隨著數據中心建設向著整體可用性的方向發展，機房對機柜管理的需求日益增長。用戶在選購機柜時應考慮以下幾方面的因素：

　　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、承重保證：隨著機柜內所放置產品密度的加大，良好的承重能力是對一款合格機柜產品的基本要求。不符合規格的機柜，不能有效保護機柜內的設備，甚可能影響整個系統。

　　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、溫度控制系統：機柜內部有良好的溫度控制系統，可避免機柜內產品的過熱或過冷，確保設備的運作。機柜可選擇全通風系列，可配備風扇（風扇有壽命保證），在炎熱的環境下可安裝獨立空調系統，在嚴寒環境下可安裝獨立加熱保溫系統。

　　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、抗干擾能力：款功能齊備的機柜應提供各類門鎖及其他功能，例如防塵、防水或電子屏蔽等高度抗擾性能，還應提供適合的附件及安裝配件支持，讓布線更為方便，同時易于管理，省時省力。

　　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、線纜管理：線纜出現問題怎么辦？在規模巨大的機房里，在林立的機柜中穿行尚且困難，更別提快速尋找和維修出現故障的線路了。從機柜內部線纜附設的角度看，今天的數據中心機柜配置密度更高，容納的IT設備更多，大量采用冗余配件（如冗余電源、存儲陣列等），機柜內設備配置頻繁變換，數據線和電纜隨時增減。所以，機柜必須提供充足的線纜通道，能從機柜頂部、底部進出線纜。在機柜內部，線纜的鋪設必須方便、有序，與設備的線纜接口靠近，以縮短布線距離，減少線纜的空間占用，保證散熱氣流不會受到線纜的阻擋，同時還要保證在故障情況下能對設備布線進行快速定位。

　　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、配電系統：隨著機柜內IT高密度安裝趨勢的日益顯著，配電系統成為機柜能否發揮其應有效能的關鍵環節。合理的電源分配直接關系到整個IT系統的可用性，而這也是過去被很多機房管理人員忽視的問題。由于IT設備日益小型化，機柜內設備安裝的密度不斷增加，這就對機柜內配電系統提出了嚴峻的挑戰。與此同時，輸入、輸出端口的增多，也對配電系統安裝的可靠性提出了很高的要求。再考慮到目前大多數服務器雙電源供電的需求，更使得機柜內電源分配越來越繁雜。

　　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.

　　合理的機柜電源分配系統的設計，應遵循以可靠性設計為核心，專門針對機柜系統設計，與配電系統充分協調、無縫配合的原則，同時要考慮安裝的方便性，以及智能化管理、適應性強、便于操作與維護等特點。機柜的配電系統，應使電源更接近負載，以減少電源通路中的故障點。同時應逐步實現負載電流的本地及遠程監控，以及電源分配的遠程控制，使電源分配管理納入機房整體的智能化管理體系中。

　　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.
