cooling - News, Features, and Slideshows

• Better chip-cooling with nanotubes

  University researchers have discovered a way to use nanotechnology to boil water very quickly. And that, they say, will help to more efficiently cool computer chips, leading to more powerful and smaller machines.

• Forum: Power worries a wake-up call for datacentres

  Worries about the reliability of our electricity supply and the danger of power cuts this winter are a wake-up call for datacentre operators to put their houses in order.

• Datacentre cooling a hot topic at panel discusssion

  Datacentre operators will go to almost any lengths to avoid an overheated server. Case in point: a financial institution in London suffered a power shortage during a very hot day one recent summer, and was left with no ability to cool its servers and storage.

• NZ datacentres 'irresponsible', says Revera chief

  Most New Zealand datacentre investment is irresponsible in terms of location, sustainability and management, says Revera chief executive Wayne Norrie.

• Revera builds cool next-generation datacentres

  Datacentre outsourcing company Revera has invested up to $10 million in new datacentres to capitalise on the move towards dense computing and virtualisation.

  Virtualization: Optimized Power, Cooling, and Management Maximizes Benefits

  IT virtualization, the principal enabler of cloud computing, can have significant consequences on the data center physical infrastructure (DCPI). Higher power densities that often result can challenge the cooling capabilities of an existing system. Reduced energy consumption that typically results from physical server consolidation may actually worsen the data center’s power usage effectiveness (PUE). Dynamic loads that vary in time and location may heighten the risk of downtime if rack-level power and cooling health are not considered. Finally, the fault-tolerant nature of a highly virtualized environment could raise questions about the level of redundancy required in the physical infrastructure. These particular effects of virtualization are discussed and possible solutions or methods for dealing with them are offered.
