## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims the priority benefit of Taiwan application serial no. 99141542, filed on Nov. 30, 2010. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.
BACKGROUND
1. Field of the Invention
The invention relates to a server. Particularly, the invention relates to a server with a pluggable hard disc module.
2. Description of Related Art
A server is a core computer in a network system used for serving various computers, which can provide functions such as storage and print service for network users, and provide clients to share various resources within the network environment. A basic structure of the server is approximately the same to a general personal computer, which is composed of a central processing unit (CPU), a memory and an input/output (I/O) device, etc., and the devices are connected through a bus. A north bridge chip is used to connect the CPU and the memory, and the I/O device is connected through a south bridge chip. A chassis structure of the server has three evolution stages from earlier tower chassis to rack mount chassis stressing centrality, and then blade servers of high-density calculation.
Taking a rack mount server as an example, the rack mount server is a server with an appearance designed according to uniform standards, which is used in collaboration with a cabinet. The rack mount server can be regarded as a tower server with an optimized structure, and a design principle thereof is to reduce a space occupation of the server as far as possible. Many professional network devices apply the rack mount structure, and have a flat shape as that of a drawer, for example, switches, routers and hardware firewalls, etc. A width of the rack mount server is 19 inches, and a height thereof applies a unit of U (1U=1.75 inches=44.45 mm), and the servers are generally complied with standards of 1U, 2U, 3U, 4U, 5U or 7U.
The size of the cabinet is also complied with a common industrial standard, which is generally between 22U and 42U. The cabinet includes a detachable sliding rack according to the height thereof, and the user can flexibly adjust the height according to a height of the server, so as to store network devices such as a server, a hub, a disk array, etc. After the server is settled, the I/O lines thereof are all led out from the rear of the cabinet (all interfaces of the rack mount server are also located at the rear of the cabinet), and are uniformly disposed in a cable slot of the cabinet, and are attached with labels to facilitate management.
Generally, a hard disc module, a main board module, a power connection interface and a data transmission interface of the rack mount server are not located at a same side of a chassis, so that the user cannot pull out the hard disc module and the main board module and plug or unplug a power line and a data transmission line from the same side of the chassis, which is inconvenient in utilization.
SUMMARY OF THE INVENTION
The invention is directed to a server, in which a hard disc module, a main board module, a power connection interface and a data transmission interface are all located at a front end of a chassis.
The invention provides a server including a chassis, a middle plate, a transfer plate, a hard disc module, a main board module and a cable arranging module. The chassis has a bottom plate, two side plates, a front end and a back end. The middle plate is disposed in the chassis. The middle plate is perpendicular to the bottom plate and parallel to the side plates, and divides the chassis into a first sub-space and a second sub-space. The transfer plate is disposed in the first sub-space and is adjacent to the back end. The main board module is disposed in the first sub-space, and is suitable for being pulled out from the front end. The main board module is electrically connected to the transfer plate. The hard disc module is disposed in the second sub-space, and is suitable for being pulled out from the front end. The hard disc module includes a hard disc cage, a back plate and a plurality of hard discs. The hard disc cage is suitable for sliding into the second sub-space from the front end. The hard disc cage has a first side and a second side parallel to the side plates. The second side has a plurality of hard disc openings. The back plate is fixed to the first side of the hard disc cage and is parallel to the middle plate. The hard discs are detachablly disposed in the hard disc cage and electrically connected to the back plate. When the hard disc cage is pulled out from the chassis, the hard discs are suitable for being installed to or pulled out from the hard disc cage through the hard disc openings. The cable arranging module includes a fixing frame, a chain structure and a cable set. The fixing frame is fixed on the middle plate. The chain structure is formed by a plurality of pivoted elements pivoted in sequence. A first end of the chain structure is connected to the fixing frame, and a second end of the chain structure is connected to the hard disc cage. The fixing frame and the chain structure commonly form a chamber. The cable set is located in the chamber and electrically connected to the transfer plate and the back plate. When the hard disc module is located in the chassis, the chain structure is bended and contained in the chassis. When the hard disc module is pulled out from the chassis, the chain structure drives the cable set to be curved and move. When the hard disc module is pulled out from the chassis entirely, the chain structure is extended and at least partially located out of the chassis.
In an embodiment of the invention, the server further includes a plurality of cooling fans disposed at the back end.
In an embodiment of the invention, the server further includes a plurality of power lines connected between the cooling fans and the transfer plate.

In an embodiment of the invention, the server further includes a first slide rail, a second slide rail, a first sliding member and a second sliding member. The first slide rail and the second slide rail are disposed in the second sub-space and parallel to the two side plates. The first sliding member and the second sliding member are slidably disposed on the first slide rail and the second slide rail, respectively, where the hard disc cage is connected to the first sliding member and the second sliding member and located between the first slide rail and the second slide rail. The hard disc module is suitable for being entirely pulled out from the front end of the chassis as the first sliding member and the second sliding member are slid relative to the first slide rail and the second slide rail.
In an embodiment of the invention, the fixing frame is extended along a first axial line, and the first axial line is parallel to an extending direction of the first slide rail and located under the first slide rail.
