Blade server power consumption huge restriction Internet application

Although the http://www.aliyun.com/zixun/aggregation/13737.html "> Blade server can provide a number of benefits to the data center, resulting in significant economic benefits, but users of the blade server has found many of its deficiencies, Mainly includes the huge energy consumption, the space utilization rate is not too high.




The
Blade server is a stand-alone server that supports high-density computing. Unlike previous stand-alone servers, blades share parts (such as monitors) with other blades to simplify management, unify cabling, and reduce the server's footprint in the data center. However, when the blade was first introduced, it did not take into account the impact on the data center. So before you deploy, you need to do some work on capacity planning and architecture development.





in the past three years, Cerner, which has been providing managed services for many hospitals, has been using blades in seven of its data centers, with almost 1200 blades currently in use. Cerner is deeply aware of the potential and risks of this technology. As for the advantages, blade servers allow companies to consolidate business systems and adopt advanced management tools such as virtualization technology, and blade servers, on the other hand, are notorious for consuming power and cooling resources in the data center.





consumes more power





A standard server typically requires a power supply of 120 volts. A blade server typically requires a power supply of 280 volts. Some data centers simply cannot meet this requirement.





provides managed services with a total of 500 blade servers, some in the primary data center, run by Intelenet, and others in another data center. Intelenet has just completed a "major power expansion project" to support blade servers. "The construction and power systems designed for the data center can provide a certain amount of electricity per square foot," the company said. Recent hardware changes, such as adding blades, have forced us to improve the infrastructure of this data center to support the growing power and cooling needs. ”





The company acknowledges that, almost two years ago, the Working Group encountered a problem when it first deployed a blade server. "We ran a data center that took into account a lot of power requirements, but we made a mistake when we bought the first blade server chassis." "The distribution units and cables bought by the working group are much larger than originally expected." This actually limits other devices that can be installed in the same cabinet as the blade server.




John Rowell, chief technology officer at the Opsource Company in California,
, said the lack of planned electricity supply would lead to increased costs. For a larger-scale server deployment project, users do have to become power management experts, or they will be cost-heavy.
