Abstract
The utility model provides a 3-to-4 SAS hard disk backplane, which comprises a PCB board, front insert slots, a back insert slot and a status indicator lamp, wherein the front surface of the PCB board is provided with four front insert slots side by side, the back surface of the PCB board is provided with the back insert slot and the status indicator lamp. The 3-to-4 SAS hard disk backplane can effectively reduce the gap between a bracket and a casing body, and effectively reduce the vibration between the bracket and the casing body by fastening screws at the four angle ends and the middle portion of the PCB board, thereby preventing damaging hard disks. Besides, by means of the status indicator lamp mounted on the back face of the PCB board, users can understand the working status of the hard disk thereby the 3-to-4 SAS hard disk backplane can expand wiring spaces, improve performance and stability of the overall storage subsystem and help to radiate heat.
Description
1, technical field
The utility model relates to a kind of hard disk backboard, and specifically a kind of 3 change the 4SAS hard disk backboard.
2, background technology
Increase along with the user environment data volume is huge, the hard disk quantity of separate unit server configures and capacity have all had and have increased by a wide margin, and the design of hard disk backboard and quality control have become a significant concern point that influences complete machine performance and stability.
Existing hard disk backboard, adopt an independent pcb board to be used for carrying out the state indication, actual components and parts have only taken the very little space of this pcb board, most of places are vacant, not only caused the huge waste on cost and the space, nor be beneficial to heat radiation, the more important thing is that it has taken the space of backboard PCB, thereby reduced the space of backboard wiring, artificial increase labile factor; And existing hard disk backboard is fixing neither be very desirable, usually hard disk is when running well, if the unfavorable words of surface of contact damping effect of hard disk bracket and housing, the vibration of this hard disk will be delivered on other hard disks, influence the operate as normal of other hard disk, cause performance loss easily.
3, summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of 3 to change the 4SAS hard disk backboard.
The technical solution of the utility model realizes that in the following manner its structure is made of pcb board, preceding slot, back slot and status indicator lamp, and the front of pcb board has been arranged side by side 4 preceding slots; The reverse side of pcb board is provided with back slot and status indicator lamp.
Four jiaos of ends of above-mentioned pcb board and middle part, two ends are provided with screw.
The utility model has the advantages that:
(1), of the present utility model 3 change the 4SAS hard disk backboards and effectively reduce space between support and the housing, reinforce by the screw at four jiaos of ends of pcb board and middle part simultaneously, effectively reduce the vibrations between hard disk bracket and the housing, prevent hard disk corruptions.
(2), this device has reasonable in design, simple in structure, easy to process, low cost and other advantages is provided with status indicator lamp especially on hard disk backboard, can understand its duty by pilot lamp, like this on the basis of completion status deixis, both increase wiring space, strengthened the performance and the stability of whole storage subsystem, helped heat radiation simultaneously again.
4, description of drawings
Accompanying drawing 1 is the Facad structure synoptic diagram of 3 commentaries on classics 4SAS hard disk backboards;
Accompanying drawing 2 is the reverse side structural representation of 3 commentaries on classics 4SAS hard disk backboards;
Mark in the accompanying drawing is represented respectively; 1, pcb board; 2, preceding slot; 3, back slot; 4, status indicator lamp; 5, screw.
5, embodiment
Change the 4SAS hard disk backboard below in conjunction with accompanying drawing 1-2 to of the present utility model 3 and do following detailed description the in detail.
Shown in accompanying drawing 1-2, of the present utility model 3 change its structure of 4SAS hard disk backboard is made of pcb board 1, preceding slot 2, back slot 3 and status indicator lamp 4, and the front of pcb board 1 has been arranged side by side 4 preceding slots 2; The reverse side of pcb board 1 is provided with back slot 3 and status indicator lamp 4.
Four jiaos of ends of pcb board 1 and middle part, two ends are provided with screw 5.
Of the present utility model 3 change the 4SAS hard disk backboards adopts 4 layers of pcb boards design, independently bus plane and stratum, and signals layer kept apart, both strengthened antijamming capability, guaranteed the integrality of signal again.
3 its processing and fabricatings of commentaries on classics 4SAS hard disk backboard of the present utility model are very simple and convenient, can process shown in the accompanying drawing to specifications.
Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
Claims (2)
1,3 change the 4SAS hard disk backboard, it is characterized in that being made of pcb board, preceding slot, back slot and status indicator lamp, and the front of pcb board has been arranged side by side 4 preceding slots; The reverse side of pcb board is provided with back slot and status indicator lamp.
2, according to claim 13 change the 4SAS hard disk backboards, it is characterized in that four jiaos of ends of pcb board and middle part, two ends are provided with screw.
