Energy proportional data centers optimize power consumption

Posted in asset-utilization, data-center, data-center-network, dynamic-infrastructure, energy-proportional, google, low-power, power-utilization on July 7th, 2010 by FrankM – Comments Off

Google research looks to develop energy proportional data centers that throttle power based on network utilization.  The technique involves modifying the network topology and dynamically tuning network switches.  …

…   “the authors suggest several ways to build data center networks that use power in proportion to the volume of data being transmitted, rather than running at high-power during periods of both high and low utilization. ”   …

Juniper Networks creates data center network architecture to flatten legacy data center networks from three to two layers preparing the enterprise for future network fabric. …

… “Juniper’s 3-2-1 architecture helps customers simplify data center networks while simultaneously improving the economics and experience of IT and end users. Customers can now eliminate an entire layer of switching from their networks, delivering lower latency and higher performance, smaller footprint and lower power consumption, simplified management and lower total cost of ownership. By applying Juniper’s Virtual Chassis fabric technology to the access layer, Juniper eliminates the need for aggregation — a primary source of complexity in the data center network — and can reduce the number of switch interactions by up to 99 percent compared to legacy three-layer networks. It also improves application performance by reducing latency up to 77 percent compared to legacy three-layer networks. ” …
