注：如果用作备份源的快照虚拟磁盘处于激活状态，源虚拟磁盘性能会因 写入同时复制 （copy-on-write）操作而降级。备份完成时，快照将被禁用并 且源虚拟磁盘的性能将恢复。尽管快照被禁用，但存储库基础构架和备份关 系保持不变。

为 MSCS 共享磁盘创建虚拟磁盘备份

要为 Microsoft Cluster Server (MSCS) 共享磁盘创建虚拟磁盘备份，请先 创建虚拟磁盘快照，然后将快照虚拟磁盘用作虚拟磁盘备份的源。

注：不使用快照虚拟磁盘，试图直接为 MSCS 共享磁盘创建虚拟磁盘备份， 会出现以下错误：

The operation cannot complete because the selected virtual disk is not a source virtual disk

candidate. （由于选定虚拟磁盘不能用作源虚拟磁盘，因此操作 无法完成。）

注：创建快照虚拟磁盘时，请将快照虚拟磁盘映射至群集中的唯一节点。 将快照虚拟磁盘映射至主机组或群集中的两个节点时，允许两个节点并发访 问数据可能会导致数据损坏。

虚拟磁盘 读 / 写权限

虚拟磁盘备份完成后，目标虚拟磁盘将自动变为对主机只读。如果虚拟磁 盘备份操作状态为 Pending （待定）或 In Progress （正在进行）或者在 完成备份之前操作失败，则目标虚拟磁盘将拒绝读写请求。如果由于以下 原因您要将数据保留在目标虚拟磁盘上，请保持目标虚拟磁盘的 Read- Only （只读）处于启用状态：

•如果您正使用目标虚拟磁盘进行备份。

•如果您正使用目标虚拟磁盘上的数据以将其复制回已禁用或出现故障 的快照虚拟磁盘的源虚拟磁盘。

如果您决定在虚拟磁盘备份完成后不将数据保留在目标虚拟磁盘上，则请 将目标虚拟磁盘的写保护设置更改为 Read/Write （读 / 写）。

设置目标虚拟磁盘读 / 写权限：

1在 AMW 中，选择 Virtual Disk （虚拟磁盘） → Copy Manager

（备份管理器）。

将显示 Copy Manager （备份管理器）窗口。

2在表中选择一个或多个备份对。

配置：高级功能—虚拟磁盘备份

MD3620F, MD3600f specifications

Dell's MD3620F and MD3600F storage arrays are designed for businesses seeking dependable, high-performance storage solutions tailored to meet the demands of modern data management. These models offer a blend of scalability, efficiency, and advanced features, making them well-suited for a range of applications, from virtual environments to critical database operations.

One of the primary features of the MD3620F and MD3600F is their support for a hybrid storage architecture. This approach allows organizations to combine flash storage with traditional hard disk drives (HDDs) to optimize performance and cost. The MD3620F focuses heavily on all-flash configurations, delivering exceptional speed and lower latency, ideal for I/O-intensive workloads.

Scalability is another hallmark of these storage solutions. The MD3600F allows users to scale up to 120 drives, providing robust capacity to meet growing data needs. The MD3620F is engineered for environments where data availability and speed are paramount, with support for high IOPS (Input/Output Operations Per Second) and consistent performance under stress.

In terms of data management, both systems integrate with Dell’s proprietary software, which enhances operational efficiency through features like automated tiering. This technology optimizes data placement between different storage types based on access frequency, ensuring that hot data is readily available while reducing costs associated with less critical data.

Reliability is crucial for businesses that depend on their storage systems. The MD3620F and MD3600F come equipped with advanced data protection mechanisms, such as RAID support, which safeguards against data loss, and snapshot capabilities that provide point-in-time copies of data. Moreover, these solutions include hot-swappable components, ensuring minimal downtime for maintenance and repairs.

Connectivity is also a strong suit of these storage arrays. They support multiple connectivity options, including SAS and iSCSI, allowing for flexible integration into existing IT infrastructures. This adaptability enhances their appeal to a wide range of enterprise environments.

In summary, the Dell MD3620F and MD3600F stand out as robust storage solutions with a combination of hybrid and all-flash configurations, scalability, advanced data management tools, and enhanced reliability features. These characteristics make them ideal for organizations looking to enhance their data storage capabilities while maintaining high performance and efficiency.
