Energy-saving switches and servers: Environmental protection is a popular trend or a real value.

The term organic is probably the most widely used in the food industry, but green it is also used frequently. But unlike green-food advocates, not every IT professional buys it products because of the environmental benefits. The IT industry is increasingly focused on it environmental protection, and it is now becoming easier to find some energy-efficient switches and servers that can help businesses cut back on unnecessary energy consumption. While many companies are willing to choose products that may reduce their spending, the adoption of environmentally friendly products can also add a certain cost. It organizations should consider the size of their environment and total cost of ownership before deciding whether green networks are right for their company. Randstad US network manager Forrest Schroth said: "Under the same conditions, it must pursue environmental protection, but must not simply because of environmental protection and buy some products that do not help the company's business, this is asking for trouble." "How much does it want to save energy for the switch?" Green networks do not immediately save corporate money. Energy-saving switches and routers are usually more expensive. Richard Siedzik, director of computer and communications services at Bryant University in Rhode I. Smithfield, USA, points out that while the price is higher, energy efficiency is highly prioritized when selecting data Center network components. "We are proud that we are not only managing the availability of infrastructure, but also managing energy efficiency," Siedzik said. This will definitely add some upfront costs, but when we buy the product, we also take into account the cost of ownership throughout the lifecycle-including initial inputs, maintenance, and energy. He points out that the green network is not just about energy efficiency. In addition, he uses software to perform energy monitoring, measurement and management functions, including Cisco's EnergyWise energy management and power consumption software. Cisco recently integrated EnergyWise Energy management software into its switches, merging the products of Joulex, an energy management provider. Eric Hanselman, chief analyst at 451 in New York, USA, says the EnergyWise software in Cisco switches allows hardware to intelligently reduce power consumption and even enter "sleep mode" during idle hours. Server and System management vendors can also play a role in this area. "Our IBM servers can intelligently choose to reduce energy consumption at low usage rates," Siedzik said. "Siedzik and its team also use other vendors ' software applications to track energy metrics and trends. When considering a green IT strategy, enterprises need to pay attention to total cost of ownership. Randstad's Schroth said: "I would love to have a hybrid car, but in many cases, the car could be expensive, problematic and poorly performing, depending on the needs of its own use." I'm worried that things get complicated and put in more money, but I don't get the return on investment.。 He noted that it would be a waste to completely replace existing hardware in order to use an energy-saving switch to achieve a green environment, but it is a good strategy to increase the device in accordance with the cycle of hardware usage-without disrupting the operation of the data center. He said: "Green network is a very good ideal, which I think the industry should pursue the goal." He noted that it would be a waste to completely replace existing hardware in order to use an energy-saving switch to achieve a green environment, but it is a good strategy to increase the device in accordance with the cycle of hardware usage-without disrupting the operation of the data center. He said: "Green network is a very good ideal, which I think the industry should pursue the goal." "Suppliers: Open computing has brought green network methods and advantages to many network equipment vendors to consider energy efficiency as a priority for their data center products." Martin Hull, Arista Networksy Senior product line manager, points out that the company has been focusing on energy efficiency in designing products from the start of the company. In considering energy efficiency issues, the first step is to make the switch flexible enough to accommodate the datacenter refrigeration strategy. Arista and other suppliers have begun to discard emissions from the side of the equipment. Instead, their devices take a front to rear or back to front airflow pattern, so it has the flexibility to schedule the switch installation location. Hull points out that Arista is also designed to focus on reducing components. The core part of the switch is the special integrated circuit (ASIC) of the network chip. Arista and other vendors use the Broadcom chip, which contains a smaller number of ASIC, but has high performance, throughput, and features in managing power consumption. Energy-saving switches are important, but they are part of a large green data center strategy that includes many servers. Unlike servers, switches and routers cannot be closed when they are idle. They must remain on standby and are ready to receive and transmit traffic. However, Tony Harvey, the unified Computing System, UCS product Manager at Cisco's Data Center division, points out that idle servers can be a waste. "Companies need to process resources for peak capacity allocations, but that means they won't be fully utilized for most of the time," he said. Cisco has added features to its UCS platform that allow data center professionals to quickly switch to a server task. The UCS platform can also optimize other components, such as fan speed, to match the requirements of network hardware without consuming too much energy. Green networks involve more than servers and switches. Optimizing the entire data center-including cooling methods, energy sources, and rack design and replacement-can help businesses improve energy efficiency while maximizing returns from their hardware. Open Compute ProjectFacebook launched the goal of developing and sharing efficient server and data center design, which is a widespread response in the IT industry, with many large companies and suppliers such as Microsoft and Rackspace participating in the project. Open computing has also recently extended to data center switches. Facebook points out that its newest data center in Oregon State Prineville in the United States uses an energy efficiency model based on open computing design. It uses external air to cool it-and other natural-resource-saving technologies. The Praiville data center runs at a slightly higher temperature-energy efficiency of 30% higher than that of Facebook's previous data centers, which can save on cooling costs, says Omar Baldonado, a Facebook network engineering team manager. "Over the past three years, our data center operating costs have saved US $1.2 billion," he said. "Open computing projects encourage companies to share their data centers and green network best practices." Baldonado points out that while starting from a new environment is the easiest way to adopt a green network strategy, many organizations are turning to the cloud environment or starting to adopt virtualization technologies that can reduce the difficulty of improving energy efficiency. Randstad's Schroth said: "If you are going to build a data center now, then my construction method will certainly be more environmentally friendly than 13 years ago." Energy efficiency will be a major concern for us when replacing components. ”
