2 Background Rapid growth in the last few years caused space, power and cooling problems Rapid growth in the last few years caused space, power and cooling problems Increasing capacity for RHIC/ATLAS and other activities cannot be accommodated with current facility infrastructure Increasing capacity for RHIC/ATLAS and other activities cannot be accommodated with current facility infrastructure Search for additional data center space began in 2007 Search for additional data center space began in 2007 Update of talk originally given at HEPIX in St. Louis (Nov. 2007) Update of talk originally given at HEPIX in St. Louis (Nov. 2007)

21 New Data Center Layout

22 Where We Are Today (1) Data Center Expansion (part 1) is similar to existing facility Data Center Expansion (part 1) is similar to existing facility 12-in (30.48 cm) raised floor12-in (30.48 cm) raised floor Redundant cooling capacityRedundant cooling capacity No support for racks > 10 kWNo support for racks > 10 kW No support for supplemental coolingNo support for supplemental cooling Cable trays for power and networkCable trays for power and network Data Center Expansion (part 2) was designed for high density equipment Data Center Expansion (part 2) was designed for high density equipment 30-in (76.2 cm) raised floor30-in (76.2 cm) raised floor Support for racks > 10 kW (blades, half-depths, etc)Support for racks > 10 kW (blades, half-depths, etc) Redundant cooling capacityRedundant cooling capacity Support for racks > 2,500 lbs (1,135 kg)Support for racks > 2,500 lbs (1,135 kg) 13-ft ceiling (4 m) for high-profile racks13-ft ceiling (4 m) for high-profile racks Cable trays for power and networkCable trays for power and network Support for supplemental coolingSupport for supplemental cooling Environmentally-friendly buildingEnvironmentally-friendly building

23 Where We Are Today (2) Facility expanded from 5000 ft 2 (465 m 2 ) to 13,600 ft 2 (1260 m 2 ) of floor space Facility expanded from 5000 ft 2 (465 m 2 ) to 13,600 ft 2 (1260 m 2 ) of floor space Equipment capacity Equipment capacity from ~150 to ~300 racksfrom ~150 to ~300 racks from 6 to 13 robotic silosfrom 6 to 13 robotic silos Infrastructure support Infrastructure support from ~1 to ~2.0 MW of UPS-backed power (up to 4 MW capacity)from ~1 to ~2.0 MW of UPS-backed power (up to 4 MW capacity) Cooling capacity grew from ~1 to ~ 2 MW (up to 4 MW capacity)Cooling capacity grew from ~1 to ~ 2 MW (up to 4 MW capacity) 3 robotic silos and 6 racks of worker nodes first occupants of CDCE (October 2009) 3 robotic silos and 6 racks of worker nodes first occupants of CDCE (October 2009) Is this sufficient until 2018? Is this sufficient until 2018?

24 Unresolved Issues Insufficient funds to: Insufficient funds to: add 2 nd flywheel UPS for CDCEadd 2 nd flywheel UPS for CDCE diesel generator to support additional flywheel UPS unitsdiesel generator to support additional flywheel UPS units install additional 1 MW of cooling capacity (equipment already purchased)install additional 1 MW of cooling capacity (equipment already purchased) Estimated cost is additional US $2-3 million Estimated cost is additional US $2-3 million Estimate CDCE will exceed 2 MW of UPS power and cooling by 2012Estimate CDCE will exceed 2 MW of UPS power and cooling by 2012 Lead time to approve funds and pre-installation is 12 months  decision by 2011 Lead time to approve funds and pre-installation is 12 months  decision by 2011

25 Reason for Optimism? Multi-core cpu’s and increasing storage density have helped restrain a feared unsustainable growth in power and space needs Multi-core cpu’s and increasing storage density have helped restrain a feared unsustainable growth in power and space needs Rack counts have not increased at the same rate as computing and storage deployments Rack counts have not increased at the same rate as computing and storage deployments Somewhat hopeful that continued technological gains will further restrain data center growth Somewhat hopeful that continued technological gains will further restrain data center growth

26 Summary Facility footprint nearly tripled since 2007 Facility footprint nearly tripled since 2007 Applied lessons learned in design of data center expansion (part 2) Applied lessons learned in design of data center expansion (part 2) Must increase cooling efficiency with new technologies Must increase cooling efficiency with new technologies Rack-top cooling unitsRack-top cooling units Rear-door heat exchangerRear-door heat exchanger Hot aisle containmentHot aisle containment Significant increases in power efficiency and technology (power supply, multi-core cpu, etc) is a positive development, but some unresolved issues remain Significant increases in power efficiency and technology (power supply, multi-core cpu, etc) is a positive development, but some unresolved issues remain
