阵列中的每一个物理磁盘驱动器都表示为一个矩形，而这个矩形对应于阵列中某个物理位置的驱动器。
Each physical disk drive in the array is represented by a single rectangle and that rectangle corresponds with the physical location of the drive in the array.
所有上述技巧都适用于这些系统，但除此之外，您还需要确保Domino工作负载有效、平衡地分布到物理磁盘驱动器中。
All of the above techniques apply to such systems, but in addition, you need to make sure that the Domino workload is efficiently distributed and balanced among the physical disk drives.
它不能阻止由于硬件或磁盘驱动器故障、数据损坏或其它潜在物理灾难引起的数据丢失。
Nor does it protect you from situations where data has been lost due to a hardware or disk drive failure, data corruption, or other potential physical disasters.
