重新创建快照虚拟磁盘

您可以重新创建先前已禁用的快照虚拟磁盘。

小心：可能丢失数据冗余 – 如果快照虚拟磁盘处于 Optimal （最佳）状态， 则会在重新创建它之前先将其禁用。此操作会使当前快照无效。

重新创建快照虚拟磁盘时，请谨记以下重要原则：

• 要正确地重新创建快照虚拟磁盘，请遵照操作系统的说明。

注：否则可能会导致所创建的快照虚拟磁盘不可用。有关详情，请参

（PowerVault Modular Disk Storage Manager 联机帮助）主题。

•要使用该选项，快照虚拟磁盘必须处于 Optimal （最佳）或 Disabled （已禁用）状态。

•使用该选项时，会使用先前配置的快照名称参数和快照库虚拟磁盘。 重新创建快照虚拟磁盘：

1 在 AMW 中，选择 Logical （逻辑）选项卡并选择一个快照虚拟磁盘。

2选择 Virtual Disk （虚拟磁盘） → Snapshot （快照） → Re-create

（重新创建）。

3键入 yes，然后单击 OK （确定）。

快照回滚

快照回滚功能可让您还原虚拟磁盘的内容，以与快照虚拟磁盘上存在的时 间点映像匹配。

在回滚期间，主机服务器仍可将数据写到基础虚拟磁盘。但是，快照虚拟磁 盘在回滚操作期间设为只读，并在回滚完成后立即变为可用于写入操作。快 照虚拟磁盘在回滚操作期间无法重新启动、删除或禁用。

相关的快照库虚拟磁盘必须有足够的容量以处理回滚操作和主机的写入操作。 快照库虚拟磁盘可能需要最多两倍的基础磁盘大小，外加额外的大概相当于千 分之一 （也就是 0.1%）基础卷容积作为元数据空间。

注：由于主机服务器的写入操作，快照虚拟磁盘中的内容可能自快照创建 以来已发生变化。回滚操作包含在快照创建后对其所作的所有更改。

您可以为回滚操作设置优先级。较高的优先级会给回滚操作分配更多的系 统资源，并将影响系统的整体性能。

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.
