    • Saving Energy With 'Smart' Cabling Mike Cooper, RCDD Systems Application Engineer, Netconnect Data Center Solutions mike.cooper@tycoelectronics.com October 31, 2007
    • Saving Energy With 'Smart' Cabling What is “smart” cabling? • High bandwidth cabling? • High density cabling? • Intelligent cabling? • Well designed cabling? Information is Tyco Electronics Confidential & Proprietary Do Not Reproduce or Distribute page 2 / October 31, 2007
    • Impact of Power Density • Power Density is increasing on average 15-20% per year within the data Center – Individual server power density – IT Technology refresh activity – Server footprint • Methods of measuring efficiency within the DC are outdated – Watts/sq meter are no longer useful in deciding server deployment strategies • Key to success is balancing infrastructure investments with IT goals model Information is Tyco Electronics Confidential & Proprietary Do Not Reproduce or Distribute page 3 / October 31, 2007
    • Power- Where is it Going? Reducing Data Center power consumption is a multi-faceted challenge. All areas need to be addressed to maximize data center compute capacity and minimize power costs. Netw ork Equip, 12% Server, 25% Cooling, 50% Pw r Loss, 10% Lighting, 3% Sources: EYP Mission Critical Facilities, Cisco IT, Network World, Customer Interviews, APC NOTE: Industry rule of thumb is that approx 25% of Data Center Power goes to networking equipment and typically includes cooling and power requirements.
