The cabinet has always been regarded as a low-value, ancillary product in IT applications. It is just a container for accommodating servers and other equipment. However, low-cost cabinets are the most direct physical protection for expensive IT equipment. Pay attention to the IT equipment itself, but ignore the IT microenvironment in which it is located, and more data centers are drawn to the edge of danger.
What is a cabinet? Many people think of a cabinet as a cabinet for IT equipment. Cabinets are cabinets, but they are not the only ones. With the development of computer and network technologies, IT facilities such as servers and network communication equipment in data centers are developing in the direction of miniaturization, networking, and racking. This has brought new changes to the construction model of the data center. The cabinet is gradually becoming one of the protagonists in this change. For data centers, cabinets are becoming an important part of it.
The rack server from Intel has made the trend of IT equipment racking, which brings an increasingly prosperous market to the cabinet. The racking of IT equipment has changed the specifications of the cabinet. The most obvious manifestation is the reduction in the size of a single server. The height space occupied by the server is decreasing day by day, and the depth space is getting larger and larger, so the depth requirements of the cabinet are gradually increasing. In addition, the maximum installation density of IT equipment has become the current development trend of rack servers. The extensive use of Iu blades makes it possible to install up to 42 servers in a 42U cabinet, and each server uses two CPUs (or even more), and the hard disks are also in the form of internal arrays, which will release more during operation. Heat, resulting in a very high heat density in the cabinet. Ignoring the cooling problems of equipment inside the cabinet may also cause IT equipment failures and reduced life.
At the same time, the compatibility of the cabinet is also a headache for users. Nowadays, equipment from different manufacturers will be installed in the data center cabinets, so the cabinets must have good compatibility (such as Oriental Songbai cabinets). If the compatibility of the cabinet is not good, when upgrading IT equipment, the original cabinet may not meet the demand, and the user is forced to replace the entire equipment room equipment. This unnecessary cost is common in the early construction of the equipment room. Insufficient compatibility will inevitably lead to poor scalability of the overall cabinet solution and cannot meet the ever-changing demands of the IT industry. For users, it obviously reduces the life cycle of the system and generates excessive costs.
With the development of the data center toward the direction of overall availability, the demand for cabinet management in the computer room is increasing. It is foreseeable that a cabinet solution that fully meets the needs of the data center and has future scalability will be able to better solve the user's problems and improve the management level of the user's IT system. Several factors:
Reliable quality assurance, it is very important to choose a suitable server cabinet and wiring cabinet, and slight negligence may result in huge losses. Regardless of which brand of product, quality is the first link users must consider.
Load-bearing guarantee, as the density of products placed in the cabinet increases, good load-bearing capacity is the basic requirement for a qualified cabinet product. A cabinet that does not meet the specifications may not be able to effectively protect the equipment in the cabinet due to the poor quality of the cabinet. As a result, the entire system may be affected.
Temperature control system. There is a good temperature control system inside the cabinet to avoid overheating or overcooling of the products in the cabinet to ensure the efficient operation of the equipment. The cabinet can choose the full ventilation series, and can be equipped with fans (fans have 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.
Anti-interference and other, a fully functional cabinet should provide various door locks and other functions, such as dustproof, waterproof or electronic shielding and other high anti-interference performance; at the same time should provide suitable accessories and installation accessories support to make wiring Convenient, easy to manage at the same time, saving time and effort.
After-sales service, the effective services provided by the enterprise, and the comprehensive equipment protection program provided can bring great convenience to the user's installation and maintenance.
In addition to the above points, the cabinet solution in the data center should also consider the design of cable layout and power distribution to ensure the good operation of the system and the convenience of upgrading.
