钣金加工对钣金密度硬度有什么要求?性价比

密度与低密机柜钣金加工工艺大不相同,我们下面用简单明了的数据和图表来展示其中钣金加工特性不同,方便各位同仁参考。

在数据中心建设中,似乎总会面临「To be, or not to be」迷局。谁都知道,在数据中心偶面积方面基本是寸土寸金,想有效的利用空间面积,采用高密度机柜布局似乎是一个不错的选择, 可以总是会有专家出来告诉你一组“可怕的数据”: 最新的刀片式服务器机架功率15kW,台式服务器机架功率1.5kW,模块式服务器机架功率5kW。高耗电必然产生局部高温,它使温度梯度变化变大,通风降温变成一个不可能完成的任务。

Density and low density cabinet sheet metal processing technology is very different, we use simple and clear data and chart to show the different features of sheet metal processing, to facilitate the reference of colleagues.

In the construction of data center, it seems that To be or not to be always faces the puzzle. Everyone knows that the area of the data center is basically an inch of gold. To use the space area effectively, the high density cabinet layout seems to be a good choice. There will always be an expert to tell you a group of "terrible data": the latest blade service rack power 15kW, the desktop server rack. Power 1.5kW, modular server rack power 5kW. High power consumption inevitably generates local high temperature, which makes the temperature gradient change larger and ventilation cooling becomes an impossible task.

采用高密度机柜的优势

可是高密度机架带来的好处是显而易见,至少可以获得更高的运算能力和可用度。另外一个挑战来自于安全成本(例如:烟雾报警器/平方英尺),但是它并不会致使高密度产生明确的费用。此外,对较高密度给予预期的高水平监测将抵消上述不利因素。

Advantages of high density cabinet

However, the advantages of high-density rack are obvious, at least it can get higher computing power and availability. Another challenge comes from safety costs (e.g. smoke alarm / square feet), but it does not cause high density to produce a clear fee. In addition, the high level monitoring of higher density will offset these disadvantages.

低密机柜就一定节约费用吗?

在低密度空间内,照明的成本更大。在大于18,000平方英尺的空间需要1.6千瓦/平方英尺的照明。增加的维护费用在一定程度上也导致了成本的增加。

Will the low density cabinet be sure to save the cost?

In low density space, the cost of lighting is greater. In the space greater than 18000 square feet, 1.6 kW / sq ft of lighting is needed. Increased maintenance costs to some extent also led to an increase in costs.

高密机柜与低密机柜费用对比

IT设备在总预算中占据很大部分。下图列举了高密机柜与低密机柜在CFD设计成本、照明成本、IT设备(机柜)、冷却成本、以及总拥有成本等方面的费用对比。

Comparison between high density cabinet and low density cabinet

IT equipment occupies a large part of the total budget. The following figure lists the cost comparison between high density cabinet and low density cabinet in CFD design cost, lighting cost, IT equipment (cabinet), cooling cost, and total cost of ownership.

云立方在设计架构上,非常注意箱体内的空气流动。为了获得更好的气流分布控制。“宝贵”的冷空气必须被输送到继续降温的地方。同时,云立方为了处理更高的热负载密度,制冷容量可以随IT负载的变化而变化,不仅提高了制冷效率,而且有效地节省了能源。实现了TCO(总拥有成本)的有效降低

由此可见,高密度的集装箱数据中心的成本更低。在上述样例中,总共节省5,200,000美元,或者一年的用电费用。

Cloud cube pays great attention to air flow in the box. In order to get better control of airflow distribution. "Valuable" cold air must be transported to continue to cool down. At the same time, in order to deal with higher heat load density, the capacity of the cloud cube can change with the change of IT load, which not only improves the efficiency of refrigeration, but also saves energy effectively. Effective reduction of TCO (total cost of ownership)

This shows that high density container data center costs less. In the above example, a total savings of 5200000 dollars or a year's electricity cost are saved.
