目标虚拟磁盘

开始虚拟磁盘备份后，目标虚拟磁盘会保留来自源虚拟磁盘的数据的备份。可 选择是否使用现有虚拟磁盘或创建新的虚拟磁盘作为目标虚拟磁盘。如果选择 现有虚拟磁盘作为目标，则会覆盖目标上的所有数据。目标虚拟磁盘可以是标 准虚拟磁盘，也可以是出现故障或已禁用的快照虚拟磁盘的源虚拟磁盘。

注：目标虚拟磁盘的容量必须等于或大于源虚拟磁盘。

在开始磁盘备份过程时，必须定义完成备份的速率。如果赋予备份过程最高 的优先级，那么对 I/O 性能会稍有影响，而如果赋予其最低的优先级，则完 成备份过程的时间将更长。可在磁盘备份进行过程中更改备份优先级。

虚拟磁盘恢复

可使用 “编辑主机服务器到虚拟磁盘映射”功能从备份虚拟磁盘恢复数 据。该功能可从主机服务器取消映射原始的源虚拟磁盘，然后将备份虚拟磁 盘映射至同一主机服务器。

请确保记录了用于提供源虚拟磁盘的访问权限的 LUN。当为目标 （备份） 虚拟磁盘定义主机服务器到虚拟磁盘的映射时需要该信息。此外，在开始 虚拟磁盘恢复程序之前，务必停止到源虚拟磁盘的所有 I/O 活动。

同时使用快照和磁盘备份

快照虚拟磁盘可与虚拟磁盘备份高级功能一起使用，以备份相同存储阵列 上的数据，或将快照虚拟磁盘上的数据恢复到其原始的源虚拟磁盘。

您可以通过以下方式从虚拟磁盘备份数据：

•获取数据的时间点快照 （联机）

•使用虚拟磁盘备份将数据复制到另一个虚拟磁盘 （脱机）

可以选择快照虚拟磁盘作为虚拟磁盘备份的源虚拟磁盘。该配置是应用快 照虚拟磁盘功能的最佳方式之一，因为其可实现完整的备份，而且对存储 阵列 I/O 没有任何影响。

虚拟磁盘备份时，不能使用快照库虚拟磁盘作为源虚拟磁盘或作为目标虚 拟磁盘。如果在虚拟磁盘备份时，将源虚拟磁盘选作目标虚拟磁盘，则必 须禁用与源虚拟磁盘相关的所有快照虚拟磁盘。

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.
