Shut down ghost servers, save energy.

For data centers that manage device switches, unplugging certain devices will bring significant energy savings to the enterprise. In an effort to draw attention to this issue, known as "Ghost Servers", uptime held a game in which they invited data center managers to submit their results of efficiency work, which was very impressive. In Uptime's game, Barclays, the best performing, removed 9124 physical servers last year. These servers consume a total of 2.5 MW (MW) of power and require 588 server racks. If these systems continue to operate, the company's electricity bill will be 4.5 million dollars higher. In addition, in terms of traditional hardware maintenance costs, the Barclay company saved 1.3 million of dollars and freed more than 20,000 network ports and 3,000 San ports. Sun Life Financial ranked second, and the company eliminated 441 servers, replacing 54 systems with newer, more efficient memories, and turning 75 servers into virtual servers. Sun life is expected to save 115-kilowatt of its electricity consumption each year, as well as 100,000 of dollars in energy costs. This change will also allow the company to release more data center space. Uptime this test to draw attention to the conservation of data center energy. Scott Killian, vice president of Uptime's energy project, was previously the manager of AOL's main data center and has been involved in a similar shutdown of unused servers. He said the process was not easy. When business units add new applications, IT operations will purchase and install servers to meet these requirements. Over time, the use of the application will move or disappear, making many servers useless. The business unit may be driving this expansion, but it operations are really creating this problem, they are not concerned about the hardware has lost its usefulness or inefficient, IT operations are fully control of data center space, ground space and energy. Shutting down invalid servers is a lengthy process that involves the interests of it and the business sector, and they may be more concerned with developing new products than removing old ones. In addition, this process may involve moving applications to virtual platforms and private cloud [note] environments. It's hard to know how IT managers consolidate and remove devices, but one metric is the sales revenue for the server. IDC points out that server consolidation is one reason for server revenue to fall. Barclays plans to continue its work in this area. In a statement, Ian Penny, the company's global head of distributed technology, said that the increasing number of virtualization and private cloud technologies has enabled us to continue to remove physical servers from the environment, resulting in significant savings and reduced environmental impact. "As we deploy the next generation of cloud computing platforms and start using the hybrid cloud model, we expect this trend to continue," said Penny. ”
