并按 <Enter> 键。有关详情，请参阅第 246 页上的 “SMrepassist 公 用程序”。

3为确保虚拟磁盘处于 Optimal （最佳）状态或 Disabled （已禁用）状 态，请选择 Summary （摘要）选项卡，然后单击 Disk Groups & Virtual Disks （磁盘组与虚拟磁盘）。

4在 Windows 中移除源磁盘和虚拟磁盘 （如果已安装）的驱动器号，或 在 Linux 中卸载虚拟驱动器，将有助于稳定地备份用于虚拟磁盘的驱 动器。否则，复制操作将报告已成功完成此任务，但复制的数据却不 会正确更新。

5请遵循操作系统的所有附加说明。不遵循这些附加说明可能会导致创 建的虚拟磁盘副本无法使用。

注：如果操作系统需要附加说明，可以在操作系统文档中找到相关说明。

重新备份虚拟磁盘

可使用 Copy Manager （备份管理器）为选定的源虚拟磁盘和目标虚拟磁盘 新建虚拟磁盘备份。如果已停止虚拟磁盘备份并想再次将其启动，或是虚拟 磁盘备份失败或已完成，则可使用此选项。虚拟磁盘备份会从新开始。

•可能丢失数据—重新复制操作会覆盖目标虚拟磁盘上的现有数据。

•可能丢失数据访问权限—当虚拟磁盘备份的状态为 In Progress （正在 进行）或 Pending （挂起）时，源虚拟磁盘仅可用于读取 I/O 活动。 完成虚拟磁盘备份之后便会批准写入请求。

重新备份虚拟磁盘时，请谨记以下原则：

•如果主机映射至源虚拟磁盘，则从创建上一个虚拟磁盘备份后，执行 重新备份操作时复制到目标虚拟磁盘的数据可能已更改。

•只在 Copy Manager （备份管理器）对话框中选择一个虚拟磁盘备份。 要重新备份虚拟磁盘：

1 停止针对源虚拟磁盘和目标虚拟磁盘的所有 I/O 操作。

2 卸载源虚拟磁盘和目标虚拟磁盘上的所有文件系统。

3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。

4在表格中选择备份对。

5选择 Copy （备份） → Re-Copy（重新备份）。

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.
