Abstract
(EN)
A method, device and system for memory data migration. In the process of memory migration, the data is categorized into two portions according to the hot and cold degree of the data; the hot data is migrated directly, and the cold data is written into a shared storage device shared by memory devices. When a destination memory device needs to use the cold data, the cold data can be read directly from the shared storage device, so as to reduce the data volume required to be migrated to the destination memory device, thereby improving the efficiency of memory migration.
(FR)
L’invention concerne un procédé, un dispositif et un système de migration des données de mémoire. Lors du processus de migration de mémoire, les données sont classées en deux parties en fonction du degré « chaud » et « froid » des données ; les données chaudes sont amenées à migrer directement, et les données froides sont écrites dans un dispositif de mémorisation partagée partagé par des dispositifs de mémoire. Lorsqu'un dispositif de mémoire de destination a besoin d'utiliser les données froides, les données froides peuvent être lues directement à partir du dispositif de mémorisation partagée de manière à réduire le volume de données requises pour être amenées à migrer vers le dispositif de mémoire de destination, ce qui permet d'améliorer l'efficacité de la migration de mémoire.

一种内存数据迁移的方法,装置及系统。通过在内存迁移时,根据数据的冷热程度将数据分为两部分,将热数据直接迁移,将冷数据写入内存共享的共享存储设备中,目的内存在需要使用该冷数据的时候,可以从共享存储设备中读取,减少了需要迁移到目的端内存的数据量,从而加快内存迁移的效率。
