Google Data Centers Measure 2011 PUE at 1.14

Google announced that its trailing 12-month average PUE (power usage effectiveness) was approximately 1.14 -- an improvement from 1.16 in 2010. PUE is a ratio of the total power used to run a data center to the amount used to power the servers.

Google said its calculation includes everything that contributes to energy consumption in its data center -- not just power for servers and cooling systems. It also includes heating/cooling for the office, system inefficiencies like transformer, cable and UPS losses and generator parasitic energy draw. Otherwise, the number would have been even lower.

Comcast Business Launches Cloud-based Unified Communications

NTIA Spectrum Report Proposes Sharing 1755-1850 MHz Band

The National Telecommunications and Information Administration (NTIA) issued its long-awaited report on reallocating spectrum currently occupied by the federal government for commercial purposes.

The "Assessment of the Viability of Accommodating Wireless Broadband in the 1755 – 1850 MHz Band" finds that 95 megahertz (MHz) of prime spectrum could be repurposed for wireless broadband use. Over 20 federal agencies currently hold more than 3,100 individual frequency assignments in this band. Federal uses of this spectrum include law enforcement surveillance, military tactical communications, air combat training, precision-guided munitions, weather balloons, etc.

Clearing a spectrum band of federal users requires finding other spectrum for these applications, as well as the cost and migration challenges in deploying new equipment. The NTIA estimates it may take a decade to complete a migration.

In addition, NTIA said its analysis of the cost of a complete relocation raises questions as to whether the proceeds from auctioning the 1755-1850 MHz band for commercial use will exceed federal relocation costs, as required by law.

Therefore, NTIA is proposing NTIA proposes a spectrum sharing scheme between government and industry.

"Spectrum is a finite resource in growing demand, and we need to focus on new ways to maximize its use. By working with the FCC, other federal agencies, and the industry, we can make more spectrum available to fuel innovation and preserve America’s technological leadership while protecting vital government missions,�? said Assistant Secretary for Communications and Information and NTIA Administrator Lawrence E. Strickling.
  • In November 2010, National Telecommunications and Information Administration (NTIA) recommended that 115 MHz of spectrum be reallocated for wireless broadband service within the next five years. As part of the announcement, NTIA released two complementary reports detailing the effort to nearly double commercial wireless spectrum: a Ten-Year Plan and Timetable, as well as a Fast Track Evaluation identifying the 115 megahertz of spectrum to be made available within five years. In the Fast Track Evaluation report, NTIA examined four spectrum bands for potential reallocation within five years: 1) 1675-1710 MHz, 2) 1755-1780 MHz, 3) 3500-3650 MHz, and 4) 4200-4220 MHz and 4380-4400 MHz. The report recommends that various portions of these bands totaling 115 megahertz be made available for wireless broadband use within five years, contingent upon the allocation of resources for necessary reallocation activities. Specifically, NTIA recommends reallocating 1695-1710 MHz, currently used for dissemination of severe weather information and alerts via satellites operated by Commerce's National Oceanic and Atmospheric Administration, and 3550-3650 MHz, which would be shared with Department of Defense radar systems mainly on ships. NTIA recommends some geographic limitations on the availability of these bands to prevent harmful interference to government facilities in the 1695-1710 MHz band and to the proposed commercial services in the 3550-3650 MHz band.

  • In June 2010, President Obama signed a Presidential Memorandum committing the federal government to make available 500 MHz of federal and commercial spectrum available to new mobile broadband usage over the next 10 years. The effort, which would nearly double the amount of commercial spectrum currently available for commercial use, was expected to result new rounds of spectrum auctions.

GreenTouch Achieves Major Gains in Energy Efficiency for Optical Access

The GreenTouch Consortium, a global research initiative dedicated to dramatically improving network energy efficiency, introduced a major breakthrough for optical access -- Bit-Interleaved Passive Optical Network (Bi-PON) technology. GreenTouch estimates Bi-PON ultimately could deliver power reduction of 30 times over current technologies while improving performance and reducing cost.

In a webcast, researchers from Alcatel-Lucent's Bell Labs, France's INRIA research lab and France Telecom Orange, described how the bit interleaving passive optical network (BIPON) leverages a new protocol that cuts energy consumption in time division multiplexing (TDM) PON optical network units (ONUs) by a factor of 10 compared to today’s protocols. The key observation is that 99% of data is unnecessarily processed in ONUs today. By modifying the protocol, an order of magnitude improvement in ONU performance can be attained.

The bit interleaving protocol reduces energy consumption in the ONU by reducing clock speed requirements, data processing requirements, voltage requirements, and memory requirements. The bits are spaced in time to match the clock rate. The bit interleaving protocol frame structure includes a header and a payload section. The header contains a synchronization code word and a unique identifier for each ONU on the PON. The header also contains information that allows the ONU to know where its payload bits are — at what offset and bit rate they are being sent in the payload section.

The consortium members said Bi-PON represents the next major leap in passive optical network (PON) technologies. It is expected to be a necessity as electronic processing will increase with future 40GPON systems.

“With this demonstration, GreenTouch again shows why it is one of the most ambitious collaborative environments in sustainable network technologies,�? said Gee Rittenhouse, GreenTouch chairman. “We are committed to reducing energy consumption across all ICT networks and Bi-PON is a huge and critical step in helping us achieve that goal. The impact is clear and wide-ranging including wireless backhaul and fiber to the home. Implementing Bi-PON over current technologies will have the energy savings equivalent to the carbon impact of permanently taking all the cars in a city like San Francisco off the road. We are making great progress toward our goal and are planning to make advances like this across all of our 25 research projects that are currently underway.�?
  • In February 2011, the GreenTouch Consortium demonstrated a Large-Scale Antenna System proof of concept with the potential for tremendous energy savings thanks to its novel wireless transmission techniques. Such an antenna array, consisting of dozens of individual units, would transmit only one percent of the energy transmitted by a single antenna, for the same quality of service. Instead of broadcasting signals throughout the entire coverage area as other antenna systems typically do, the Large-Scale Antenna System utilizes knowledge of the propagation channels to transmit concentrated beams of information selectively to many users at once. The greater the number of antenna elements deployed, the higher the concentration of the beams and, therefore, the lower the power that any antenna needs to send a given amount of information.

Vantage Data Centers Awarded LEED Platinum Certification

Vantage Data Centers has been awarded LEED Platinum certification for its second Santa Clara data center (V2). LEED certification is offered by U.S. Green Building Council (USGBC) as a tool aimed at achieving high performance design and construction of buildings in areas such as human and environmental health.

LEED Platinum certification is the highest tier of LEED certification offered by USGBC.

“V2 is a highly efficient and highly engineered solution which meets the unique needs of our customer. It represents how Vantage is diverging further from an industry that has resisted innovation and that has forced tenants into ‘one size fits all’ products,�? said Jim Trout, Vantage Data Centers’ CEO. “What is also gratifying is that our customers share our passion for both operational excellence as well as continued commitment to minimizing their environmental footprint.�?

Vantage noted that all of its facilities have been constructed to meet LEED Platinum requirements.

In August 2011, Vantage announced their first data center, V3, had achieved LEED Platinum certification. Vantage’s third building, V1, is a LEED Platinum candidate and upon successful certification of this building, Vantage’s Santa Clara site will become the largest LEED Platinum data center campus in the U.S.
  • In February 2012, Vantage Data Centers reported that its V2 facility is delivering a Power Usage Effectiveness (PUE) of 1.12, making it one of the most energy-efficient data centers in the industry. V2 was constructed and leased two years ahead of Vantage’s original business plan and developed in close collaboration with the single tenant now occupying the building.
