Embodiment Construction

[0021] The technical solutions in the present invention will be described below in conjunction with the accompanying drawings. In order to help those skilled in the art better understand the technical solutions of the present invention, some concepts involved in this application are firstly introduced.

[0022] The storage system referred to in the embodiments of the present invention may be a built-in storage system or an external storage system. The built-in storage system can also be called built-in storage, internal storage, etc. A built-in storage system is a storage system inside a computer device. The computer device can directly access the built-in storage system, read data stored in the built-in storage system, or write data into the built-in storage system. The plug-in storage system can also be called plug-in storage, external storage, etc. The computer equipment can be connected with the external storage system in a wired or wireless manner, so as to read data s...

Abstract

The present application provides a storage system and a storage control device. The storage system includes: a first clock device, configured to generate a first clock signal and send the first clock signal to the first storage control device and the second storage control device; The first storage control device is used to receive the first clock signal and send the first clock signal to the storage device; the second storage control device is used to receive the first clock signal and send the first clock signal to the storage device. device; a storage device, used for receiving the first clock signal from the first storage control device and the second storage control device; and performing data read and write according to the first clock signal. In this way, the loss of the disk caused by the failure of the clock signal to transmit the signal normally due to the pin failure is avoided.

Description

technical field [0001] The present application relates to the technical field of storage, and more specifically, to a storage system and a storage control device. Background technique [0002] In order to ensure the reliability of the storage device, the storage device is provided with two ports (ports), and the two ports are respectively connected to two controllers, and the two controllers are independently decoupled. If one of the two ports of the storage device fails, the corresponding controller will mark the storage device as faulty. This phenomenon can be called disk loss. The read and write channels of the storage device are changed from 2 to 1. This will affect the read and write performance of the storage device. [0003] Taking a storage device using an SFF-8639 interface as an example, the storage device has two ports, port A (port A) and port B (port B). The storage device can be connected to controller A through port A, and connected to controller B through...
