Deciding on the number of data drives for each RAID array can be rather complex, since the number of drives in an array is not necessarily equal to the number of drives in which data is populated.
每个RAID阵列的数据驱动器数目的确定可能相当复杂，因为一个阵列中的驱动器数目并不一定等于进行数据填充的驱动器数目。
This is why a RAID-0 array of IDE disks can outperform the fastest SCSI or FC-AL drive on the market.
这就是IDE磁盘的RAID - 0阵列优于市面上最快的SCSI或FC -AL驱动器的原因。
The Distributed Replicated Block Device (DRBD) provides a networked version of data mirroring, classified under the redundant array of independent disks (RAID) taxonomy as RAID-1.
DistributedReplicatedBlockDevice (DRBD)提供一个网络版的数据库镜像，属于冗余磁盘阵列(RAID)RAID - 1类。
From a reliability standpoint, RAID-0 has the same characteristics as linear mode — the more drives you add to the array, the higher the probability of volume failure.
从可靠性的立场来看，RAID - 0模式与线性模式具有同样的特征——向阵列中添加的驱动器越多，卷的故障概率就越高。
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.
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。
Then, open it up and unplug one of the hard disks that make up your RAID-1 array.
然后，打开机箱，并断开组成RAID - 1阵列的一个硬盘。
If one of the RAID 0 devices malfunctions, the array will continue operating, using the parity device as a backup.
如果RAID0中的一块设备发生故障了，阵列将适用校验设备做备份继续运作。
Next, "nr-raid-disks" should specify the number of disks in your array.
接下来，“nr - raid - disks ”应指定您的阵列中的磁盘数目。
The loss of one hard disks in the RAID array result to an overall data loss .
损失一个硬盘，在阵列结果，以一个整体的数据丢失。
The loss of one hard disks in the RAID array result to an overall data loss .
