At present, space-saving, easy to centralize management, easy to expand and provide uninterrupted service, become the new requirements for the next generation of servers, and blade servers can meet this demand, and thus the blade server market demand is expanding, with good market prospects. There are two major categories of blade servers on the market today: one is designed mainly for the telecom industry, with interface standards and size specifications in line with PICMG (PCI Industrial Computer Manufacturer's Group) 1.x or 2.x. In the future, PICMG 3.x compliant products will be introduced, and blades and enclosures from different manufacturers using the same standards will be compatible with each other in theory. Another category of universal computing design, the interface may adopt the above standards or vendor standards, but the size specifications are vendor-defined, focusing on performance to price ratio, currently belong to this category of products are mostly. Blade servers are currently most suitable for cluster computing and IxP to provide Internet services. Differences between each other.
The main difference is the appearance. Blade servers can be inserted into multiple very thin servers that share a common total power supply, but heat dissipation has always been a bad problem to solve. Tower servers look just like our desktop computers.
Rackmount servers , are available in standard racks. Usually it is calculated by U. If you handle hosting, it is better to use rack type in order to save money.
Standard cabinets are widely used for stacking computer network equipment, communication equipment with/without wireless, electronics and other equipment. Cabinets have the advantages of enhancing electromagnetic shielding, weakening equipment working noise, and reducing the ground area occupied by equipment. For some high-grade cabinets, also has air filtration function, improve the quality of precision equipment working environment. Many engineering-grade equipment panel width are used 19 inch, so 19 inch cabinet is the most common a standard cabinet. 19 inch standard cabinet types and styles are very much, also have imported and domestic points, price and performance gap is also very obvious.
The same size of different grades of cabinet prices may vary by several times. Users to buy standard cabinets according to the specific circumstances of the installation of stacked equipment and budget to choose the right product. Standard cabinet structure is relatively simple, mainly including the basic framework, internal support system, wiring system, ventilation system. Standard cabinet according to the assembly form and material selection of different, can be divided into many performance and price grades. 19 inch standard cabinet appearance has a width, height, depth three conventional indicators.
Although for 19-inch panel equipment installation width of 465.1mm, but the physical width of the cabinet common products for 600mm and 800mm two. The height is generally from 0.7M-2.4M, according to the number of equipment in the cabinet and unified tone, usually manufacturers can customize special height, common finished 19 inch cabinet height of 1.6M and 2M. cabinet depth is generally from 400mm-800mm, according to the size of the equipment in the cabinet, usually manufacturers can also customize special depth of the product, common finished 19 inch cabinet depth of the height occupied by the equipment installed in the standard 19-inch cabinet is expressed in a special unit "U", 1U=44.45mm. 19-inch standard cabinet equipment panels are generally manufactured according to nU specifications. For some non-standard equipment, most of them can be installed into the 19-inch chassis and fixed by additional adapters.
