How does DCMI help cloud computing centers manage computing resources?

  with the rapid development of the Internet and communications industry, especially as cloud computing becomes a new IT service model and accepted by more and more enterprises, the data center begins to move toward the cloud computing center step in the direction. At the same time, the new generation of data centers on the number of servers more and more demanding, a data center owned servers usually need to reach more than 1000 to 10,000 units. With the transition of data center to cloud computing Center, when more servers are assembled, how to effectively manage the data center to achieve efficient energy saving will be the problem faced by more and more data center supervisors, which has been making unremitting efforts for the related IT vendors. The

    Intelligent Platform Management interface (Ipmi,intelligent Platform Management Interface) is Intel's important contribution to platform management, However, IPMI is a relatively granular management, facing the future of high-density data center management specifications, faced with the dilemma of high cost. In this situation, Intel adapts to the development of technology and the needs of customers, the introduction of DCMI (Data center manageability Interface), the Datacenter management interface, to solve the above problems.

    DCMI is a set of server platform management interfaces specifically for IPDC (Internet portal data Centers, Internet portals) and other high-density data center deployments. The establishment of this interface standard plays an important role in reducing the management cost and improving the operation efficiency of the data center in the future. Experts believe that in the era of cloud computing, in the demand for high-density server clusters increased today, the DCMI standard will be a significant development and full application.

    In fact, DCMI is not a specification that was recently developed, and Intel issued a formal version 1.0 specification as early as May 1, 2008. It's just that it becomes more important as the role of the data center changes. The development of DCMI
has also been supported by well-known IT companies such as Dell, Fujitsu and HP.

    dcmi and IPMI relationships  

    Prior to the launch of DCMI, Intel had IPMI, Used to standardize the management of servers in the datacenter. The IPMI specification at the time was version 2.0, designed to cover many types of server management scenarios, so many of the optional features do not apply to high-density data center management. In addition, the IPMI specification does not provide a high density data center with the requiredThe required set of functions. In short, the IPMI specification does not meet the required needs of high-density data centers, and the full IPMI 2.0 functionality goes beyond these requirements. Therefore, the implementation of IPMI is faced with an awkward situation, and there are significant differences between vendors. Many high-density data center customers are also refusing to adopt the IPMI 2.0-based system as a common solution.

And Intel's in-depth discussion with several key high-density data centers and portal data Center customers has created a common feature that high density data center customers seek: streamlining, interoperability, openness, reliability, simplicity, stability, and low cost. To this end, Intel chooses the IPMI (Intelligent Platform Management Interface) 2.0 specification as a pointcut, based on IPMI 2.0, to create a specification that clearly defines the necessary features and interfaces for a range of data centers. This is followed by an extension of IPMI 2.0 with the functional areas that are not covered by the IPMI specification and that are required by high-density data centers, resulting in the DCMI 1.0 specification.
