American force: Tame Runaway Energy "Mustang"

In the practice of data center, the user's cognition to PDU and IPDU is mainly in the function of remote restart. During the http://www.aliyun.com/zixun/aggregation/32593.html "> System operation, some unknown faults often occur and need to be resolved by reboot." This is prevalent in the Internet enterprise and gaming industry, and their system equipment is mostly hosted in IDC Room, which needs to be managed remotely. If these devices use a common power outlet, only the management of the trust service providers, the effectiveness and timeliness of the inevitable discount. By using PDU power sockets, especially IPDU power outlets, users can remotely manage devices and restart them easily. For large enterprises, the Management Branch office, also can use PDU and IPDU to improve the management level.

But with the development of data center, the role of PDU has changed very much, its core is in the management of power consumption. With PDU, IPDU, and management software, you can clearly understand the power consumption of IT equipment. For example, the Power IQ management software of the U.S. national company it enables managers to improve the effectiveness of data center power supply through a single Web interface that clearly understands basic data such as power, current, voltage, temperature, and humidity of IT equipment, PDU exit groups, racks, and branch circuits. Strengthen capacity planning and improve the efficiency of energy use.

The so-called enemy. By using PDUs, especially IPDU, you can clearly understand the power consumption of each of the IT devices connected by each power socket at each time period. Of course, the use of PDU equipment will increase the cost of building the data center. Therefore, some people questioned whether it is necessary to monitor each power socket, whether monitoring the PDU can be. In addition, users have pointed out that for power management is best to monitor only, if there is no PDU port for remote control, will be a single point of failure to reduce the reliability of the data center.

Standing in the local view, these views have a certain degree of rationality. Related to the level of management, specific problems or specific analysis. To virtualization as an example, which has a function is in the business trough, through the virtual machine migration, you can focus on a small number of servers, shut down the remaining physical machines, to achieve the greatest energy-saving effect. But in the concrete operation, need the data support. There is no clear understanding of the power consumed by each server. How can the corresponding management strategy be developed?

For a server, for example, the power of the processor is basically the same, but the performance varies widely. The Intel Next Generation processor is about 40% better than the previous generation. But from the processor power consumption, or to maintain the 100W or so. Even with the same power consumption, the new processor has a better energy-saving performance. The point is that the processor does not always work at full capacity, and the processor power consumption is dynamically changing. Therefore, at any time to understand the changes in equipment power consumption, the development of targeted management strategy is essential.

In the past, the data center power management is too extensive, the data center Pue is too high, because there is no detailed power data support, it is difficult to find problems, not to mention targeted solutions. Therefore, to the uniform has been electricity this runaway "Mustang", strengthen power management is an effective way. Perhaps it is to see this trend, the KVM system is known as the United States in the quietly, has shifted the focus to the power management, both PDU and Power IQ management software are placed high expectations.

The father of the KVM, Xu CEO of the United States, said, as a data center management of Professional manufacturers, the force is very good awareness and grasp the trend. According to Xu Qingyi, the current growth trend in power management products has gone beyond KVM, and Lieden has upgraded from a KVM system to a data center management solution provider with power management as its core.
