Technical Field

With the development of information industry, the data volume of information to be stored in a computer has been rapidly expanding, and the rapid development of external storage of a computer has been promoted, and the development of a separate industry, the storage industry, has been advanced. When enough storage media cannot be installed in the computer host case, the storage capacity is expanded by expanding the case or the storage servers connected through a network are expanded, so that an external storage subsystem is formed.

However, the external storage subsystem of the existing computer system is designed based on a standard chassis, and the controller in the external storage subsystem is designed with the motherboard or is a standard board card, and cannot independently take out the external storage subsystem. These problems can create design technical and time difficulties for some computer designs that are custom-built with special requirements, which can be a challenge for unit technicians if the controller is designed with the motherboard, which requires controller knowledge; if the controller in the external storage subsystem adopts a standard board card, the volume of the chassis is large, and the single-side contact of the golden finger of the standard PCIE board card cannot resist the application under the vibration condition, and the card is required to be connected with the backboard, so that unreliable factors are increased.
