虚拟磁盘备份过程中，存储阵列的资源将从处理 I/O 活动转移至完成虚拟 磁盘备份。这将影响存储阵列的整体性能。创建新的虚拟磁盘备份时，会 定义备份优先级以确定将多长的控制器处理时间从 I/O 活动转移至虚拟磁 盘备份操作。

设置备份优先级

可使用 Copy Manager （备份管理器）选择对选定备份对完成虚拟磁盘备 份的速率。可在以下任意时刻更改备份对的备份优先权：

•开始操作虚拟磁盘副本之前

•当虚拟磁盘备份所处状态为 In Progress （正在进行）时

•重新创建虚拟磁盘备份时

设置备份优先权：

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在表格中选择一个或多个备份对。

3选择 Change （更改） → Copy Priority （备份优先权）。 将显示 Change Copy Priority （更改备份优先权）窗口。

4在 Copy priority （备份优先权）区域中，根据系统的性能需求选择相 应的备份优先权。

注：备份优先权共分 5 个级别：最低、低、中、高和最高。如果备份 优先级设置为最低级别，则会最优化 I/O 活动而虚拟磁盘备份将需要较 长的时间。

停止虚拟磁盘备份

您可以停止处于 In Progress （正在进行）状态、Pending （挂起）状态或 Failed （故障）状态的虚拟磁盘备份操作。停止处于 Failed （故障）状态 的虚拟磁盘备份将清除为存储阵列显示的 Needs Attention （需要注意） 状态。

停止虚拟磁盘备份时，请谨记以下原则：

•要使用该选项，请在 Copy Manager （备份管理器）中仅选择一个备份对。

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.
