华为UPS电源未来数据中心需求华为UPS电源未来数据中心需求 导读： 高效率、智能化的模块化UPS显然更符合未来数据中心发展的要求。据了解，目前模块化UPS年市场增长率超过6%，预计未来将会超过10%。而在最近结束的中移动集采中，模块化UPS作为独立标段，已占据120kVA以上容量段超过14%的采购份额。在电信行业，高频化、模块化已经成为UPS采购的主流趋势。 3 数据中心需要什么样的UPS 首先应该承认，不同行业对UPS的认知与应用仍存在巨大差异。各种方案的应用也因人而异，并无统一标准。但是在保证可靠供电的前提下，笔者认为未来的数据中心将会在以下几个方面对供配电系统提出更高的要求。 1）首先是“快”，即快速建设、快速扩容。 目前在数据中心的建设方式上，模块化的理念已逐渐被大家所接受。无论是模块化数据中心还是集装箱数据中心，都是这一理念的具体实现。模块化UPS同样符合这一理念。如果仅从整体部署速度来看，模块化UPS和塔式UPS差别并不大。但如果从后期扩容方面以及初期投资方面，模块化的优势都非常明显。首先，按需扩容的功率模块，更符合业务发展的需要。尤其是对于平均寿命只有3到5年的互联网企业，谁能早一天完成部署，早一天实现扩容，就能早一步赢得客户，早一步占据市场。相比传统塔式UPS一到两周的安装时间，模块化UPS只需几分钟即可完成扩容。其次，商业竞争日趋激烈，市场环境变幻莫测，以及未来发展的不确定性都要求CEO们必须在长期规划与初期投入之间寻找最合适的平衡点。模块化的结构只需要预留合适空间，而不需一次性投入，未来可根据业务发展分批分期投入，明显降低企业运营风险。对客户而言，无论是自建还是出租，模块化UPS都更适合企业的未来长远发展。 2）其次是“易”，即易用性、高可用性。 相比传统数据中心为保证可靠性而设计的复杂的Tire4架构、2N系统，旁路模式、市电直供+UPS备份等等“不可思议”的方案正在被互联网巨头们采用。正是虚拟化的技术实现，使得互联网企业从追求单纯的供电可靠性变成了更看重以快速维护代表的可用性。 因此UPS也要向IT设备一样易维护。这对UPS有两点要求：1、发生故障不能影响业务运行，即不影响正常电力供应；2、发生故障后要方便维护，最好运维人员可自行维护而无需联系厂家。显然，模块化UPS最符合这一要求。无论是交流模块化UPS还是直流模块化UPS（高压直流）都体现出了更高的可用性和易维护性。 3）然后是“省”，即节省。 省空间：目前的中小型数据中心大多建设在寸土寸金的楼宇之间，高密度一直是IT设备的普遍追求，如刀片式服务器。更高功率密度，体积更加小巧的UPS能够为用户节省更多空间，对提供出租服务的企业来说，则意味着可以部署更多的IT设备用于租赁；另一方面，如前文所述，基础设施架构融合，已成为数据中心发展的趋势之一，而更高功率密度的UPS将更方便地与服务、存储等IT设备实现一体化部署，目前各主流厂家均已推出了这种一体化产品，如华为mircoDC, APC infraStruXure等。 省电费：高昂的电费开支，也使得用户更青睐高效率的UPS，因为高效率UPS除本身损耗更低之外，还能降低制冷方面的能耗开支。有一点需要指出的是，虽然大多数厂家都宣称可提供高效UPS，但负载率的影响仍然要考虑。对大部分数据中心而言，UPS的实际负载率不会超过30%（新建数据中心甚至只有10%），而随着虚拟化技术的实现，CPU利用率上升之后，UPS的实际负载率一般也不会超过40%（以1+1系统为例）。因此只有在低负载率（20%~40%）也能做到94%以上高效的UPS才最符合数据中心的实际需求。 除此之外，目前的主流服务器因为大量采用PFC校正电路，其输入功率因数已普遍超过0.9。这就要求为其供电的UPS同样应能提供0.9甚至更高的输出功率因数，否则为了匹配这些服务器，用户将不得不采购更多的UPS。 比如，按理论计算（不考虑冗余等实际情况），10台500VA/450W（功率因数0.9）的服务器，其总功耗为5KVA/4.5KW，只需采购一台5KVA输出功率因数大于0.9（输出功率大于4.5KW）的UPS即可。而如果UPS功率因数为0.8甚至更低，则需要两台5KVA的UPS。 4）最后是“智”，即智能化。 几乎所有的UPS厂商都宣称可提供智能化的设备。但目前的智能化主要还是集中在UPS本身的技术层面，或网管方面。面对IT与CT行业层出不穷的新理念、新产品，尤其是近年来伴随移动互联网而出现的智能终端、可穿戴设备，UPS行业的“智能化”显然还不够智能。那么未来十年，将有哪些方面会出现突破？ ① 能耗精细化管理 目前服务器芯片已可以通过在空闲时关闭部分功能来实现降低能耗，而服务器风扇的转速可调也已经大量应用，这些都为L1层供配电设备与L2层IT设备的联动与统一降耗提供了便利。随着传感器的大量应用，机房内的局部环境与用电情况已经可以被轻松获取，一个包含了机房内部物理生态系统（供配电系统、温控系统、IT设备等）与机房外部自然生态系统（电网信息、气象信息、用户使用信息等）的综合能耗管理系统已经初见雏形，一些互联网巨头以此为基础通过机器学习技术将最终实现整个数据中心的自我优化与瓦特级的能耗管理。 Guidance: efficient, intelligent modular UPS is obviously more in line with the requirements of future data center development. It is understood that the current modular UPS market growth rate of more than 6%, is expected to exceed 10% in the future. In the recently concluded CMM gathering and mining, modular UPS, as an independent bidding segment, has occupied more than 14% of the purchasing share of capacity segments above 120kVA. In the telecommunications industry, high frequency and modularity have become the main trend of UPS procurement. 3 what kind of UPS do data centers need? First of all, we should admit that there are still huge differences between different industries in the cognition and application of UPS. The application of various schemes varies from person to person, and there is no uniform standard. But on the premise of ensuring reliable power supply, the author thinks that the future data center will put forward higher requirements for power supply and distribution system in the following aspects. 1) first is "fast", that is, rapid construction and rapid expansion. At present, the concept of modularization has gradually been accepted by everyone in the way of data center construction. Whether it is a modular data center or a container data center, this is a concrete realization of this concept. Modular UPS is also consistent with this concept. If we only look at the overall deployment speed, the difference between modularized UPS and tower UPS is not great. However, the advantages of modularization will be obvious if we want to expand our capacity in the later stage and invest in the initial stage. First of all, the power module based on demand expansion is more in line with the needs of business development. Especially for Internet enterprises with an average life span of only 3 to 5 years, who can complete the deployment one day earlier and realize the expansion one day earlier, can win customers one step earlier and occupy the market one step earlier. Compared with the installation time of traditional tower UPS for one to two weeks, modular UPS can only be completed in a few minutes. Second, the increasingly fierce business competition, the unpredictable market environment, and the uncertainty of future development require CEOs to find the most appropriate balance between long-term planning and initial investment. Modular structure only needs to reserve appropriate space, without one-time investment. In the future, according to business development, the investment can be divided into batches and phases, which can significantly reduce the operational risk of enterprises. For customers, whether self-built or rental, modular UPS is more suitable for the long-term development of enterprises in the future. 2) followed by "Yi", that is, ease of use and high availability. Comparing with the complex Tire4 architecture and 2N system designed by traditional data centers to ensure reliability, bypass mode, direct power supply plus UPS backup and other "incredible" solutions are being adopted by Internet giants. It is the realization of virtualization technology that makes Internet enterprises from pursuing pure power supply reliability to attaching more importance to the availability represented by rapid maintenance. Therefore, UPS is also as easy to maintain as IT devices. This UPS has two requirements: 1, failure can not affect business operation, that is, does not affect the normal power supply; 2, after failure to facilitate maintenance, the best operation and maintenance personnel can maintain themselves without contacting the manufacturer. Obviously, modular UPS is most suitable for this requirement. Both AC modular UPS and DC modular UPS (HVDC) show higher availability and maintainability. 3) and then "save", that is, saving. Save space: Most of the current small and medium-sized data centers are built between small and medium-sized buildings, high density has been the common pursuit of IT equipment, such as blade servers. Higher power density and smaller UPS can save more space for users, which means more IT equipment can be deployed for leasing for rental enterprises; on the other hand, as mentioned earlier, infrastructure convergence has become one of the trends in data center development, and higher power density. UPS will be more convenient to deploy with IT devices such as service and storage. At present, all the mainstream manufacturers have launched this integrated product, such as Huawei mircoDC, APC infra StruXure and so on. Power savings: High electricity bills also favor high-efficiency UPS, because high-efficiency UPS, in addition to its own lower wastage, can also reduce refrigeration energy costs. It should be noted that while most manufacturers claim to be able to provide efficient UPS, the impact of load rates still needs to be considered. For most data centers, the actual load rate of UPS will not exceed 30% (even 10% for new data centers), and with virtualization technology, the actual load rate of UPS will generally not exceed 40% (for example, 1 + 1 systems) as CPU utilization increases. Therefore, only when the low load rate (20% ~ 40%) can achieve more than 94% of the efficient UPS is most in line with the actual needs of the data center. In addition, the input power factor of the current mainstream servers has generally exceeded 0.9 because of the large number of PFC correction circuits. This requires that UPS powered by them should also provide 0.9 or even higher output power factor, otherwise in order to match these servers, users will have to purchase more UPS. For example, 10 500 VA / 450 W (power factor 0.9) servers with a total power consumption of 5 KVA / 4.5 KW can be purchased by purchasing only one UPS with an output power factor of 5 KVA greater than 0.9 (output power greater than 4.5 KW). If the UPS power factor is 0.8 or even lower, two 5KVA UPS will be needed. 4) finally, intelligence. Almost all UPS manufacturers claim that they can provide intelligent devices. But the current intelligence is mainly concentrated on the technical level of UPS itself or network management. In the face of IT and CT industry emerge in an endless stream of new ideas and new products, especially 华为通信电源,华为电源官网,华为高频开关电源,华为-48v开关电源,华为开关电源模块,华为网络机柜,华为服务器机柜,华为室外一体化机柜,华为OLT电源,华为直流电源,华为开关电源,华为综合柜,华为UPS,UPS5000-E,UPS2000-A,UPS2000-G,UPS8000-D,UPS5000-A,华为TP48200,华为TP48300,华为TP48600 华为-48v通信高频直流开关电源 华为通信电源,华为开关电源,华为-48v开关电源,华为高频开关电源,华为直流电源 华为UPS电源未来数据中心需求 |
