What are these?
Conclusions
• Technologies to drastically reduce cooling infrastructure power consumption are now available.
• Alternate cooling technologies can provide significant reduction in water consumption.
• Cooling device innovation continues for conventional air cooled data centers
• Things are changing: – Allowable environmental limits are expanding
– Heat transfer closer to heat source
