Of course, according to actual needs, more than Three-layer tray structure. Specifically, the server storage structure includes a chassis base 1 and a tray 2 . A plurality of tray rollers 101 are provided on the inner walls of both sides of the chassis base 1 , wherein the upper two layers of trays 2 are placed on the tray rollers 101 , and the lower layer trays 2 rely on the chassis base 1 . The fixed-point convex hull on the support tray 2 is pulled out.

In this way, the server storage architecture adopts the tray rollers 101 to replace the pull-out ball slide rails. Due to the limitation of the width of the chassis, the general ball slide rails cannot meet the thickness requirement. Therefore, the rolling characteristics of the tray rollers 101 are used to replace the slide rails. The smoothness of the pulling of the tray 2 can be ensured, and at the same time, the price of the tray roller 101 is relatively cheap, which can save a certain cost compared with the sliding rail.

It should be noted that the tray 2 needs to support the arrangement of four horizontal hard disks, the spanning of the IO board, and the routing of the side box ear wires. The width space of the chassis is limited, the space on the left is only 5mm, the gap on the right is 3mm, and the ball slides. The thickness of the rail cannot be supported. Therefore, each layer relies on 22 tray rollers 101 on both sides to replace the slide rail to support the pulling operation and maintenance of the tray 2; while the bottom tray 2 relies on the fixed-point convex hull design on the base to replace the roller to support and slide.

It should be noted that the tray 2 includes a tray strut 201, a front middle frame 217 and a rear middle frame 218.

The rod 201, the front middle frame 217 and the rear middle frame 218 are connected as a whole to form a tray structure with a hollow structure in the middle.

In this way, the tray 2 adopts the design of left and right struts and front and rear middle frame die-casting parts, which can improve the strength of the tray 2 and prevent it from being twisted and deformed. The case where tray 2 is pulled out; the hollow design in the middle can reduce the value of the height of tray 2, and can achieve an ultra-thin design with the same thickness as the hard disk, paving the way for the design of the 2U storage 3-layer tray structure.

That is to say, the above-mentioned setting method can reduce the height of the tray 2. At the same time, the ultra-thin "mouth"-shaped hollow design can reduce the thickness space of the tray 2, achieve an ultra-thin structure design, and can also achieve a height difference. Extreme design, so that the hard disk can be assembled without tools, and the efficiency of manufacturing and operation and maintenance can be improved.

In this way, within the height of 87.5mm of 2U server, it supports the structure design of 3-layer hard disk tray module, and the height of each tray is 26.6mm; the hollow design of die-casting parts, left and right struts and die-casting parts is adopted to make the hard disk slot All hollowed out, the height can be compressed to the limit to achieve ultra-thin design; at the same time, the tray 2 is formed as a whole under the connection of sheet metal parts, the structural strength is reliable, and deformation and distortion will not occur. The problem of thin compression, and secondly, it can also avoid the pulling effect on other layers after the position of the hard disk sinks and deforms.

On the basis of the above, handles 216 are provided on both sides of the front end of the tray brace 201, and a hard disk backplane 206 is provided in the middle of the tray 2.
