注：创建源虚拟磁盘的新快照之前，请停止所有数据访问 (I/O) 操作或暂停向 源虚拟磁盘进行数据传输，以确保捕获准确的源虚拟磁盘快照。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 中移除关联虚拟磁盘的驱动器号或在 Linux 中卸载虚拟驱动 器将有助于确保获得可靠的快照驱动器备份。

创建快照虚拟磁盘之前，主机服务器必须处于正常状态。准备主机服务器：

1停止所有对源的 I/O 活动。

2使用 Windows 系统，将高速缓存刷新到源中。在主机提示符处，键入

SMrepassist -f < 文件名 - 标识符 > 并按下 <Enter>。有关详 情，请参阅第 246 页上的 “SMrepassist 公用程序”。

3在 Windows 中移除源虚拟磁盘的驱动器号或在 Linux 中卸载虚拟驱动 器，将有助于保证稳定地备份用于快照的驱动器。否则，快照操作将 报告已成功完成此任务，但快照数据却无法正确更新。

注：单击 Summary （摘要）选项卡，然后单击 Disk Groups & Virtual Disks （磁盘组与虚拟磁盘）链接，确认虚拟磁盘的状态为 Optimal （最佳）或 Disabled （已禁用）。

4请遵循操作系统的所有附加说明。不遵循这些附加说明可能会导致创 建的快照虚拟磁盘无法使用。

注：如果操作系统需要附加说明，可以在操作系统文档中找到相关说明。

主机服务器准备好后，请参阅第 133 页上的 “使用高级路径创建快照虚 拟磁盘”以使用高级路径创建快照。

如果要定期使用快照 （如用于备份），则使用 Disable Snapshot （禁用快照）

和 Re-create Snapshot （重新创建快照）选项以重新使用快照。禁用和重新创 建快照会将现有的虚拟磁盘到主机的映射保留到快照虚拟磁盘。

使用高级路径创建快照

注：在 Windows 中移除关联虚拟磁盘的驱动器号或在 Linux 中卸载虚拟驱动 器将有助于确保获得可靠的快照驱动器备份。

首先按前述步骤中指定的内容准备主机服务器后，完成以下步骤以使用高 级路径创建虚拟磁盘快照：

1停止主机应用程序对源虚拟磁盘的访问，然后卸载源虚拟磁盘。

2在 AMW 中，选择 Logical （逻辑）选项卡并选择有效的源虚拟磁盘。

配置：高级功能—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.
