Denmark alone, which is a relatively small country, has 1.3 billion Euros reserved to build out FTTH.” Van Melsem adds, “When it comes to FTTH, investments can be easily upgraded when takeup rate goes up. Main- tenance is cheaper, and the use of preterminated blown fiber reduces the amount of labor and specialized skills required.” The FTTH market in the U.S., however, does not offer as much growth potential. “Incumbent service providers like Verizon are not bending over backwards to put in blown fiber,” says Templeman. “The cost models in Europe don’t nec- In Europe, blown fiber is a popular means of bringing fiber to the home, which means that a fiber-optic system sometimes must travel through difficult terrain.

Emanuel County includes Swainsboro and seven surrounding communities located in east-central Georgia, 90 miles west of Savan- nah. Here in this rural area, a county school district believes a strong educational program in each of its eight schools is the foundation for a thriving and progressive community. Even more unexpected is the district’s forward-thinking approach as it embarks on the installation of a new district-wide network capable of supporting 10 Gigabit Ethernet (10GbE) and today’s most advanced network technologies. Years in the making Originally implemented in the mid 1990s, the network serving Emanuel County’s schools included a mix of Category 4, Category 5, fiber, leased T-1 circuits, and 10-Mbit/sec switches that by 2004 no longer served the needs of students and faculty. “Every time we needed more connectivity, we would add another low-end switch,” says Jerry Stefansen, former director of technology who stayed on as part-time project consultant for the district, following retirement in 2005. “We ended up with too much cabling and dai- sy-chaining that eventually became a huge wiring night- mare.

U nder the direction of the Federal Communications Com- mission, the Universal Service Administrative Company (USAC) administers the Schools and Libraries Program of the Universal Service Fund, commonly known as “E-Rate.” The E-Rate fund provides discounts to assist most U.S. schools and libraries in obtaining affordable telecommunications services. Funding, ranging from 20 to 90%, depends on the level of poverty and urban/rural status of the specific population being served. It covers four categories: telecommunications services; Internet access; internal connections; and basic maintenance of internal connections. To apply for E-Rate funds, applicants must first prepare a technology plan to demonstrate clear goals, a professional development strategy, needs assessment, required budget, and evaluation process. Once the plan is approved, applicants complete a Form 470 to describe the specific products, services, and functions being requested. “Instead of a formal bidding process like you have in the commercial marketplace, the E-Rate Form 470 becomes a worldwide RFP [request for proposal] that anyone can read and Systems & Solutions Inc.’s Avery Hinson, RCDD, and Arvin Weaver, lead respond to,” says Jerry Stefansen, former director of technology technician, check some of the 2,400 Augmented Category 6 connec- and part-time project consultant for Emanuel County School tions meant to support 10-Gigabit Ethernet transmission.

A deep floor with no restrictions. “Use a 4-ft. raised floor when possible,” he says. “Make sure it is above water-level grade and include subfloor drains. Provide plenty of room for cables, power equipment, and serviceability.” 2. Build a high ceiling into the data center. While a standard practice in many areas can be six feet in height, Evdoki- mo recommends 12- to 14-ft. ceilings. The benefit, he explains, is that “the heat can go across the room and stratify.” A downside of this approach is that the data center will have more open space to fire-protect, meaning more volume ________ to cover with expensive fire-suppression gases.

When you can use free air, and maintain complete isolation between supply air and return air, you can start delivering air in the mid-70s.” Peeling back the layers While the cause of near-crisis heat generation in today’s data centers is fairly straightforward, the means by which to address the problem is many-layered and has not come close to achieving con- sensus among industry thinkers.

Historically, the return-on-investment for water side economizers for data center applications has been a hard sell in most geographic areas. Chiller plants typically need to keep water at 42°F to deliver 55°F supply air and assuming a 5°F approach temperature, the economizer would only take over for the chiller plant when the temperature dropped below 37°F. With the supply air temperature allowed to creep into the 70s°F, however, then the condenser water can run around 55°F and with a 5°F approach temperature; the economizer can kick in whenever the temperature drops below 50°F. At that temperature, data center operators in most areas of the country would have access to significantly more “free” days of cooling. In fact, Intel reported a $144,000 energy savings for a medium-sized data center in the Pacific Northwest that depended Employing the strategy of isolating supply air from return air can provide an economical path for making incremental density increases. first on the effective return-air isolation to allow higher supply-air temperature.

Five- megawatt data center tenants, in eight different geographic areas, found significant cooling-cost savings versus a benchmark facility with standard open hot aisles and cold aisles, using chilled-water computer-room air-conditioning (CRAC) units with water economizers. The McKinstry study also looked at various options for improving the total efficiency of the standard data center open hot-aisle/cold-aisle arrangement compared to the fully isolated arrangement at various levels of loading, and found the segre- gated supply-air and return-air models delivered lower operating costs than all other combinations. While the variations between regions can be extreme, the chart of average HVAC operating costs (page 48) nevertheless provides an accurate view of the relative operating econo- mies of the different systems. The “base” data center employs chilled-water CRAC units with water side economizer, with the room arranged according to hot-aisle/cold-aisle best practices. Option A employs chilled-water air handlers with air side economizer and stream humidifier, again with hot-aisle/ cold-aisle best practices.

For example, it is claimed that closely coupled liquid-cooled solutions are more economical to implement incrementally, thus saving the cost of operating a full- blown data center cooling plant when a room is not fully built out. The McKin- stry Co. data suggest otherwise, however, with the extremely low operating costs for Option C when the space is less than 50% populated. In addition, lower operating costs in general have been central to the value proposi- tion offered for closely coupled liquid-cooled solutions, particularly as a rebuttal to objections over their significantly higher acquisition costs. In fact, the keynote address at this past spring’s AFCOM Data Center World (www.afcom.com), ___________ delivered by HP’s (www.hp.com) Christian _________ Belady, explained the power usage effectiveness (PUE) metric for measuring data center power and cooling efficiency (total data center power consumption divided by IT power consumption); it suggested a PUE of 1.6 was a measure of efficiency toward which the industry could aspire with closely coupled liquid cooling solutions. Compare this to today’s typical data center with a PUE around 3.0 and per- haps a 2.4, which can be achieved through implementing best practices in the hot aisle/ cold-aisle arrangements, or maybe even a computational fluid dynamics (CFD)-enabled 2.0 PUE.

They consume just less than 25 watts to support a maximum transmission distance of 30 meters. Greater service distances would require an additional electrical feed to power the copper adapter card, since the PCI-Express slot can only provide up to 25 watts. As with the 10-Gbit copper switches, the 10-Gbit copper server adapter card’s high power-consumption and cooling needs result in higher operational costs. To date, copper server and card adapter server manufacturers have demonstrated minimal interoperability with 10GBase-T switch vendors. Switch-vendor support is at least a year away due to power challenges. _____________________________________ In addition to the characteristics already detailed, optical systems can claim five attributes—extended distance ➤ 70 ■ September 2007 ■ Cabling Installation & Maintenance www.cable-install.com C Previous Page A Installation 7Maintenance Contents Zoom In Zoom Out Front Cover Search Issue Next Page EMaGS B F

OM3 50-μm fiber supports to operate compared to 10-Gig copper. 10-Gbit SFP+ optical transceivers will consume a maximum of 1.0 watt per port, compared to 10 to 15 watts per port for a 10GBase-T copper switch. 10GBase-SR server adapter cards typically use less than 9 watts to transmit up to 300 meters, while recently announced 10GBase-T cards use 25 watts to transmit up to 30 meters. Significant silicon-chip development will likely be required to reduce the power consumption of 10-Gbit copper interfaces. Although industry expectation is that silicon-chip power consumption may be reduced, the high insertion loss of copper cables at the extended frequency range needed to support 10-Gbit Ethernet and electronic DSP noise-reduction circuitry means that energy consumption will inevitably be higher than that of low-loss fiber inter- connects. The silicon-chip size-reduction work is not expected to be completed in the near future as major performance issues, such as electrostatic discharge (which impacts reliability), must be resolved. The power consumption of10-Gbit copper electronics and adapter cards will drive the need for excessive cooling, meaning greater energy use and running costs for data centers and possibly larger uninterruptible power supplies.
