Interpretation of key parameters choose a server cabinet you should not ignore the details

When the enterprise buys a rack server, blade server, or enterprise-class network equipment, an important infrastructure to consider in addition to the device itself is the cabinet. The cabinet is the carrier that provides the operating environment for these equipments, so the status cannot be neglected. However, some users in the purchase of cabinets usually only consider the price, and did not pay attention to the cabinet parameters and cabinets are suitable for themselves, in fact, the cabinet itself has some important parameters to consider.

Two-height cabinet comparisons

Cabinet height: For cabinets, although there is a long width of such conventional size, but because the server and other facilities using a uniform size standards, so users do not need to pay special attention to specific numbers. In addition to the customized products, the cabinet is a constant width of 19 inches, the user only need to select the appropriate height according to the number of equipment cabinet. The height of the cabinet corresponds to the height of the server, common servers have 1U to 4U specifications, each U's height is about 44.5cm, and the common cabinet has 24U and 42U two kinds, the former height is about 1 meters, usually used to decorate network equipment, the latter height is about 2 meters, widely used. Users simply need to choose the corresponding size according to the total number of "U" in the device.

Different thickness of plate in different position

Sheet Thickness: Plate thickness is a more conceptual indicator, because not all users will go to quantity. The thicker the plate of the cabinet bearing capacity and stability will be stronger, but on the one hand, the weight will be greater, and the price is higher. It is necessary to pay attention to the different location of the cabinet used material thickness is not the same, there are usually 1.0, 1.2, 1.5, 2.0mm and other sizes, manufacturers if the label thickness of the plate will be individually annotated, such as the thickness of the skeleton, the thickness of the installation of the beam is how much. However, as a common user, the relationship between sheet thickness and cabinet quality is not easy to understand, so it is not a particularly important parameter.

Material and surface treatment: material refers to the materials used in various parts of the cabinet. At present, the cabinet is widely used in the production of cold-rolled steel plate, there is little room for choice. In order to protect the steel plate will not corrode, rust or wear and other damage phenomena, the surface will be properly treated. This is very similar to our common PC chassis, in addition to conventional paint, there are usually galvanized, phosphating and other special measures to insulate the steel plate and air.

Deadweight and load-bearing: These two values are very common in cabinet parameters, but for cabinets the nominal load-bearing value is much larger than the actual number of servers that can be hosted. For example, some 42U cabinets nominal load-bearing capacity of 1000Kg, and in fact, an IBM X3650 M4 such a 2U server upgrade to the top case weight is not enough 30Kg, visible cabinets have been reserved enough redundancy. But in some special environment, such as some room floor load-bearing has a special index, at this time to the cabinet plus the total weight of the server is a certain requirement.

Opening rate

Opening rate: This is a very test of the strength of the manufacturers parameters. Rack-like servers, blade servers and enterprise-class network equipment, equipment, small internal space, heat dissipation in many cases depends on the ventilation rate. However, because the cabinet is also relatively closed structure, so the opening rate directly affects the heat dissipation efficiency. In the case of guaranteeing the stability of the cabinet, the higher the opening rate, the better the heat dissipation efficiency will be, but the higher the http://www.aliyun.com/zixun/aggregation/7197.html "> Design ability of the Cabinet", It can be said that this is a manufacturer to show off the technical strength of the parameters.
