For example, an array with three 300 GB drives and a 750 GB drive would be viewed as being the same size as an array with four 300 GB drives since the 750 GB drive is seen as a 300 GB drive.Expand array has the following options:Expansion TypeFor arrays that contain RAID 50 or RAID 60 logical drives, array expansion is constrained by the number of drives in the array and the number of parity groups in the existing logical drives. The transformation type refers to the different methods that apply to these logical drives:Increase Number of Parity Groups: the required number of physical drives will be added to form new parity group(s) for the array.Increase Number of Drives in Each Parity Groups: the required number of physical drives will be added evenly to each existing parity group.The notes on the top of the page will tell you how many drives are needed for each transformation type.Physical Drive SelectionSelect the physical drives that you want to use in the array from the unused drives listed.扩容：通过向现有阵列添加当前现有的未分配驱动器来增加阵列的容量。注意: 只应将相同大小（在 10% 以内）的物理驱动器添加到同一阵列，因为阵列中的所有驱动器都减少为最小物理驱动器的大小。 例如，具有三个 300 GB 驱动器和一个 750 GB 驱动器的阵列会被视为与具有四个 300 GB 驱动器的阵列大小相同，因为 750 GB 驱动器会被视为 300 GB 驱动器。扩展阵列有下列选项: 扩展类型 对于包含 RAID 50 或 RAID 60 逻辑驱动器的阵列，阵列扩展受到阵列中的驱动器数和现有逻辑驱动器中的奇偶校验组数的约束。 转换类型是指适用这些逻辑驱动器的不同方法：增加奇偶校验组数： 添加所需数量的物理驱动器，为阵列形成新的奇偶校验组。增加各奇偶校验组中的驱动器数： 向每个现有奇偶校验组均匀地添加所需数量的物理驱动器。页面顶部的说明将告知您每种转换类型需要多少个驱动器。物理驱动器选择:从未使用驱动器列表中选择要在阵列中使用的物理驱动器。 Move drive移动阵列The Move Array operation allows you to transfer the contents of a disk array from one set of physical drives to a second set of physical drives. Please note the following conditions and restrictions for the Move Array operation:The destination physical drive set must have the same number of elements as the source physical drives set.The array type (SAS or SATA) must remain the same.The destination drive(s) must have enough capacity to hold all the logical drives present in the source array.Note: As is the case with array creation and expansion, the usable space in all drives will be reduced to the size of the smallest physical drive in the destination disk set.使用“移动阵列”操作可以将磁盘阵列的内容从一组物理驱动器转移到另一组物理驱动器。 请注意，“移动阵列”操作有以下条件和限制：目标物理驱动器集与源物理驱动器集的元素数必须相同。阵列类型（SAS 或 SATA）必须保持不变。目标驱动器必须有足够的容量来容纳源阵列中的所有逻辑驱动器。注意: 像创建和扩展阵列时一样，所有驱动器中的可用空间将缩减至目标磁盘集中最小物理驱动器的大小。 Mirrir array镜像阵列The Mirror Array operation allows you to double the number of data drives in the array and convert all logical drives in the array to RAID 1, or RAID 1+0.This option is only available if the array contains only RAID 0 drives.When the total number of data drives in the resulting array is 2, the resulting RAID level is RAID 1. When the total number of data drives is 4 or more, the resulting RAID level is RAID 1+0.Note: Some controllers may not support this option or may require a license key to enable this feature.镜像阵列使用“镜像阵列”操作可以让阵列中的数据驱动器数量倍增，并将阵列中的所有逻辑驱动器转换为 RAID 1 或 RAID 1+0。仅当阵列仅含 RAID 0 驱动器时，此选项才可以使用。最终产生的阵列中的数据驱动器总数为 2 时，最终的 RAID 级别为 RAID 1。数据驱动器总数为 4 个或更多时，最终的 RAID 级别为 RAID 1+0。注意: 有些控制器可能不支持此选项，或者需要许可密钥来启用此功能。Shrink Array收缩阵列The Shrink Array operation allows you to remove drives from an existing array. The following conditions apply:The array must have enough free space to accommodate all existing logical drives.You may not remove drives from the array if the resulting number of drives will not support the fault tolerance (RAID level) of any existing logical drive. For example, if you have an array with 4 physical drives and a RAID 5 logical drive, you may remove at most 1 drive since RAID 5 requires at least 3 physical drives.If the array contains a RAID 1+0 logical drive, you may only remove an even number of drives.If the array contains a compound RAID (RAID 50 or RAID 60) logical drive, drives may only be removed in multiples of the number of parity groups. For example, an array with 10 physical drives and a RAID 50 logical drive may be shrunk by removing 2 or 4 disks only.Note: Some controllers may not support this option or may require a license key to enable this feature.使用“收缩阵列”操作可以从现有阵列中删除驱动器。 以下条件适用：阵列必须具有足够的可用空间来容纳所有现有逻辑驱动器。如果生成的驱动器数不支持任何现有逻辑驱动器容错（RAID 级别），则您可能不能从阵列中删除驱动器。 例如，如果阵列具有 4 个物理驱动器 和一个 RAID 5 逻辑驱动器，您最多可以删除 1 个驱动器，因为 RAID 5 需要至少 3 个物理驱动器。如果阵列包含一个 RAID 1+0 逻辑驱动器，则只能删除偶数个驱动器。如果阵列包含复合 RAID（RAID 50 或 RAID 60）逻辑驱动器，则只能按奇偶校验组数的倍数删除驱动器。 例如，含 10 个物理驱动器和一个 RAID 50 逻辑驱动器的阵列收缩时只能删除 2 个或 4 个磁盘。注意: 有些控制器可能不支持此选项，或者需要许可密钥来启用此功能。Replace Array更换阵列 The Replace Array operation allows you to transfer the contents of an array to an existing empty array or a new array. All logical drives from the source array will be transferred. The original array will be deleted and its data drives will be freed as unassigned drives. The drive types at source and destination arrays can be different. Please note the following conditions and restrictions for the Replace Array operation:The destination array must have the same number of physical drives as the source array to be replaced.Both the source and the destination arrays must be in OK state. All the existing logical drives in the source arrays must be in OK state.The destination array must have enough capacity to hold all the logical drives present in the source array.Note: Replacing an array is a time-consuming operation for the following reasons: The data in every logical drives of the source array has to be copied to the destination array; the co
