红帽全球峰会16.5. RAID 子系统
以下子系统组成了 RAID：
- 硬件 RAID 控制器驱动程序
- 硬件 RAID 控制器没有特定的 RAID 子系统。由于它们使用特殊的 RAID 芯片组，因此硬件 RAID 控制器有自己的驱动程序。使用这些驱动程序时，系统会检测 RAID 集作为常规磁盘。
mdraidmdraid子系统被设计为软件 RAID 解决方案。这也是 Red Hat Enterprise Linux 中软件 RAID 的首选解决方案。此子系统使用自己的元数据格式，称为原生 MD 元数据。它还支持其他元数据格式，称为外部元数据。Red Hat Enterprise Linux 10 使用带有外部元数据的
mdraid来访问 Intel Rapid Storage (ISW)或 Intel Matrix Storage Manager (IMSM)集以及存储网络行业关联(SNIA)磁盘驱动器格式(DDF)。mdraid子系统集通过mdadm程序进行配置和控制。
