Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application discloses a storage server node, which comprises a plurality of rows of NVME SSD, wherein each row of NVME SSD supports the up-and-down stacking; and a cover plate used for ensuring the sealing performance of a system heat dissipation air duct of the storage server node is arranged between any two adjacent NVME SSDs.

It can be seen that, the storage server node of this embodiment supports multiple rows of NVME SSDs, each row of NVME SSDs supports stacking up and down, a cover plate capable of ensuring the sealing performance of the system heat dissipation air duct is disposed between every two adjacent rows of NVME SSDs, and the sealing performance of the system heat dissipation air duct is ensured by the above cover plate design, so that after the u.2tray is drawn out, the forced convection state can be maintained in the u.2tray regardless of whether the front row U.2, the currently maintained U.2, or the rear row U.2 is provided, thereby prolonging the thermal maintenance time of the NVME SSDs and improving the reliability and maintainability of the product.

In this embodiment, a cover plate fixing structure is disposed on a chassis wall of the storage server node, and is used to fix the cover plate. In particular, the center of the cover plate can be fixed on the wall of the chassis.

Further, in order to implement the turnover maintenance of the NVME SSD, in this embodiment, a turnover structure may be disposed on each row of the NVME SSD, and the corresponding NVME SSD is turned over by the turnover structure, so as to implement the turnover maintenance.

Further, in order to ensure that the NVME SSD flexibly turns over while maintaining the sealing performance of the system cooling air duct, the soft and sealed brushes may be disposed at the joint of the cover plate and each row of NVME SSD.

Further, in order to reduce the static electricity carried on the brush, a static electricity eliminator is further disposed on the storage server node of this embodiment, and is used for eliminating the static electricity carried on the brush. For example, an ion blower gun may be provided on the storage server node for generating positive and negative ions that neutralize static electricity. Preferably, the ion air gun may be specifically disposed at an upper air inlet of the system heat dissipation air duct.

Further, the brush can be prepared by an antistatic material, so that the brush can generate no static electricity or less static electricity when the NVME SSD is turned over for maintenance.

Furthermore, in order to prevent the cover plate from silting up due to the heat in the case caused by poor heat conductivity, the cover plate in this embodiment preferably adopts a metal cover plate.

Referring to fig. 1, the storage server node in fig. 1 is a high density U.2 storage server node, and the high density U.2 storage server node supports multiple rows U.2 (i.e., NVME SSDs), each row supporting one above the other. A cover plate is designed between two rows of NVME SSDs, the center of the cover plate is fixed on the wall of a storage node case, and soft and sealed brushes are arranged on two sides of the cover plate, so that the NVME SSDs can be flexibly turned over and the sealing performance of a system heat dissipation air duct is guaranteed. When the NVME SSD is maintained in a hot mode, the U.2train is drawn out, the 2 NVME SSDs which are stacked up and down are turned over upwards by 45 degrees, and then the 2 NVME SSDs are maintained.

Referring to FIG. 2, FIG. 2 is a schematic diagram of a duct design for a high density U.2 storage server node. When the u.2tray is pulled out, the front row U.2 will not be protected by the fan, and the forced convection heat dissipation mode is changed into the natural convection heat dissipation mode, so the front row U.2 must be able to maintain the forced convection state to protect the front row U.2 and meet the thermal maintenance time requirement. By adopting the system design scheme, the sealing performance of the system heat dissipation air duct can be ensured through the design of the cover plate and the hairbrush. After the U.2train is drawn out, U.2 at the front row can keep the same air channel in the case as the U.2train, and the forced convection state is maintained by drawing air from the bottom of the NVME SSD so as to solve the problem of heat dissipation; in fig. 2, a group of 2 NVME SSDs to be maintained is turned over, and an inclined air duct is maintained, so that the forced convection state is maintained through the air duct to solve the heat dissipation of the NVME SSDs to be maintained. In conclusion, the long-time hot plug maintenance of the high-density U.2 storage server nodes is satisfied through the above design.
