Servomechanism
Technical field
The present invention relates to a kind of servomechanism, and be particularly related to a kind of servomechanism with removable hard drive module.
Background technology
Servomechanism is the core computer of serving each computer in network system, and the functions such as disk that network user needs and print service can be provided, and also can supply each user side every resource in share web environment each other simultaneously.The basic framework of servomechanism and general PC are roughly the same, by parts such as central processing unit (CPU), storer (Memory) and I/O (I/O) equipment, formed, and connected in inside by bus (Bus), by north bridge chips, connect central processing unit and storer, and connect input-output apparatus etc. by South Bridge chip.Servomechanism has approximately experienced three evolution process by casing structure: from early stage tower case to emphasizing to concentrate the rack of performance, again to the blade servomechanism of high density account form.
At this, take rack server as example, rack server is the servomechanism that a kind of outward appearance designs according to unified standard, coordinates the unified use of rack.Can say that rack is a kind of tower servomechanism of optimizing structure, its design aim is mainly in order to reduce as far as possible taking of servomechanism space.A lot of specialized network equipment is all the structure that adopts rack, and it mostly is flat, just as drawer.For example switch, router, hardware fire wall these.The width of rack server is 19 inches, and height be take U as unit (1U=1.75 inch=44.45 millimeter), conventionally has 1U, 2U, 3U, 4U, 5U, the servomechanism of several standards of 7U.
The size of rack is also to adopt general industrial standard, conventionally from 22U to 42U not etc.In rack, by the height of U, have dismountable slip bracket, user can be according to the absolute altitude flexible height of own servomechanism, to deposit the network equipments such as servomechanism, hub, magnetic sheet disk array cabinet.After servomechanism is well placed, its all I/O lines are all drawn (all interfaces of rack server also in the wings) from the rear of rack, and unified being placed in the wire casing of rack, generally posts label, is convenient to management.
To have the servomechanism of removable hard drive module, when hard disk module is when cabinet moves, the cable that is connected in hard disk module can move or deflection thereupon.If cable, by suitably fixing and irregular mobile deflection, may not make cable come off from hard disk module.Therefore how to take into account deflection degree of freedom the mobile deflection of cable, may make cable come off from hard disk module.Therefore how taking into account the deflection degree of freedom of cable and avoid it to come off in hard disk module is important subject under discussion.
