配置:高级功能虚拟磁盘备份

注:虚拟磁盘副本将覆盖目标虚拟磁盘上的数据。开始虚拟磁盘备份之前,

请确保您不再需要目标虚拟磁盘上的数据或将这些数据备份。

注:如果您已订购此功能,则会收到 Dell PowerVault MD 存储阵列附带的高 级功能激活卡。请按照此卡中的说明获取密钥文件并启用该功能。

注:创建虚拟磁盘备份的首选方法是从快照虚拟磁盘进行备份。此方法可 使快照操作中所用的原始虚拟磁盘在快照用作虚拟磁盘备份操作源时,保持 可完全用于进行读 / 写操作。

创建虚拟磁盘备份时,会在同一存储阵列上创建具有源虚拟磁盘和目标虚 拟磁盘的备份对。

源虚拟磁盘是包含您要复制的数据的虚拟磁盘。源虚拟磁盘接受主机 I/O 读取活动并存储数据直至数据复制到目标虚拟磁盘。源虚拟磁盘可以是标 准虚拟磁盘、快照虚拟磁盘或快照虚拟磁盘的源虚拟磁盘。开始虚拟磁盘 备份后,所有数据将复制到目标虚拟磁盘,并且源虚拟磁盘的权限将设置 为只读直至虚拟磁盘备份完成。

目标虚拟磁盘是您将数据从源虚拟磁盘复制到的虚拟磁盘。目标虚拟磁盘 可以是标准虚拟磁盘,也可以是出现故障或已禁用的快照虚拟磁盘的源虚 拟磁盘。

虚拟磁盘备份完成后,源虚拟磁盘将可接受主机应用程序的写入请求。为 防止出现错误信息,请勿尝试在进行虚拟磁盘备份时访问参与虚拟磁盘备 份的源虚拟磁盘。

使用虚拟磁盘备份的原因包括以下各项:

复制数据以改进访问当虚拟磁盘的存储要求更改时,可以使用虚拟 磁盘备份将数据复制到使用同一存储阵列内具有较大容量驱动器的磁 盘组中的虚拟磁盘。复制数据以获得较大的访问容量使您可以将数据 移至较大容量的物理磁盘 (例如, 61 GB 146 GB)。

将快照虚拟磁盘数据恢复至源虚拟磁盘虚拟磁盘备份功能使您可以 首先从快照虚拟磁盘恢复数据,然后将数据从快照虚拟磁盘复制到原 始的源虚拟磁盘。

创建备份副本 虚拟磁盘备份功能使您可以通过将数据从一个虚拟磁 盘 (源虚拟磁盘)复制到同一存储阵列中的其它虚拟磁盘 (目标虚拟 磁盘)来创建虚拟磁盘的备份,从而尽量减少源虚拟磁盘不可用于主

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.
