Specifically, a hard disk 7 frame is arranged on the chassis, and a slot 6 is formed on the hard disk 7 frame.

The server of the third aspect of the present invention comprises or uses the hard disk module of the second aspect of the present invention, and therefore has the advantage of ensuring that the connection of the hard disk carrier to the hard disk 7, and the connection of the hard disk carrier to the slot 6 of the chassis, can be done at the first end of the hard disk 7. Since the hard disk bracket is fixed at the first end of the hard disk 7, the hard disk bracket can be partially positioned outside the slot 6 when the hard disk 7 is inserted into the slot 6, thereby reducing the occupation of space along the length direction of the hard disk 7 by the hard disk bracket.

The hard disk bracket of the server in the embodiment of the invention only needs to occupy the space in the length direction of the hard disk 7, and does not need to extend between the hard disk 7 and the slot 6 of the case, so that the width or thickness of the hard disk 7 is increased, and the situation that the arrangement of the hard disk bracket occupies the space in the width or thickness direction of the hard disk 7, so that the space in the width or thickness direction of the hard disk 7 is limited in use range, or the layout space of devices on the backboard of the hard disk 7 is limited is avoided. The problem that the hard disk bracket limits the use range of the space in the width direction of the hard disk 7 in the related art and reduces the number of the hard disks 7 which can be supported by the server can be solved.
