计划在指定时间创建快照虚拟磁盘或根据定期发生的时间间隔创建。 如果未指定计划,则快照操作会立即开始。此参数也可用于将计划应 用于现有的快照虚拟磁盘。

准备主机服务器以使用高级路径创建快照

注:Microsoft Windows 群集配置中使用快照虚拟磁盘高级功能之前,首 先必须将快照虚拟磁盘映射到拥有源虚拟磁盘的群集节点。这样可确保群集 节点能够正确地识别快照虚拟磁盘。

注:如果在完成快照启用过程之前将快照虚拟磁盘映射到未拥有源虚拟磁 盘的节点,则可能导致操作系统不能正确地识别快照虚拟磁盘。这进而可能 导致源虚拟磁盘上的数据丢失或无法访问快照。

注:有关将快照虚拟磁盘映射至次级节点的详细信息,请参阅 support.dell.com/manuals 上的带 Microsoft Windows Server 故障转移集群的 Dell PowerVault MD3200 MD3220 存储阵列。

快照库虚拟磁盘的目标取决于磁盘组中的可用容量。快照库虚拟磁盘需要 最小 8 MB 的可用容量。如果源虚拟磁盘的磁盘组具有所需的可用空间量, 则您可以选择首选的创建路径 (简单或高级)。

如果源虚拟磁盘的磁盘组中没有 8 MB 的可用容量,则 Create Snapshot Virtual Disks (创建快照虚拟磁盘)功能将默认采用高级路径 (请参阅)。

133 页上的 使用高级路径创建快照虚拟磁盘在高级路径选项中,您 可以选择将快照库虚拟磁盘放在其它磁盘组中,或使用存储阵列上未配置 的容量来创建一个新的磁盘组。

注:您可以在源磁盘组和其它磁盘组上同时创建源虚拟磁盘的并发快照。

在创建 Snapshot Virtual Disk (快照虚拟磁盘)前,请牢记以下指示:

以下类型的虚拟磁盘为无效的源虚拟磁盘:

快照存储库虚拟磁盘。

快照虚拟磁盘。

复制存储库虚拟磁盘。

参与制作虚拟磁盘备份的目标虚拟磁盘。

注:虚拟磁盘备份是一项高级功能。

如果虚拟磁盘包含无法读取的扇区,则无法创建此虚拟磁盘的快照。

必须满足主机操作系统的要求才能创建快照虚拟磁盘。如果未能满足 主机操作系统的要求,将导致虚拟磁盘备份中的源虚拟磁盘或目标虚 拟磁盘的快照出现偏差。

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.
