There is no doubt that power consumption has been a problem for the Enterprise data center operation of the cost burden, the pursuit of power consumption has also driven the server manufacturers to develop more energy-efficient design. Compared with the x86 processor, ARM has many advantages, such as low power consumption, low cost, high execution efficiency, and extensive partner support, the introduction of the related server processor products and the deployment on the server. 　　And in 2012, the development of server based on ARM architecture is very strong. As early as last year, Hewlett-Packard announced the launch of the world's first Ubuntu 11.10 operating system of a ...

Guide: While Intel is grumbling about servers with ARM processors, the upstart-server chip maker Calxeda in the processor arena will not give Intel Sole power over the word. While Intel is grumbling about servers with ARM processors, the upstart-server chip maker Calxeda in the processor arena will not give Intel Sole power over the word. They must build an ecosystem of hardware and software partners who believe that Low-power 32-bit ARM server platforms can occupy a niche in the data center. In order to achieve this goal, ...

When looking for open source cloud computing service providers, companies with strong development capabilities or specific business applications tend to routinely avoid commercial cloud computing service providers. Open source cloud computing platforms such as Eucalyptus, OpenStack and abiquo are expected to succeed in building private cloud computing opportunities for companies. But some problems remain, such as how the Open-source cloud services provider can reflect its value. Who will pull the top? Can the Eucalyptus system win in the brutal competition with OpenStack? Open ...

Editor's note: As the two main open source cloud platform, OpenStack and cloudstack each have advantages. Cloudstack installation and deployment are very convenient, the OpenStack framework is relatively open and flexible, can be customized according to user needs convenient development and customization. In this paper, the blogger through its own OpenStack building company's private cloud platform of actual combat experience, OpenStack implementation of private cloud landing needs to comb, synthesize personal views and evaluation and share with readers. Work for some time ago, based on Openst ...
