带有远程复制的虚拟磁盘备份

虚拟磁盘备份高级功能将源虚拟磁盘上的数据复制到相同存储阵列上的目 标虚拟磁盘。

远程复制中的主虚拟磁盘在虚拟磁盘备份中可以是源虚拟磁盘也可以是目 标虚拟磁盘。

您可以在复制对的主虚拟磁盘上创建虚拟磁盘备份，但是不可以在复制对 的次虚拟磁盘上创建虚拟磁盘备份。然而，您可以使用以下两种方式之一 备份次虚拟磁盘：

•将次虚拟磁盘升级至主虚拟磁盘。

小心：如果在虚拟磁盘备份运行时出现主 / 次角色反转，虚拟磁盘备份会发 生故障，不能再重启。

•为次虚拟磁盘创建快照虚拟磁盘，然后执行快照虚拟磁盘的虚拟磁盘 备份。

带有远程复制的虚拟磁盘扩展

虚拟磁盘扩展 (VDE) 增加了已有虚拟磁盘的容量。增加的容量可通过以 下可用容量之一实现：

•标准虚拟磁盘的磁盘组，或

•快照存储库虚拟磁盘。

执行 VDE 操作不会中断访问磁盘组、虚拟磁盘或物理磁盘上的数据。

VDE 操作可以在复制对的主虚拟磁盘或次虚拟磁盘上执行。它不能在复 制存储库虚拟磁盘上执行。虚拟磁盘在进行扩展时不能执行其他操作 （除了正常的磁盘 I/O）。

注：要执行 VDE 操作，远程复制必须处于 Optimal （最佳）状态。逻辑视图 中的属性面板显示了虚拟磁盘的状态。

需要的交换机分区配置

注：存储阵列支持有限的光纤交换机集。有关支持的交换机和它们需要的 驱动器、 BIOS 和固件级别的完整一览表，请参阅配置 Dell MD3600f 系列存储 阵列的光纤通道。

由于主机级别的潜在限制，远程复制配置必须包含光纤通道交换机。必须 为光纤通道交换机分区，这样一个主机适配器只访问存储阵列中的一个 RAID 控制器模块。另外，所有的分区配置必须为预留远程复制功能的端 口指定独立分区。

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.
