Popular science stickers: an text to teach you to understand the rack -type server
At present, the Internet has developed rapidly, and enterprises have also taken advantage of the transformation of information. The role of servers set by IT infrastructure in enterprises is becoming increasingly important. In the process of procurement server, in addition to the key parameters such as cost, power consumption, and heat dissipation, companies often hesitate between racks, tower -type and blade servers. In this article, I will interpret the rack -type server in detail for you.
What is the rack server
The so -called rack server refers to the shape of this server. According to the shape, the server can be divided into tower, rack type, blade, and cabinet -type server. In 1994, the first rack server was born in the world.
In terms of appearance, the rack server does not seem to be like a computer, but the switch, which adopts industrial standardized production model, has a unified standard in appearance, and can be used in conjunction with the cabinet. Generally, enterprises will choose rack -type servers that meet the 19 -inch industrial standards for easy installation and deployment. The height of the rack server is U -unit (1U = 1.75 inches = 44.45 mm), usually with 1U, 2U, 3U, 4U, 5U, and 7U standards.
Rangers -type server advantage
Because the rack -type server adopts unified production and appearance standards, it can be uniformly placed and managed uniformly like more IT devices (such as switches). In addition, the rack -type server has made a variety of structural optimization internally. The purpose is to minimize the space occupation as much as possible, and the direct benefit to reduce the occupation is that the price will be much cheaper when the computer room hosted, reducing the operating cost of the enterprise. In addition, the rack server will be better than the blade server.
Rangers -type server application scenario
As the X86 server becomes the mainstream, the rack -type server is becoming more and more popular. From the scope of application, rack servers can be widely used in the Internet industry, but there are also disadvantages. Due to the optimization of internal space, scalability will be limited.
In summary, for enterprises, especially small and medium -sized enterprises, for cost considerations, want to save room space at the same time, and facilitate deployment, rack -type servers can be considered first.
For small and medium -sized enterprises, I chose an entry -level rack server -Dell PowerEdge R230. The R230 uses the Intel Dorge E3-1200 V6 quad-core processor, standard 8GB of memory and 1TB hard disk, and supports up to 4 3.5-inch wired hard disks or hot plug-in hard disks. In addition, through the Dell OpenManage management system, it helps enterprises monitor the system in real time and improve office efficiency.
