Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 2, fig. 2 is a schematic overall structure diagram of an embodiment of the present invention.
In an embodiment of the present invention, the hard disk Raid card and expansion card connection wiring structure mainly includes a main board 2, a hard disk bracket 3, a partition board 4, and a signal cable 5. Wherein, mainboard 2 and hard disk bracket 3 all set up in box 1, and both divide the inside both sides (like the left and right sides) of quick-witted case simultaneously. The main board 2 is provided with a Raid card a, and the hard disk bracket 3 is provided with an expansion card b and a plurality of hard disks. A partition 4 is also provided in the case 1 between the main board 2 and the hard disk tray 3 to partition them. The signal cable 5 is connected between the Raid card a and the expansion card b, and is used for transmitting SAS signals.
Importantly, the mainboard 2 and the hard disk bracket 3 are arranged at specific positions in the box body 1, so that the Raid card a arranged on the mainboard 2 is closer to the partition board 4 and farther from the outer side of the mainboard 2. Meanwhile, a cable through hole 401 is formed in the partition board 4, and one end of the signal cable 5 is connected with the Raid card a, passes through the cable through hole 401 and then is connected with the expansion card b.
So, signal cable 5 can directly pass behind the cable through-hole 401 on baffle 4 and link to each other with expansion card b, the hard disk Raid card that this embodiment provided connects wiring structure with expansion card, on the basis that does not change 1 inner structure of box, through the distribution mode of adjustment mainboard 2 and hard disk bracket 3 in box 1, it is nearer to make Raid card a on the mainboard 2 apart from the distance of baffle 4, rethread signal cable 5 directly passes cable through-hole 401 on baffle 4 and links to each other with expansion card b, the overall length of signal cable 5 has been reduced by a wide margin, SAS signal link loss has been reduced, the hard disk performance has been improved. Meanwhile, in the server chassis which is widely used at present, the wiring mode follows the wiring principle of 'close to the wall' so as to avoid influencing the electronic components installed in the server chassis, and therefore, in the wiring mode between the Raid card a and the expansion card b in the prior art, the signal cable 5 needs to be connected with the expansion card b after being wound and wired far around the inner wall (namely the outer side of the main board 2) of the chassis 1 from the Raid card a, and the hard disk Raid card and the expansion card connection wiring structure provided by the embodiment overcomes the technical bias about the wiring mode in the prior art after the cable through hole 401 is formed in the partition plate 4, so that the signal cable 5 can directly penetrate through the cable through hole 401 nearby to conduct wiring on the basis that the electronic components are not influenced.
Generally, based on the fact that the installed position of the Raid card a on the main board 2 is in the non-center position, the Raid card a can be made to be closer to the partition board 4 (i.e., L1 shown in the figure) and farther from the outside of the main board 2 (i.e., L2 shown in the figure and L2> L1) by adjusting the installation-side position of the Raid card a in the case 1, and based on this idea, considering that the installed position of the expansion card b on the hard disk tray 3 is also in the non-center position, the expansion card b is also made to be closer to the partition board 4 (i.e., L3 shown in the figure) and farther from the outside of the hard disk tray 3 (i.e., L4 shown in the figure and L4> L3) by adjusting the installation-side. So configured, the overall length of the signal cable 5 can be further reduced.
In addition, in order to reduce the routing length of the signal cable 5 as much as possible, in this embodiment, the distance between the Raid card a and the cable through hole 401 is equal to the distance between the Raid card a and the partition board 4. With such an arrangement, the cable through hole 401 is opened at a position on the partition board 4 corresponding to the Raid card a vertically, so that the routing length of the signal cable 5 between the Raid card a and the cable through hole 401 can be shortened to a minimum value, i.e., the distance between the Raid card a and the partition board 4.
In a preferred embodiment with respect to the wire signal cable 5, the signal cable 5 mainly comprises three parts, a first section of wire 501, a middle section of wire 503 and a last section of wire 502. The first line 501 is connected to the Raid card a, passes through the cable through hole 401, and is distributed from one side of the partition 4 to the other side. The end line 502 is connected to the expansion card b, and the middle line 503 is connected between the head line 501 and the end line 502. With this arrangement, the overall length of the signal cable 5 is the sum of the three cables, i.e., the head wire 501, the middle wire 503 and the tail wire 502.
Specifically, in order to reduce the overall length of the signal cable 5 as much as possible, after one end of the first line 501 is connected to the Raid card a, the first line 501 may extend and distribute along a direction perpendicular to the partition board 4 and pass through the cable through hole 401 along the axial direction, so that the length of the first line 501 reaches the theoretical minimum value, i.e., L1.
Similarly, after one end of the tail line 502 is connected to the expansion card b, the tail line may also extend along a direction perpendicular to the partition board 4 until it abuts against the surface of the partition board 4, so that the length of the tail line 502 reaches the theoretical minimum value, i.e., L3.
As for the middle segment wire 503, it can be closely distributed on the surface of the partition board 4 and kept in a horizontal state, and its both ends are vertically connected with the end of the first segment wire 501 and the end of the tail segment wire 502 respectively, and its length is L5.
In summary, in a preferred embodiment, the overall length of the signal cable 5 is L1+ L3+ L5, which is substantially smaller than the sum of L2+ L4+ L5 and the remaining length of the far line and the folding line in the prior art, and the presence of L3 can ensure that the hard disk tray 3 can be pulled out of the case 1 along the longitudinal direction by a certain distance, so as to facilitate the replacement and disassembly of the hard disk.
The embodiment further provides a server chassis, which mainly includes a chassis 1 and a hard disk Raid card and expansion card connection wiring structure arranged in the chassis 1, where specific contents of the hard disk Raid card and expansion card connection wiring structure are the same as those described above, and are not described herein again.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
