执行快照回滚的规则和原则

以下规则和原则可用于执行快照回滚：

•将基础虚拟磁盘回滚到快照虚拟磁盘不影响快照虚拟磁盘的内容。

•一次只能执行一个快照回滚操作。

•基础虚拟磁盘正在进行回滚时，您将无法从该基础虚拟磁盘创建新的 快照虚拟磁盘。

•正在进行以下任何操作时，将无法启动快照回滚：

–虚拟磁盘容量扩充

–虚拟磁盘扩展 (VDE)

–RAID 级别迁移

–分段大小迁移

–虚拟磁盘备份

–角色反转 （在远程复制中）

•如果基础虚拟磁盘在远程复制中是次级虚拟磁盘，您将无法执行快照 回滚。

•如果相关快照库虚拟磁盘中使用的任何容量包含不可读扇区，快照回 滚将失败。

如果回滚期间发生错误，操作将暂停，并且基础虚拟磁盘和快照虚拟磁盘显

示 Needs Attention （需要注意）图标。 RAID 控制器模块还会将事件记录到 主要事件日志 (MEL)。按照 Recovery Guru 步骤更正错误并重复回滚操作。

警告：数据丢失风险：如果您取消正在进行中的快照回滚，基础虚拟磁盘 可能保持为不可用状态，并且快照虚拟磁盘在 MD 存储管理软件中显示为故 障。因此，除非存在恢复基础虚拟磁盘内容的可靠恢复选项，否则不要取消 快照回滚。

命令行选项

作为其他选择，您也可以使用命令行界面 (CLI) 启动、取消、恢复或修改 快照回滚的优先级。有关详情，请参阅 命令行界面指南。

防止失败的快照回滚

为保护基础虚拟磁盘数据，建议您在回滚操作开始前从基础虚拟磁盘创建 新的快照虚拟磁盘。如果快照回滚失败，请使用此新快照虚拟磁盘恢复您 的基础虚拟磁盘。

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.
