•虚拟磁盘备份停止时，所有映射的主机都具有对源虚拟磁盘的写入权 限。如果数据已写入源虚拟磁盘，则目标虚拟磁盘上的数据与源虚拟 磁盘上的数据不再匹配。

要停止虚拟磁盘备份，请完成以下步骤：

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在表格中选择备份对。

3选择 Copy （备份） → Stop （停止）。

4单击 Yes （是）。

重新复制虚拟磁盘

在您停止虚拟磁盘备份并要再次启动虚拟磁盘备份时或者在虚拟磁盘备份 出现故障时，可以重新备份虚拟磁盘。

Recopy （重新备份）选项将覆盖目标虚拟磁盘上的现有数据并使目标虚 拟磁盘对主机为只读。此选项会使所有与目标虚拟磁盘关联的快照虚拟磁 盘 （如果有）失败。

准备主机服务器以重新复制虚拟磁盘

注：在创建源虚拟磁盘的新副本之前，请停止所有数据访问 (I/O) 操作，或 暂停向源虚拟磁盘 （和目标磁盘，如果有）传输数据，以确保您捕获源虚 拟磁盘的准确时间点映像。关闭所有应用程序 （包括 Windows Internet Explorer），以确保已停止所有 I/O 活动。

注：在 Windows 中删除关联虚拟磁盘的驱动器号或在 Linux 中卸载虚拟驱动 器将有助于为虚拟磁盘备份获得可靠的驱动器副本。

为现有副本对创建新的虚拟磁盘副本之前，主机服务器和要重新复制的关 联虚拟磁盘必须处于正确的状态。请执行以下步骤准备主机服务器和虚拟 磁盘：

1停止对源虚拟磁盘和目标虚拟磁盘的所有 I/O 活动。

2使用 Windows 系统将高速缓存刷新到源虚拟磁盘和目标虚拟磁盘 （如 果已安装）。在主机提示符处，键入

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.
