刚看到新闻上说，Linux Kernel 2.6.33将包含DRBD，DRBD 类似磁盘阵列的RAID 1，只不过 RAID 1是在一台电脑内，而DRBD是透过网络的！

DRBD(Distributed Replicated Block Device)是Linux平台上的分布式储存系统，由内核模块和相关脚本而构成，用以构建高可用性的集群。DRBD是以 GPL2 授权散布的自由软件！

DRBD® refers to block devices designed as a building block to form high availability (HA) clusters. This is done by mirroring a whole block device via an assigned network. DRBD can be understood as network based raid-1.
