主机服务器到虚拟磁盘映射

与存储阵列连接的主机服务器通过其主机端口访问存储阵列上的各个虚拟 磁盘。可以定义单个主机服务器的特定虚拟磁盘到 LUN 的映射。此外， 主机服务器可以属于共享一个或多个虚拟磁盘的访问权限的主机组。

可手动配置主机服务器到虚拟磁盘的映射。配置主机服务器到虚拟磁盘的 映射时，请注意以下原则：

•可为存储阵列中的每个虚拟磁盘定义一个主机服务器到虚拟磁盘的映射。

•主机服务器到虚拟磁盘的映射在存储阵列中的 RAID 控制器模块之间 共享。

•主机组或主机服务器必须使用唯一的 LUN 访问虚拟磁盘。

•并非每个操作系统都具有相同数量的可用 LUN。

主机类型

主机服务器是访问存储阵列的服务器。主机服务器映射到虚拟磁盘。其具 有以下属性：

•主机名—用于唯一标识主机服务器的名称。

•主机组 （只用于群集解决方案中）—两个或更多主机服务器关联到一 起以共享对同一虚拟磁盘的访问权限。

该主机组是可在 MDSM 中创建的逻辑实体。主机组中的所有主机服务 器都必须运行相同的操作系统。

•主机类型—主机服务器上运行的操作系统。

快照虚拟磁盘

快照是虚拟磁盘的时间点映像。在创建快照时，快照会提供虚拟磁盘的映像。 可创建快照以使应用程序 （例如备份应用程序）可以在源虚拟磁盘保持联机 和用户可访问的状态时访问快照并读取数据。如果备份完成，则不再需要快照 虚拟磁盘。每个虚拟磁盘最多可以创建四个快照。

快照用于将拍摄快照后有所更改的文件恢复至之前的版本。使用写入时复 制算法来实施快照，在发生错误后，该算法可即刻制作数据的备份。而且 会在修改虚拟磁盘上的数据之前将其复制到快照库。可以立即创建快照， 或计划创建，并且比完整的物理备份过程开销更少。

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.
