Abstract

The invention discloses a system upgrading method and apparatus, which can improve system upgrading efficiency. The method comprises the steps of loading a target component, wherein the target component is an upgrading component corresponding to a to-be-upgraded source component in a system; sending a first signal to a thread using the source component currently, wherein the first signal is used for indicating the suspension of the thread; after the suspension of the thread, synchronizing data of the source component to the target component; after the data of the source component is synchronized to the target component, replacing the source component with the target component; and after the source component is replaced with the target component, sending a second signal to the thread, wherein the second signal is used for indicating the recovery of the thread.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for upgrading a system. Background technique [0002] Information Technology (IT) storage devices are usually used in industries such as finance, medical care, education, and media assets. This industry is characterized by high load, high throughput, high reliability, and high serviceability.
