In home setups, RAID is usually not needed, except for people who require exceptional performance or a very high level of redundancy.
RAID通常不需要在本地安装,除非人们想要额外的性能或非常高的冗余水平。
MongoDB provides replication features in a master-slave configuration (similar to MySQL) for the purposes of failover and redundancy, ensuring a high level of consistency between nodes.
为了实现故障转移和冗余,MongoDB在主从配置中提供了复制特性(类似于MySQL),从而确保节点之间的高度一致性。
Based on this technique, this paper proposes a high-availability data objects placement algorithm with mirroring, which groups objects into redundancy sets by using RAID at the algorithm level.
借鉴RAID的方法,在算法一级实现数据的冗余分布,提出基于镜像的高可用数据对象布局算法。
