Network Equipment to study poslužiteljaNakon energy saving power to introduce management, server, storage and user access a flood of praise. At the same time, network equipment is also working to reach the energy saving server. HP ProCurve Networking products sector, “said Dale Cosgrove product manager, network equipment, stressing equipment last year, saving features, energy saving features Apple A1189 Battery for previous equipment has never been focused on consumption previše.Ukupna power, network server or storage infrastructure and can not be on the same level. Although in comparison with the switch, server consume more energy, but accounts for 15% of the net energy budget. Server has a sophisticated power management control, while the server is different network equipment must be willing to switch informacija.Truss network power consumption is high. Cisco Catalyst 6500 Series switches, switches for each power architecture 42U up to 2kW to 3kW. Cisco Advanced Services Group, said architect Rob Aldrich, Cisco Systems, the last large-enterprise level – nexus 7000 Series switches in the power of each architecture to 13kW. The structure of power switches generate 13kW of heat in most servers more money-mounted, so it is concerned about the chilling poslužitelja.Tvrtka market research Gartner Inc. analyst Rakesh Kumar said, compared to most data center server pair to power between 10 kW 8kW. Hewlett-Packard vice president and general manager of the main service equipment, said Peter Gross, the current average power of 4 kW for raku.Neki manufacturers have started to introduce the energy saving features, such as high power supply efficiency, variable speed fan cooling. But now the switch, energy management measures is very limited. Most of the idle switch in power consumption greater operating 40% to 60%. Aldrich said that if less than 40%, then skip work should be discounted. He said, “if the user can accept the delay, because otherwise you have to spend so much energy.” Cosgrove, however, that a greater increase in energy technologies predstoji.Učinkovitije only effective tehnologijePodrška will gradually improve in some areas associated with these. Cosgrove said: “As a new generation of ships products to the open market, they will have the following characteristics.” For example: @ A will be more modular application specific circuit integrated (ASIC) design to make the last to turn off the light from the LED board memory boards, which do not use components. @ silicon process technology to reduce leakage current, and gradually promote energy conservation through a generation The new chips. Cosgrove said: “In the end, we will let network equipment from the current daily consumption of 100 watts to 10 watts.” @ R & D is more efficient for energy saving software, software will be used less energy efficient CPU Dell Inspiron 500 battery energy sources and less. @ It has been designed to operate at higher temperatures, the equipment to reduce costs hlađenje.Na example, Cosgrove current HP ProCurve devices that can run safely at 130 degrees, the temperature higher than the goal of most data centers. He said: “As data center IT managers to be able to run at higher temperatures, and this should encourage this design. “higher temperatures may be affecting wiring within a single vendor there. However, the temperature 130 degrees before being held, particularly in data center rack, network equipment vendors to do in a mixed environment complete tests. Burton Group analyst Drue Reeves said: “When a group of servers sharing the next heat, no one knows the network equipment and other types of equipment will show you how.” analyzes each vendor’s current limited in their production opreme.Drugi Focus: to improve control in the energy field and precise control. For all of the data center, real power and temperature monitoring is key, but also improve the management bit. firm Accenture consulting practice engaged in Rockwell Bonecutter green IT, said: “If anything is not normal, you want to know before a disaster. software management will be configured for accurate identification of network devices such as IP phones configured link layer discovery protocol. Software automatically during the day or at certain times of day when the computer shut down after the relevant cut off for VoIP over Ethernet device napajanja.Drugi current examples are: in the day, and the surplus for the last edge on both routers, but in the evening, the network can be configured as a router in the regime of low-power sleep. Only when this is necessary, a router will probuditi.Cosgro said: “These types of programs is saving opportunity.” High standards and new normativiStandarda to provide support for energy efficiency in the network is idle, to assist in measuring the energy efficiency of competing products. Energy efficient EthernetEmerging IEEE P802. 3az energy-efficient Ethernet (EEE) devices, the standards project could in the case of HP Pavilion dv9000 Battery low usage rate of the maximum degree of reduction of energy consumption of network equipment. Ethernet equipment is currently awaiting transmission between two devices, even when the network is still the case when no data. Equipment to support EEE send periodic pulse, other times to shut up. In her free time, this technology can reduce energy consumption by 90%. “Cosgrove said that in large networks, it will save you a lot energije.Novi standard also allows the transfer of several modes. For example, 10Gbit switch, if circumstances permit, some ports may in 10Gbit per second transfer rate 1Gbit fell to second, said storage energije.Aldrich 2011 to support equipment standard Eee LANDrugi van tržištu.Virtualni new technology is PCI-SIG announced a multi-source I / O virtualization (MR-IOV) , her assistant to stay on the network interface card provides access to a common pool. With high speed PCI Express bus, which would essentially extend the PCIe bus outside server. Burton Group analyst Reeves said: “Instead of a server in each network card, you will see pairs of cards. You can use the tool vendor specific server in a server of these cards have been part of the permeability network card. “Energy will increase utilization of the network, which is a virtual network card bandwidth achieved by each segmentation. He said technology that allows only a few network cards and switch ports. Reeves wise forecast product will be displayed first in učinkovitostKonačno 2012.Energetska, standardization of measurement of energy efficiency began to emerge in a number of network devices. For example, Juniper Networks products provide some of its rate of energy consumption (ECR) form of data. ECR is a draft standard, proposed by the ECR initiative. Lawrence Livermore Laboratory, Ixia and Juniper to improve the specification, measurement and network equipment communication for every unit of energy and Juniper performansi.Cisco now also started to support the telecommunications industry to EU standards (ATIS) IBM ThinkPad T60 battery energy efficiency rating of telecommunications (Teer) specifications. Specification of ATIS in dana.Ali year pass any rule is not universally accepted. While ECR Juniper support, but not all of their forms of data production are included in the evaluation efficiency. Cosgrove said that because HP can not understand the move of consumers, HP data in the form of its products do not contain these two standards of energy efficiency. He said: “Consumers are concerned about the power of a large number of solutions.” Cosgrove said currently there still exist outside the norms opposition, opponents conclude that the lack of detailed and transparent system of scoring. This means that manufacturers can choose to meet their needs posjetitelja.Do end of this year, to be truly transparent flow rates. Koha , EPA standards, the biggest network equipment energy star rating will be published. Prior to last December, EPA Energy Star specifications developed for small network equipment network print specifications of major equipment will cover most of the Spokesperson enterprise network opreme.Prema EPA said the plan to go out in June 2010 draft standard in data centers, announced in late 2010, data based on standard network equipment project. Cosgrove said the new rules would include such as power supply, internal chips energy-efficient and other components, as well as Ethernet and total energy consumption of the equipment, it will become an important future energy standards učinkovitosti.Za network administrators ensure energy efficiency is the easiest way to buy new equipment, but in reality it is a gradual process, because the administrator must update old equipment to measure the costs and benefits of potential energy between the report.
