1. Reliable quality assurance
Choosing the right server and cabling cabinet is important, and the slightest negligence can lead to huge losses. No matter which brand of product it is, quality is the first thing that users should consider.
2. Load-bearing guarantee
With the increase of the density of products placed in the cabinet, good load-bearing capacity is the basic requirement for a qualified cabinet product. Cabinets that do not meet the specifications may not be able to properly protect the equipment in the cabinet due to the poor quality of the cabinet, and the result may affect the entire system.
3. Temperature control system
There is a good temperature control system inside the cabinet, which can avoid overheating or overcooling of the products in the cabinet to ensure the efficient operation of the equipment. The cabinet can be fully ventilated, equipped with a fan (the fan has a life guarantee), an independent air conditioning system can be installed in a hot environment, and an independent heating and insulation system can be installed in a cold environment.
4. Anti-interference and others
A fully functional cabinet should provide a variety of latches and other features, such as a high degree of immunity to dust, water, or electronic shielding; At the same time, suitable accessories and installation accessories should be provided to make wiring more convenient, easy to manage, and save time and effort.
5. After-sales service
The effective services provided by the enterprise and the comprehensive equipment protection program provided by the enterprise can bring great convenience to the installation and maintenance of users.
6. Power distribution system
How can cabinets cope with the increase in power density? With the increasing trend of high-density IT installation in the cabinet, the power distribution system has become a key link in whether the cabinet can play its due effective performance. Reasonable power distribution is directly related to the availability of the entire IT system, and is an important basic link for the entire system to play its due effective performance, which is also a problem that has been ignored by many computer room managers in the past. Due to the increasing miniaturization of IT equipment, the density of equipment installed in the cabinet is increasing, for example, a 7U blade server will require about 3 kVA of power distribution, while a 42U high cabinet may install up to 8 such servers, and the total power distribution demand will reach 24 kVA. This poses a serious challenge to the power distribution system in the cabinet. At the same time, the increase of input and output ports also puts forward high requirements for the reliability of power distribution system installation.
The reasonable design of the cabinet power distribution system should follow the principle of taking reliability design as the core, designing the cabinet system, fully coordinating and seamlessly cooperating with the power distribution system, and considering 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 bring the power supply closer to the load to reduce the point of failure in the power path. At the same time, the local and remote monitoring of load current, as well as the remote control of power distribution, should be gradually realized, so that the power distribution management should be incorporated into the overall intelligent management system of the computer room.
7. Cable layout
What should I do if there is a problem with the cable? In a huge machine room, it can be difficult to navigate through the many cabinets, let alone quickly find and repair faulty lines. Whether the overall solution of the cabinet is in place and the management of the cabinet for cables will become one of the key aspects of the investigation.
