RAID - Z不是唯一可用于ZFS的磁盘阵列类型，镜像速度通常更快且消耗的内存更少，但需要等量的硬盘驱动器才能使用它。
RAID-Z is not the only type of disk array available to ZFS. Mirrors are usually faster and less memory-consuming, but require equal Numbers of hard drives to use it.
目标设备可以是硬盘或磁盘阵列系统。
A target device could be a hard disk or a disk array system.
这两种服务利用大量的数据，因此需要一个有能力有一个大机磁盘阵列，可提供10 TB的硬盘空间来启动，能够很容易扩展。
Both services utilize large amounts of data and therefore require a capable machine with a large disk array that provides 10 TB of disk space to start, with the ability to be easily extended.
