • For each power supply two redundant fans built in a row Effect: • Intelligent conduction of the air flow • In case on a single fan breakdown, no further power consumption therefore no expected hardware damages Open rear Ventilation holes for the power supply Energy efficiency – in focus

  6. Design and Efficiency – IBM DS3400 Power consumption: 361 Watt* Heat emission: 1235 BTU/h* Power Consumption a TB: 30,1 Watt Heat emission a TB: 102,9 BTU/h * Manufacturer information, with maximum additional disks Energy efficiency – in focus

  7. Design and Efficiency – IBM DS3400 Cooling system: • Power supply fan produces airflow • For each power supply two redundant fans embedded in different places • Very flat cooling elements • Memory looms into the airflow Effect: • Inefficient air division - cooling elements get covered by just one part of the airflow – however good positioning of the memory • In case of a single fan breakdown, second unit needs to compensate function. Result: Higher load to hardware Ventilation holes for the power supply Energy efficiency – in focus

  8. Design and Efficiency – FSC FibreCAT SX8x Power consumption: 475 Watt* Heat emission: 1622 BTU/h* Power consumption a TB: 39,6 Watt Heat emission a TB: 135,1 BTU/h * Manufacturer information, with maximum additional disks Energy efficiency – in focus

  9. Design and Efficiency – FSC FibreCAT SX8x Open rear Cooling system: • Power supply fan produces airflow • Intelligent air conduction between the controllers and the power supplies through the ventilation holes • Big cooling elements attached to the connection holes • For each power supply two redundant fans built in a row Effect: • Intelligent and effective air conduction • In case on a single fan breakdown, no further power consumption therefore no expected hardware damages Ventilation holes for the power supply Energy efficiency – in focus
