Hierarchical storage server

Abstract

The invention provides a hierarchical storage server, comprising: a chassis, the interior of which is divided into a computing layer and a storage layer by a cross section; the computing layer is provided with a mainboard, an external interface card and a first heat dissipation module; the storage layer is provided with a storage tray, a second heat dissipation module and a power supply module; a storage medium is arranged on the storage tray, and the storage medium is in communication connection with the mainboard; and the mainboard is electrically connected with the power supply module. According to the method, the number of the storage media can be designed to the maximum extent in a limited space, upgrading development work can be independently carried out according to time points for a mainboard which is frequently iteratively upgraded, the original structural form of the storage layer is kept, re-development is not needed, the development period is shortened, the development cost is reduced, and the storage media and the external interface card are both designed in the front window. Maintenance personnel can carry out maintenance in a cold air area, the maintenance experience of the product is improved, the heat dissipation module can be designed according to a mode supporting hot plug maintenance, and maintenance of the heat dissipation module is facilitated.

Description

technical field [0001] The invention belongs to the technical field of servers, and in particular relates to a layered storage server. Background technique [0002] At present, major Internet operators have a strong demand for storage server products, which are mostly used for data backup, and the number of hard disks in the products ranges from more than ten to hundreds of hard disks. For storage server products, our common server types include JBOD products that do not have computing nodes but serve as storage pools. Such products cannot run independently and must be run with general servers that include computing units. The JBOD product is not a complete product. It can be used as an accessory product of the general main server and as an external storage space. This product does not have complete functions. Compatibility development and compatibility testing need to be done again after product development and matching with different products. The development time is long...

AI Technical Summary

Problems solved by technology

Even in a 4U size space, the number of hard drives on the front and rear windows can only support a maximum of 36 3.5-inch hard drives

And there is another biggest disadvantage of using a general-purpose server as a storage server. When the product is iteratively upgraded, the computing unit in the server—the motherboard needs to be redeveloped with the product iteration, because each generation of the motherboard will have differences, so the server's internal The size and space allocation also needs to be adjusted accordingly, so the server chassis will also be re-designed with the iterative upgrade of the product, wasting resources

The biggest disadvantage of a general-purpose server as a storage server is that the storage area is occupied more, the hard disk space is small, and the number of hard disks is small, so it can only be used as a small storage model

Secondly, the front window and the rear window are respectively occupied by the storage medium and the external interface. The heat dissipation module—the fan can only be built in. When the fan is built in, it is difficult to achieve live thermal maintenance, and the maintainability is poor.

Thirdly, when the motherboard encounters an iterative upgrade, in order to adapt to the new motherboard size, the server product often needs to be redeveloped, the development cycle is long, and the development cost is high.
