无论是一个小型数据中心还是一个超大型数据中心，无论云服务提供商或者是需要建设数据中心的新企业，数据中心设计方案的影响是非常重要的。好的设计对数据中心的建设和运维都起着非常重要的作用。
Whether small or hyperscale, a cloud service provider or a business looking to keepdata on-prem, good design is important to creating and maintaining a highlyefficient data center.
数据中心的投资是非常昂贵的，任何一个投资者都会考虑最大化投入的资源，尤其是业务需要基础设施能够时刻在线随时接入的时候。数据中心设计方案在节约成本，提高扩展能力，减少环境影响方面的影响也非常大。
Investment in infrastructure is expensive, so it makessense that any organization should always look to generate maximum output fromits resources, particularly as business needs dictate an ‘always on’ approachto data accessibility. Data design strategy can have an enormous impact, whichin turn can lead to cost savings, greater ability to scale and reducedenvironmental impact.
基于设计方案的重要性，任何建设，运行，维护一个高效数据中心的客户都需要考虑以下六个关键要素。
Withthis in mind, below are six key considerations for all businesses looking tobuild, run and sustain an efficient data center:
数据中心的大部分宕机和成本支出都与数据中心配电和制冷方案有关，如果制冷方案不好，制冷所需的耗电量可能等于甚至超过IT设备的运行耗电量。
Alarge proportion of data center outages and out-of-control costs can bedirectly tied to the power and cooling that a data center uses. If cooling isimplemented poorly, the power required to cool a data center can match or exceedthe power used to run the IT equipment itself.
为了解决这个问题，需要充分考虑气流组织，封闭通道，对配电和制冷进行模块化的管理，还能够随需求扩展。方案还需要考虑机房实时监控和趋势分析，确保方案投入最低，并能够及时发现潜在问题。
Inorder to address this issue an organization should control airflow and coolingvia containment and active airflow management that provides modular power andcooling which scales with demand/expansion. Then they should implementreal-time and trend reporting to ensure they are keeping costs low and headingoff any potential issues before they become problems.
数据中心可以看做一个完整的生命周期系统，包含部署，更新和淘汰，确保生态的健康。最佳设计实践的一个关键因素就是要保证生态周期流程的固化和量化，确保资源一致，更新及时，并且所有操作透明，可追溯并且经得起审核。
Adata center can be thought of as a living ecosystem that requires assets bedeployed, updated and brought to end of life to keep the environment healthy.One of the key design best practices is to make sure you use workflow andrepeatable business processes so you can ensure that your resources are beingmaintained consistently and in a timely fashion - and all actions aretransparent, traceable and auditable.
一个好的数据中心应该是尽量多工人操作自动化，一个或者多个数据中心采用一致的架构，有助于降低成本和员工花费在设备维护上面的时间。自动化可以分多个阶段执行，持续改良和校正，到流程化，再到跨系统集成。
Agood data center design should plan to automate as many of the operational functionsthat employees perform as possible. This helps ensure infrastructure isdeployed consistently in a single data center or across multiple data centers,while also helping to reduce costs and the time employees spend maintaining it.Automation should occur at multiple stages, from on-going discovery and audit,to workflow, and cross system integration.
从企业开始一个数据中心设计的那一刻起，设计方案和需求都在时刻调整和优化，为了满足需求变更，确保方案布局，配电，冷源和网络系统始终可用，就需要重视过程中数据的收集，分析和所呈现的结果，使团队了解当下和未来的发展情况。这样就能有效的避免当需要资源时出现资源不够的情况。
Fromthe moment a business designs its data center it is constantly beingredesigned. To keep up with these changes and ensure that space, power, coolingand networking is always available you need to have robust analytics andreporting to keep staff and management abreast of current and future capacityneeds. In this way, the business avoids running out of resources when someonein the business needs them most.
数据中心的资源会被公司各个业务部门使用，因此，在数据中心设计和规划时，一定要针对性做出计划，考虑集成相类似的解决方案，例如：建筑管理系统（BMS），IT管理系统（ITSM）以及虚拟化管理解决方案（VMware和Nutanix），这样，某个团队的数据中心可以与其他团队同步，从而使数据中心运维员工更高效的工作，而公司也能作为一个整体快速准确的工作。
The information within the data center can be leveragedby many other groups and systems within an organization. Thus, in designingyour data center and systems you should always keep in mind and planaccordingly in order to integrate solutions that can be integrated withtechnology in other areas of business. For example, building management systems(BMS), IT systems management (ITSM), and with virtualization managementsolutions like VMware and Nutanix. In this way, your data center systems cansynchronize information with other groups so that data center staff can performtheir jobs most efficiently - and the business as a whole works with speed andprecision.
如果综合考虑以上所有方面，明显的，表格和其他手工方式无法跟上现代数据中心的发展，如果要精确的进行容量管理，集中优化管理所有资源并且保持方案统一，建议部署一个全面现代化的数据中心基础架构管理解决方案（DCIM）。
Taking all the above into consideration, it becomes clearthat spreadsheets and other manual approaches cannot keep up with the changesoccurring in a modern data center. In order to perform accurate capacityplanning and keep precise centralized records for optimizing and maintain itsdesign, an organization should deploy a comprehensive and modern data centerinfrastructure management (DCIM) solution that can help to address all of theabove.
DCIM不仅仅要满足数据中心可视化，具有数据收集，分析和呈现的功能。而且要作为数据中心调整优化的决策数据来源，DCIM在普通数据中心和混合计算数据中心将变得不可或缺，在技术发展飞快并且越来越复杂的未来，这个趋势将更加明显。
This system not only provides data centervisualization, robust reporting and analytics, but also becomes the centralsource-of-truth for changes being made in the data center. DCIM solutions havebecome ubiquitous in the data center and hybrid compute infrastructure, anddeemed necessary with the complex rapidly changing technology footprint.
在当下的商业环境中，数据中心断电和设备宕机都是不可以接受的，因为数据中心的发展承载着全连接业务和数字化转型的不断发展。那些业务的存在，才是云服务提供商和企业能从高效数据中心基础设施中获得的收益。
In today’s business climate, power outages as well asdata downtime is not an option, particularly as data centers evolve in linewith the proliferation of connected devices and wider digital transformation.In keeping the above in mind, cloud service providers and independentbusinesses alike can enjoy the benefits of a highly efficient data at theadvantage of all.
