制定快照虚拟磁盘计划

创建快照虚拟磁盘时，您可以选择是否立即创建快照，或是根据您确定的 计划创建。此计划可以是一次性快照创建或以定期出现间隔进行的持续快 照创建。如果未指定计划，快照虚拟磁盘创建会在执行命令时立即进行。

计划可以在首次创建快照虚拟磁盘时指定，或者可以随时添加到现有的快 照虚拟磁盘。每个快照虚拟磁盘支持一个计划。

制定快照虚拟磁盘计划的一般原因

制定可在不同数据存储环境中用作多种用途的快照虚拟磁盘计划。最常用 的快照计划程序有：

•数据备份

•从数据丢失事件中快速恢复

计划的数据备份可以定期的、自动的对数据丢失进行防护。例如：如果应 用程序在存储阵列的两个虚拟磁盘中存储业务攸关的数据，您可以选择每 天执行自动备份。要实施此备份，请选择第一个虚拟磁盘并创建每天运行 一次的备份计划，从星期一到星期五，时间在工作日结束时间到晚上 11 点之间。不要选择结束日期。对第二个虚拟磁盘应用同一计划，然后将两 个快照虚拟磁盘映射到您的备份主机服务器，并执行定期备份过程。切记 在下一个计划的快照开始前取消两个之前生成的快照虚拟磁盘的映射。如 果未取消快照虚拟磁盘映射，存储阵列将不执行下一个计划的快照操作以 便避免数据损坏。

计划的快照在数据丢失事件中也很重要。例如：如果您在每天工作结束时 备份数据，并在上午 8 点到下午 5 点间每小时保留一次快照，则数据可在 小于一小时的窗口期内从快照恢复。要完成此类快速恢复，请创建包含开 始时间是早上 8 点，结束时间是下午 5 点的计划，然后在星期一到星期五 每天选择 10 个快照，且没有结束日期。

创建快照计划的原则

某些原则在创建快照虚拟磁盘计划时适用：

•计划的虚拟磁盘快照操作在以下情况下不发生：

–快照虚拟磁盘被映射

–存储阵列脱机或关机

–快照虚拟磁盘在虚拟磁盘备份操作期间用作源虚拟磁盘

–备份操作挂起或正在进行

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.
