The history that installs the computer in machine ark wants the century on restrospect to 70 time end, because the equipment each other between many suppliers is incompatible at that time, installation process is very difficult. 1984, carry out with what international Electrotechnical Committee is international standard of the representing, farther establish the standard that machine ark installs telegraphic equipment and IT equipment. However, spend the emerge in large numbers of IT equipment as the high density such as bit type server, and of IT and telegraphic industry confluence deepen ceaselessly, new issue arises subsequently again. We will take your understanding to spend service system environment to fall in high density of current data center below, installation telecommunication and the machine ark difficult problem that IT equipment faces and settle way.
Cost difficult problem
Below feasibility condition, the machine ark that server manufacturer sells is very few the equipment with the competitor is compatible. Such “ has ” machine cabinet only not only cost is very high, incorporate and compositive very difficult also. To IT technology manager, they normally apt uses American APC firm supplier of such indifferent machine ark, deploy unified machine ark for data center. What this can maintain the outward appearance not only is uniform, more important still depend on can assuring the general compatibility with all IT equipment. In addition, when unified machine ark still can offer a province beforehand the project changes a solution, simplify to major early days plans and install the job. Look from cost, the economic scale that place of unified machine ark brings can let “ only ” machine ark faces enormous cost challenge undoubtedly.
Usability difficult problem
On usability problem, deserving to send air current to IT equipment is the thing that needs to be paid close attention to above all. In going a few years, IT equipment bulk is ceaseless and contractible, density of quantity of heat increases quickly however, because this creates the appearance with insufficient air current very easily, shorten then the life of IT equipment. A method that ensures machine ark cools appropriately is to deploy fanner cupboard door or stiletto door, offer enough “ natural ” to connect wind air current to IT equipment. In addition, use the machine ark switchboard of the circuit breaker with fluky function, may cause load to cut off the power and bring stop the breakdown such as machine.
Accordingly, need puts breaker in go up with a face plate, increase redundant power supply for machine ark. After machine ark is using power supply of double power source, can raise usability greatly.
But maintainability difficult problem
Major but maintainability difficult problem transplants with the server and the technology is concerned newlier. As a result of the limitation of working space, the time that installs IT equipment expenditure is quite long, still can increase at the same time stop the possibility of machine. Machine ark should the working space with enough put apart, have the characteristic such as beardless tool operation at the same time. Additional, power supply cord and data line are met sometimes block up air current, the IT equipment with the inadequate refrigeration inside attaint machine ark. Because “ wiring is wrong
