Abstract

The invention provides an implementation method of on-line upgrading firmware in a solid state hard disk, which is applied to the solid state hard disk, comprising the following steps: receiving a firmware upgrading command sent by a host; when it is judged that the mirror file in the solid-state upgrade command is complete, storing the mirror file; setting the state of PCIe Unit in the solid state drive to CRS state; judging whether the CRS state is successfully set according to the message reception status of PCIe Unit; if so, reading and writting the mirrored file to each CPU of the solid state drive. Therefore, this method can replace SSD firmware without power-down and power-up processing to SSD, thus ensuring the normal operation of enterprise equipment and the continued availabilityof services and services. The invention also provides a system for realizing on-line firmware upgrading in a solid-state hard disk, the solid-state hard disk and a computer-readable storage medium, all of which have the beneficial effects mentioned above.

Description

technical field [0001] The present application relates to the technical field of SSD, and in particular to a method, system, solid state hard disk and computer-readable storage medium for implementing online upgrade of firmware in a solid state hard disk. Background technique [0002] Firmware (FW, Firmware) upgrade refers to replacing the firmware in SSD (Solid State Disk, solid state drive). Through firmware replacement, SSD functions can be improved, SSD stability can be enhanced, and SSD vulnerabilities can be patched. However, ordinary firmware upgrades require SSD Power off and then power on, you need to shut down and restart the host. In a real usage scenario, this requirement often means service suspension and business interruption, which means negative impact on the brand and direct economic loss for the enterprise. [0003] Therefore, it is a technical problem to be solved by those skilled in the art how to replace the SSD firmware without powering off the SSD and...
