The DoD said this week that it will convert one of its data centers to use a liquid cooling system from Asetek Inc. The move could clear the way for broader use of liquid cooling in high-density server deployments at the DoD, which says it will carefully track the efficiency and cost savings from the project.
Intel Unveils Low-Power Atom Chips for Servers - Intel’s first Atom server-class processor has arrived, and some major hosting companies say they’re ready to start filling their racks with servers using the low-power chips. Intel’s announcement is the latest milestone in the ongoing push to reduce energy usage in data centers, which has prompted server vendors to adapt low-power smartphone chips for the server market, including both Intel’s Atom and chips from ARM that are widely used in iPhones and iPads.
IBM Lights Up Silicon Nanophotonics for Big Data - IBM announced a major advance in the ability to use light instead of electrical signals to transmit information for future computing. Referred to as Silicon Nanophotonics, the technology allows the integration of different optical components side by side with electrical circuits on a single silicon chip, using sub-100 nanometer semiconductor technology.
Big Leases for Dupont Fabros in Santa Clara,Chicago - Wholesale data center provider Dupont Fabros announced this week that it has closed significant leases in multiple locations.
