Lieden: Efficient power management to create a green "cloud"

Power is an important core of cloud computing
Cloud computing is in full swing, local governments attach great importance to cloud computing, and there are a lot of cloud-related projects under construction. Take the Chongqing municipal government as an example, recently spent nearly tens of thousands of dollars invested in the two Rivers International and Jiangjin District two large International cloud computing Center, its goal is to build up to accommodate millions of servers, the value of hundreds of billions of dollars in the size of the cloud computing base, highlighting the local government in IT information construction strength and courage.
We've seen a lot of discussion about cloud computing, but from the increasingly tense management of energy consumption, we should recognize that there is another important core of cloud computing: power Management in the data center.
We've invested in a lot of data centers, why aren't these data centers enough to be a cloud computing hub? Not all of these data centers are not able to provide IT services externally, in fact, IaaS, PAAs, or SaaS, data centers can provide, they and the cloud computing center, a very important difference is the efficiency and energy costs. With the help of virtualization technology, Cloud computing Center can make full use of computing resources, network resources and storage resources, with the help of desktop virtualization technology, can also extend it to the PC access side. At the same time, the cloud computing Center is a large number of green energy-saving technology, its core is to reduce energy costs, reduce operational costs. On this basis to build on the cloud computing services, will be in price, stability, reliability of competitive strength, and all this is inseparable from power management.
Today more and more users are concerned about the energy consumption of data centers. According to authoritative statistics, power consumption in data centers has accounted for 8% of global energy and power consumption, and, more frightening, the power consumption of data centers is growing at a rate of doubling every 3 years. In the annual IT investment cost of the user, the operation dimension cost is far exceeding the purchase cost of IT equipment, and the power consumption has become the user's pain point.

To strengthen power management from the "fine"
for how to strengthen the cloud Computing data Center power management, specific problems or specific analysis, which, the detailed electricity data is a key. 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?
In this area, the United States Raritan (Lieden) has shown a keen insight into the power management of data centers. "Many companies want accurate, continuous power monitoring to capture the core of the power problem, such as finding ways to reduce energy costs, cooling the racks effectively, and optimizing capacity, and looking for advanced remote switch switching and power sequencing capabilities, and that's what we're aiming at." "Raritan Lieden CEO Xu said.
According to Xu, the rapid development of energy consumption in data centers is not a normal result of industrial development, but is caused by unreasonable planning, design and use. Take refrigeration For example, cooling every 1W power consumption, at least can take away the heat generated by 3W IT equipment. But in the practical application, the excessive refrigeration is the widespread problem, the domestic most data center's pue is above 2.6, even then, the local hot spot causes the data center fault to occur frequently.
to make rational use of resources, a high level of power management is essential. To curb the rapid growth of power consumption, we need to have a clear understanding of the basic data, the more detailed the better. But in the past, data center power management is too extensive, data center pue too high, because there is no detailed power data support, it is difficult to find problems, not to mention targeted solutions.
in Lieden Strategic planning, PDU, IPDU, and Power IQ management software have become the company's new strategic focus. Through these products you can clearly understand IT equipment, PDU Export Group, rack, branch circuit power supply, current, voltage, temperature, humidity and other basic data, so as to help managers improve the data center power supply effectiveness, strengthen capacity planning, improve the efficiency of energy utilization, make efficient power management green "cloud" to achieve.
