Solid state disk fault online processing method and solid state disk

Abstract

The invention discloses a solid state disk fault online processing method. The method comprises: a fault module with an error in a solid state disk informing a front-end module interacting with a hostin an interrupt mode; the front-end module reserving an interface with the host and sets an interface communicating with the fault module to be in a loopback mode; in the loop-back mode, the front-end module receiving a command issued by the fault module to the host, the fault module directly returning to complete the operation, and not executing the function corresponding to the command; and thefront-end module returning a pause to the host. The invention further discloses a solid state disk which is characterized in that the solid state disk is divided into a front-end module, an algorithmmodule and a rear-end module according to functions, and the algorithm module and the rear-end module internally comprise detection codes used for detecting internal errors of the modules. After thesolid state disk has a software logic fault, the connection interface of the fault module is set to be in a loop-back mode, so that the solid state disk is prevented from falling off, partial functions of the solid state disk are shielded, and fault diffusion is prevented.

Description

technical field [0001] The invention relates to the technical field of solid-state hard disks, in particular to an online processing method for solid-state hard disk failures and solid-state hard disks. Background technique [0002] With the development of technologies such as the Internet, cloud computing, and the Internet of Things, solid-state drives, as a new generation of storage, have been widely used. [0003] As the bottom end of the data center, solid-state drives carry the key task of storing data. According to different functions, the internal architecture of the SSD can be divided into different modules. Among them, the part used to interact with the host is the front-end module, and other modules of the SSD need to receive and execute commands issued by the host through the front-end module. However, due to the The interface to the upper layer is relatively simple, so from the perspective of the host, the SSD is a black box. Once a module inside the SSD fails, ...

According to different functions, the internal architecture of the SSD can be divided into different modules. Among them, the part used to interact with the host is the front-end module, and other modules of the SSD need to receive and execute commands issued by the host through the front-end module. However, due to the The interface to the upper layer is relatively simple, so from the perspective of the host, the SSD is a black box. Once a module inside the SSD fails, it is difficult to locate it accurately. If the faulty SSD is powered off and sent back to the manufacturer for positioning, it will inevitably The fault site will be lost and accurate information cannot be obtained
