Description

Bracket assembly compatible with different specifications of hard disk air inlet quantity and server

Technical Field

The invention relates to the technical field of servers, in particular to a bracket assembly compatible with the air inlet quantity of hard disks with different specifications and a server.

Background

The front window of the server is usually a hard disk area, taking a 2U model as an example, and in the specification configuration of the product, 12 3.5 inch hard disks are usually supported in the front window (see fig. 17). The hard disk is fixed through the hard disk bracket and used as an independent module, can be inserted into a hard disk frame of a front window of the chassis and is connected with a rear hard disk backboard, so that a hot plug function is realized. The common hard disk size of the server is divided into a 3.5 inch hard disk and a 2.5 inch hard disk, the length of the 2.5 inch hard disk is 101.85mm (max), the width is 69.85mm, and the thickness is different from 5mm to 19.05 mm; the thickness of the conventional mass-used 2.5 inch hard disk is 9.5mm and 15 mm. The 3.5 inch hard disk has a length of 147.00mm and a width of 101.60mm, and the thickness of the hard disk is usually less than 26.10mm.

The physical form of the mechanical hard disk is a 3.5 inch hard disk, and the SSD of the solid state hard disk is a form of a 2.5 inch hard disk. Depending on the business application, such models typically have 3.5 inch hard disks mixed with 2.5 inch hard disks, mixed with 2.5 inch hard disks of different thickness. The power consumption of a common hard disk of a server is different from 10W to 25W, and the maximum power consumption of an E3.S hard disk reaches 70W along with the technical development. The difference of the thickness and the power consumption of the hard disk leads to the difference of the gap and the air inlet quantity which are required to be maintained for heat dissipation. And the slots are uniformly installed in the server case, so that the hard disk with various types and sizes can be supported simultaneously, and challenges are faced.

In the heat dissipation design of the server, the hard disk is used as a key component, and the heat dissipation performance of the hard disk influences the data service performance of the server. The existing server hard disk bracket supports a 3.5 inch hard disk to a 2.5 inch hard disk, is structurally simple and is fixed and locked by screws at two sides, but because the thickness of the 2.5 inch hard disk is different in specification and size, the thickness is different from 5mm to 19.05mm, and the air inlet quantity of the hard disk with different thickness is different. When discs with various sizes are mixed, the disc with large thickness has large hard disc impedance, small air inlet quantity, small hard disc impedance and large air inlet quantity. When multiple thick disks in the system are mixed, part of the disks have large air inlet quantity, excellent heat dissipation and low temperature, and part of the disks can give out high-temperature alarms due to small air inlet quantity, poor heat dissipation and high temperature. Taking fig. 18 as an example, a 2.5 inch solid state disk with a height of 15mm is mounted on the upper and lower 2 layers of hard disk slots, and a 2.5 inch solid state disk with a height of 9.5mm is mounted in the middle layer. As can be seen in the cross section, the air flow gap above a 2.5 inch solid state disk at 15mm height is 1mm and the air flow gap above a 2.5 inch solid state disk at 9.5mm height is 6.5mm. The system goes into wind position, and the windage flows to the position that windage is little in preference, for example, lower figure 6.5mm clearance place, and the influence that brings is: the air flow rate at the position of a 2.5 inch solid state disk with the height of 9.5mm is high, and the heat dissipation is sufficient; however, the air flow becomes small at the position of the solid disk with the height of 2.5 inches of 15mm, and the problem of high temperature reporting of the hard disk occurs.

The air flow gap above the 15mm high 2.5 inch solid disk 27 was 1mm and the air flow gap (duct height) above the 9.5mm high 2.5 inch solid disk 28 was also 1mm.

For the installation of a 3.5 inch hard disk, 4 screws are directly used for locking the two sides of the hard disk bracket 29, a 2.5 inch hard disk switching support 1 and an air quantity adjusting support 2,3.5 inch hard disk are not needed to be additionally used, the gaps between the upper surface and the lower surface of the hard disk and the gaps between the upper surface and the lower surface of the hard disk are the same, the wind resistance is the same, the air quantity is the same, and the heat dissipation efficiency is balanced.

The advantages are that: the same hard disk bracket 29 supports and installs a 3.5 inch hard disk with the height of 21.6mm, a 2.5 inch hard disk with the height of 9.5mm and a 2.5 inch hard disk with the height of 15mm, and has better universality. The 2.5 inch hard disk with two height specifications can be installed by using the same conversion bracket, and the normalized design reduces the material number of the bracket and reduces the turnover and material preparation cost in production operation. The air flow adjusting bracket automatically adjusts the air inlet quantity of the surface of the hard disk according to the height of the 2.5 inch hard disk; the same gap is kept, so that hard disks with different specifications are ensured to be inserted in a mixed manner in the same case. In the whole-row design of the hard disk of the storage server, the air inlet quantity of the hard disk with different thickness sizes is different, and the air flow equalization of the hard disk is particularly important for the heat dissipation design of the hard disk. Under the condition of fixed total air quantity of the fan, the air inlet and outlet quantity of the hard disk with different models can be reasonably distributed, and the optimal heat dissipation energy consumption ratio of the system can be exerted. The design can adjust the air inlet quantity according to the disc sizes with different thicknesses, and ensure that the air inlet of each hard disc of the system is uniform in flow, so that the temperature of each hard disc is ensured to be uniform. And the heat dissipation efficiency of the hard disk is improved.
