Generally choose PC chassis, appearance is first selection factors, however, choose server box, practicability is up to more important position, and generally should be mainly from the following several aspects to examine the:
Cooling sex
4 U or server use CPU tower at least for two or more, and add internal use more SCSI disk array of form, thus makes the server internal heat is very big, so good cooling sex is a excellent server the necessary conditions of the case. Radiating performance is reflected in three aspects: one is the number of fans and position, and the second is the rationality of the cooling channels, three is the case materials selection. Generally speaking, the brand server case such as can be very good ultra do this, with heavy-caliber fan directly to the CPU, memory and disk for cooling, formed from the air suction to rear exhaust (tower for the next in top out, move after a) good cooling channels, form good thermal circulation system, in time away in the case of quantity of heat, guarantee the stable operation of the server. The heat conduction and strong ability of high quality aluminum alloy or steel materials to make case shell, also can improve the thermal environment.
redundancy
4 U or tower server in the general backbone network, a perennial 24 hours of operation is inevitable, so its redundancy design also is worth to pay close attention to very much. A cooling system is the redundancy, such server box general must be equipped with special redundancy fan, when individual fan because fault when stalled, redundancy fan will immediately take work; 2 it is the power of redundancy, when the main power supply for fault failure or voltage instability, redundant power to take to work the system power supply; Three is storage media redundancy requirements case more hot swap a hard drive and is on the server of the thermal maintenance.
Excellent design, easy maintenance
Well-designed server box will provide convenient LED display lights for defenders know in time machine, lead USB port and small design will also great convenience to the user. At the same time, more case provides the design of the front of redundant power supplies, make the power maintenance is more convenient.
Materials foot
Material is always measure with small factory products giant, the most intuitive ways. With superfine case as an example, the same is 4 U or tower case, utrasmall product from the weight can reach even three or four times the hybrid product. In the cabinet with various equipment among cable, case directly to the host shielding materials involving other equipment of electromagnetic interference ability. Because the server of the case directly involves the stability of system, so some famous server motherboard will produce professional giant server case, in order to ensure that the final server the stability of the products.
In short, grasp the above the principle of choose and buy some, plus plenty to quality assurance, a good case power will become your performance powerful server system the most safe house.
