The core of cloud computing: Power Management in data centers

The Government attaches great importance to cloud computing, there are many cloud computing projects around the world, the project scale is also relatively large. The Chongqing municipal government, for example, invested nearly tens of thousands of dollars to build the two Rivers International and Jiangjin District two large international http://www.aliyun.com/zixun/aggregation/13644.html "> Cloud Computing Center, the goal is to build a host of millions of servers, The value of hundreds of billions of dollars in the size of the cloud computing base, highlighting the government's strength and courage.

There is a lot of elaboration about cloud computing, but from the point of view of energy consumption management, the core of cloud computing is the power management of 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 able to provide IT services externally, and in fact, IaaS, PAAs, or SaaS, data centers can provide them, compared to the cloud computing center, the difference lies in 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 and competitive strength. All this is inseparable from power management.

As a leading manufacturer of KVM Systems, Raritan (Lieden) has a keen insight into data center management. "Our KVM products are widely used in many data centers around the world, we are familiar with data center management, and we understand the needs of data center users." "Raritan Lieden CEO Xu said.

Now, Xu says, users are increasingly paying attention to 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.

It should be pointed out that the rapid development of energy consumption in data center is not the normal result of industrial development, but 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." Xu said. In the strategic planning of Lieden, PDU, IPDU and Power IQ management software has surpassed KVM in its strategic position, and its growth momentum has surpassed KVM, becoming the new strategic focus of the company.

Xu says the level of data center management is always improving. Compared with competitors, Lieden's advantage is to focus more on the market, so that more clearly understand the needs of customers, according to customer needs timely response. From KVM to PDU to Dctrack are responding to market needs. Lieden, a third-party data center management vendor, will continue to play this advantage, he said. Focus will become the relentless pursuit of force.
