Description

Hard disk array device

technical field

The utility model relates to the technical field of storage devices, in particular to a high-density hard disk array device.

Background technique

With the development of information technology, the demand for data storage is increasing, especially the demand for storage capacity of video data is particularly obvious. In order to meet the demand for storage capacity, on the one hand, hard disk manufacturers continue to develop large-capacity hard disks to meet market demand; on the other hand, storage device manufacturers manufacture storage devices that support a larger number of hard disks. A hard disk array is a storage device that places several hard disks together. Since a hard disk array needs to occupy a large space, increasing the number of hard disks means taking up more space. Therefore, the number of hard disks per unit volume becomes one of the key characteristics of a hard disk array. .

The hard disks of current storage devices generally use 3.5-inch hard disks. The hard disks are installed on one side of the cabinet, and some high-end products are installed on both sides of the cabinet to increase the density of hard disks.

FIG. 1 is a structural diagram of a single-sided hard disk horizontal insertion solution in the prior art. As shown in the figure, the hard disk 120 in the cabinet 110 is installed in such a way that the heat dissipation surface is parallel to the ground, and the hard disk insertion and removal direction is horizontal. This solution is the mainstream installation method of hard disk arrays. The front of the cabinet is hard disk, the back is redundant control module and redundant power fan module, and the backplane is placed vertically in the middle of the cabinet. In the hard disk array using this solution, the hard disk density of the 3U high storage device is less than 6Disk/U, and the hard disk density of the 2U high and 4U high storage device is 6Disk/U. Among them, 1U=4.445cm, Disk/U refers to the ratio of the number of hard disks in a standard 19-inch rack storage device to the height occupied by the device. The higher the ratio, the higher the hard disk density.

FIG. 2 is a structural diagram of a single-sided hard disk vertical insertion scheme in the prior art. As shown in the figure, the hard disk 220 in the cabinet 210 is installed in such a way that the heat dissipation surface is perpendicular to the ground, and the hard disk insertion and removal direction is horizontal. This solution is also a mainstream installation method for hard disk arrays. It is similar to the horizontal hard disk insertion solution shown in Figure 1. It has hard disks on the front, redundant control modules and redundant power fan modules on the back, and the backplane is also vertically placed in the middle of the cabinet. . In the hard disk array using this solution, the density of the hard disk in the cabinet is generally 14Disk/3U, 15Disk/3U or 16Disk/3U, that is, the highest density is about 5.3Disk/U; in addition, this solution requires a backplane PCB (Printed Circuit Board, printed circuit board ) open a large number of cooling holes, which will lead to a decrease in structural strength.

Figure 3 is a structural diagram of the vertical insertion scheme for hard disks installed on both sides in the prior art. The pulling direction is horizontal; the airflow enters from both sides of the cabinet, and the air outlet 330 is set on the top of the cabinet; the power module 340 and the storage service processing module 350 are installed in the same direction as the hard disk 320, and the plugging direction is also the same. The hard disk array using this solution must use a dedicated cabinet, and the special air duct design makes the heat dissipation capacity of hard disks of different heights unbalanced, and the hard disk density can only reach 48Disk/7U, not exceeding 7Disk/U.

Different from the above solutions, another way to increase the density of hard disks in the prior art is to use 2.5-inch hard disks instead, which can achieve 20Disk/2U. lower.

Detailed ways

Below with specific embodiment in conjunction with accompanying drawing, the utility model is further described.

4 is a diagram of a hard disk array device according to an embodiment of the present invention. As shown in the figure, the hard disk array device in this embodiment includes a cabinet 410, a hard disk frame 420, a hard disk 430 and a backplane (not shown in the figure).

A slide bar 421 is installed on the side wall of the hard disk enclosure 420, which can slide on a high-strength shock-absorbing slide rail (not shown in the figure) installed on the inner wall of the cabinet 410; a limiting part should also be installed on the slide bar 421 and the slide rail, In order to prevent the hard disk enclosure 420 from sliding out of the cabinet 410 completely. The backplane is fixedly installed on the bottom of the hard disk frame 420, and is provided with a hard disk slot (not shown in the figure) for the vertical insertion of the hard disk 430 thereon. The hard disks 430 are arranged in a matrix and vertically inserted into the hard disk frame 420 through the slots on the backplane, while the heat dissipation surface of the hard disks 430 is parallel to the sliding direction of the hard disk frame 420 . In addition, the hard disk frame 420 also has a fixed structure (not shown in the figure) between the hard disk rows and/or hard disk columns of the hard disks arranged in a matrix to ensure the stability of the hard disk 430 in the horizontal direction.

Continuing to refer to FIG. 4 , in the above embodiment, the sliding direction of the hard disk enclosure 420 is shown by arrow A, and the plugging direction of the hard disk 430 is shown by arrow B. When it is necessary to perform hard disk insertion and removal operations, the hard disk frame 420 is first pulled out from the cabinet 410 along the slide rails, and then the hard disk 430 is inserted and removed from above the hard disk frame 420 .

Applying the hard disk array device of the present invention, the hard disk frame 420 shown in FIG. 4 can be built with 3-4 rows of 3.5-inch hard disks or 4-5 rows of 2.5-inch hard disks. When using a 3.5-inch hard disk, the hard disk density in a standard 19-inch 800mm cabinet can be increased from the highest 7Disk/U of the existing technology to 12Disk/U, while using a 2.5-inch hard disk can be increased from the highest 13.3Disk/U (40Disk/U) of the existing technology 3U) to 33.3Disk/U (100Disk/3U), greatly improving the hard disk density in the cabinet.

In order to achieve the purpose of heat dissipation of the hard disk array device, the front and rear walls of the hard disk enclosure 420 perpendicular to the sliding direction A are also provided with openings 422 for the cooling air to enter from the front of the cabinet 410 and the air to exit from the back of the cabinet 410. Since the heat dissipation air does not need to pass through the backplane, the air duct is smoother, and the backplane does not require a large number of openings, so the strength is guaranteed, and the high-speed signals in the backplane can be routed smoothly. In order to allow the airflow to better dissipate heat to the hard disk 430 through the air inlet, the fixed structure between the hard disk rows also needs to be opened instead of being sealed.

The hard disk array device in this embodiment further includes a fan module 440 , a power module 450 and a storage service processing module 460 , all of which are built in the hard disk enclosure 420 . The power module 450 and the storage service processing module 460 are located on the side of the hard disk enclosure 420 close to the inside of the cabinet 410; and the fan module 440 is inserted between the hard disk array and the power supply module 450 and the storage service processing module 460 , the plugging and unplugging method is the same as that of the hard disk 430, as shown by arrow C. In addition, the fan module 440 is built into the power supply module 450, or placed between the hard disk array and the air inlet can also achieve the purpose of heat dissipation; The redundant fan modules 430 are installed in each room, which is not a necessary technical feature of the present invention, so it will not be repeated here.

The above disclosures are only a few specific embodiments of the utility model, but the utility model is not limited thereto, and any changes conceivable by those skilled in the art should fall within the protection scope of the utility model.
