随着数据中心建设向着整体可用性的方向发展，机房对机柜管理的需求日益增长。用户在选购机柜时应考虑以下几方面的因素：

　　With the development of data center construction towards overall availability, the demand for cabinet management in data centers is increasing day by day. Users should consider the following factors when choosing a cabinet:

　　1、承重保证：随着机柜内所放置产品密度的加大，良好的承重能力是对一款合格机柜产品的基本要求。不符合规格的机柜，不能有效保护机柜内的设备，甚可能影响整个系统。

　　1. Load bearing guarantee: As the density of products placed inside the cabinet increases, good load-bearing capacity is a basic requirement for a qualified cabinet product. Cabinets that do not meet specifications cannot effectively protect the equipment inside the cabinet and may even affect the entire system.

　　2、温度控制系统：机柜内部有良好的温度控制系统，可避免机柜内产品的过热或过冷，确保设备的运作。机柜可选择全通风系列，可配备风扇（风扇有寿命保证），在炎热的环境下可安装独立空调系统，在严寒环境下可安装独立加热保温系统。

　　2. Temperature control system: There is a good temperature control system inside the cabinet, which can avoid overheating or overcooling of the products inside the cabinet and ensure the efficient operation of the equipment. The cabinet can be selected from the fully ventilated series and equipped with fans (with guaranteed lifespan). It can be installed with an independent air conditioning system in hot environments and an independent heating and insulation system in cold environments.

　　3、抗干扰能力：款功能齐备的机柜应提供各类门锁及其他功能，例如防尘、防水或电子屏蔽等高度抗扰性能，还应提供适合的附件及安装配件支持，让布线更为方便，同时易于管理，省时省力。

　　3. Anti interference capability: A fully functional cabinet should provide various door locks and other functions, such as high anti-interference performance such as dust, water, or electronic shielding. Suitable accessories and installation support should also be provided to make wiring more convenient and easy to manage, saving time and effort.

　　4、线缆管理：线缆出现问题怎么办？在规模巨大的机房里，在林立的机柜中穿行尚且困难，更别提快速寻找和维修出现故障的线路了。从机柜内部线缆附设的角度看，今天的数据中心机柜配置密度更高，容纳的IT设备更多，大量采用冗余配件（如冗余电源、存储阵列等），机柜内设备配置频繁变换，数据线和电缆随时增减。所以，机柜必须提供充足的线缆通道，能从机柜顶部、底部进出线缆。在机柜内部，线缆的铺设必须方便、有序，与设备的线缆接口靠近，以缩短布线距离，减少线缆的空间占用，保证散热气流不会受到线缆的阻挡，同时还要保证在故障情况下能对设备布线进行快速定位。

　　4. Cable management: What should I do if there is a problem with the cable? It is still difficult to navigate through numerous cabinets in a huge computer room, let alone quickly locate and repair faulty lines. From the perspective of cable attachment inside the cabinet, today's data center cabinets have higher configuration density, accommodate more IT equipment, and use a large number of redundant accessories (such as redundant power supplies, storage arrays, etc.). The equipment configuration inside the cabinet frequently changes, and data cables and cables can be added or removed at any time. So, the cabinet must provide sufficient cable channels to allow cables to enter and exit from the top and bottom of the cabinet. Inside the cabinet, the laying of cables must be convenient and orderly, close to the cable interfaces of the equipment, in order to shorten the wiring distance, reduce the space occupation of cables, ensure that the heat dissipation airflow is not obstructed by cables, and also ensure that the equipment wiring can be quickly located in case of faults.

　　5、配电系统：随着机柜内IT高密度安装趋势的日益显著，配电系统成为机柜能否发挥其应有效能的关键环节。合理的电源分配直接关系到整个IT系统的可用性，而这也是过去被很多机房管理人员忽视的问题。由于IT设备日益小型化，机柜内设备安装的密度不断增加，这就对机柜内配电系统提出了严峻的挑战。与此同时，输入、输出端口的增多，也对配电系统安装的可靠性提出了很高的要求。再考虑到目前大多数服务器双电源供电的需求，更使得机柜内电源分配越来越繁杂。

　　5. Power distribution system: With the increasing trend of high-density IT installation inside cabinets, the power distribution system has become a key link in whether cabinets can perform their intended functions effectively. Reasonable power allocation is directly related to the availability of the entire IT system, which has been overlooked by many data center managers in the past. Due to the increasing miniaturization of IT equipment, the density of equipment installation in cabinets is constantly increasing, which poses a serious challenge to the power distribution system inside cabinets. At the same time, the increase in input and output ports also places high demands on the reliability of power distribution system installation. Considering the current demand for dual power supply in most servers, the distribution of power within the cabinet has become increasingly complex.

　　合理的机柜电源分配系统的设计，应遵循以可靠性设计为核心，专门针对机柜系统设计，与配电系统充分协调、无缝配合的原则，同时要考虑安装的方便性，以及智能化管理、适应性强、便于操作与维护等特点。机柜的配电系统，应使电源更接近负载，以减少电源通路中的故障点。同时应逐步实现负载电流的本地及远程监控，以及电源分配的远程控制，使电源分配管理纳入机房整体的智能化管理体系中。

　　The design of a reasonable cabinet power distribution system should follow the principle of reliability design as the core, specifically designed for the cabinet system, and fully coordinated and seamlessly coordinated with the power distribution system. At the same time, it should consider the convenience of installation, as well as the characteristics of intelligent management, strong adaptability, and easy operation and maintenance. The power distribution system of the cabinet should make the power supply closer to the load to reduce the number of fault points in the power path. At the same time, local and remote monitoring of load current, as well as remote control of power distribution, should be gradually implemented to integrate power distribution management into the overall intelligent management system of the computer room.
