What is machine ark?
As the development of the computer and network technology, the IT equipment such as equipment of communication of server, network is siding with the way that miniaturization, network, frame changes to develop, this built means to bring new change to the compose of data center, and machine ark, become one of protagonist in change. To several according to the center character, machine ark is becoming his main component, even someone says, machine ark is data center!
According to IDC data statistic, 300 thousand servers of Chinese market consign are medium 2003, having 25% about is frame type server; The data that comes from Intel company shows, to 2005, global server will have 66% to be frame type server. Compare with the narrows gradually trend photograph of market of tower type server, frame type server, bit type server (also need installation to be in machine ark) the period that lying to develop quickly however. The tide that IT equipment frame turns, brought the market that flourishs increasingly for machine ark.
And long-term since, machine ark is regarded the low cost that the server holds in IT application, accessary product, do not take seriously for the person. But, the machine ark of low value is the physical protection with costly IT the directest equipment however, take IT equipment itself seriously to ignore the practice of its located IT small environment however, making center of a lot of data to critical margin.
This kind lopsided how should be broken? Devote oneself to infrastructure of network key physics for a long time (NCPI) the APC company of research, survey undertook to mass data center inside global limits, it is data center to the demand end of machine ark 4 respects, namely power source of cabinet of management of quantity of heat, wire cable management, machine allocates, compatibility etc is advanced function. The ark of NetShelter set machine that APC company rolls out, systematization ground solved machine ark to apply medium high density to come loose the difficult problem of equipment of type of frame of distribution of have as an attached institution of cable of hot, much wire and management, high capacity and comprehensive and compatible different manufacturer, make data center can move below tall practicable environment thereby.

Management of quantity of heat: The frame type equipment that lets you no longer " attack of fever "
The author once saw with one's own eyes witnesses " of such grand occasion of a " , inside the computer room of some company, the door of machine ark is being opened wide, day and night of a fanner keeps be being blown, drop in temperature to very hot server is sent inside machine ark. The IT equipment measure that installs inside ark of single nowadays aircraft is increasing, power density is bigger and bigger. The server box interior of 7U of a 6 ～ placed in a certain position even 8 ～ server of type of 10 razor blade, the capacity can achieve 3 kilowatt, the machine of a 42U can install such 8 servers in ark, the quantity of heat that the equipment inside single aircraft ark produces achieves nearly 24 kilowatt! The value that machine ark quantity of heat manages cans be imagined.
