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 each computer of service in the network system, and functions such as disk that network user needs and print service can be provided, and also can supply each user side interior each item resource of share web environment each other simultaneously.The basic framework of servomechanism and general PC are roughly the same; Form by parts such as central processing unit (CPU), storer (Memory) and I/O (I/O) equipment; And connect in inside by bus (Bus); Connect central processing unit and storer through north bridge chips, and connect input-output apparatus etc. through South Bridge chip.Servomechanism has approximately experienced three evolution process by casing structure: from early stage tower case to rack that stress to concentrate performance, again to the blade servomechanism of high density account form.
Is example at this with the frame servomechanism, and the frame servomechanism is the servomechanism of a kind of outward appearance according to the unified standard design, cooperates the unified use of rack.We can say that rack is a kind of tower servomechanism of optimizing structure, its design aim mainly is in order to reduce taking of servomechanism space as far as possible.A lot of specialized network equipment all are the structures that adopts rack, and mostly it is flat, just general as drawer.For example switch, router, hardware fire wall these.The width of frame servomechanism is 19 inches, and height is unit (1U=1.75 inch=44.45 millimeter) with U, 1U is arranged usually, 2U, 3U, 4U, 5U, the servomechanism of several kinds of standards of 7U.
The size of rack also is to adopt the general-purpose industrial standard, from 22U to 42U, does not wait usually.Height by U in the rack has dismountable slip bracket, and the 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 was put, its all I/O lines were all drawn (all interfaces of frame servomechanism also in the wings) from the rear of rack, and unified being placed in the wire casing of rack generally posted label, is convenient to management.
Having the servomechanism of removable hard drive module, when the hard disk module when cabinet moves, the cable that is connected in the hard disk module can move or deflection thereupon.If cable not by suitably fixing and irregular mobile deflection, possibly make cable come off from the hard disk module.Therefore how to take into account the deflection degree of freedom of cable and move deflection, cable is come off from the hard disk module.Therefore how taking into account the deflection degree of freedom of cable and avoid it to come off in the hard disk module is important subject under discussion.
Summary of the invention
