After a one-year trial period, Intel has approved the idea of cooling servers by dunking them in mineral oil. Created by Green Revolution Cooling (GRC), the liquid cooling system, known as CarnotJet, removes heat from server electronics more efficiently than traditional air-cooling methods by submerging the servers horizontally into the bath of GRC’s GreenDEF mineral oil. Heat … [Read more...]
Simplified Data Center Rack Cooling Management
The C degree Flow™ strip from Telect simplifies the managing of data center rack temperatures and increases cooling efficiencies. Using the strip's inherent and bold color-shifting properties, a technician can easily assess data center temperatures and be assured that all is cool. Additionally, temperatures across a rack can be increased by knowing where the cold air is going, … [Read more...]
Server Failures Don’t Rise Along With the Heat
Researchers at the University of Toronto, who studied data on equipment failures at data centers operated by Google, Los Alamos National Labs, and Canada’s SciNet HPC consortium, conclude that the effect of high data center temperatures on system reliability is smaller than often assumed. For DRAM failures and node outages, no evidence for a correlation with higher … [Read more...]
Ten Common Data Center Surprises
Emerson Network Power released a list of 10 common surprises for data center and IT managers and offered tips on how to be prepared for them. Those high-density predictions finally are coming true: After rapid growth early in the century, projections of double-digit rack densities have been slow to come to fruition. Average densities hovered between 6.0 and 7.4 kW per rack … [Read more...]
Data Center Technology Controls Temp by Moving Software Workloads
Facebook is exploring a technology that controls temperatures in the data center by automatically moving software workloads among servers according to the air pressure on either side of each machine. The system uses a load balancer to shift tasks among servers based on their particular “cooling needs,” which are related to air pressure in the data center. The idea is to keep … [Read more...]
