注：磁盘组可能不会使用新 I/O 路径，直到重新配置多路径驱动程序并识别 出新路径。此操作通常不会超过 5 分钟。

更改磁盘组的 RAID 级别

更改磁盘组的 RAID 级别会更改组成该磁盘组的每个虚拟磁盘的 RAID 级 别。在此操作期间，性能可能会略受影响。

更改磁盘组 RAID 级别的原则：

•此操作一旦开始便无法取消。

•磁盘组必须处于 Optimal （最佳）状态，才能执行此 操作。

•在此操作期间，数据仍然可用。

•如果磁盘组中没有足够的容量转换为新的 RAID 级别，则会显示一条

错误信息，并暂停该操作。如果您有未分配的物理磁盘，请使用 Disk Group （磁盘组） → Add Free Capacity (Physical Disks) （添加可用容 量 [ 物理磁盘 ]）选项将附加容量添加到该磁盘组。然后重试该操作。

更改磁盘组的 RAID 级别：

1在 AMW 中，选择 Logical （逻辑）选项卡并选择一个磁盘组。

2选择 Disk Group （磁盘组） → Change （更改） → RAID Level

（RAID 级别）。

3选择相应的 RAID 级别，然后单击 Yes （是）以确认选择。

此时将启动 RAID 级别操作。

使用 Linux DMMP 删除主机到虚拟磁盘的映射

要使用 Linux DMMP 删除主机到虚拟磁盘的映射，请执行以下步骤：

1卸载包含虚拟磁盘的文件系统：

#umount filesystemDirectory

2运行以下命令以显示多路径拓扑：

#multipath -ll

记录您要从映射中删除的虚拟磁盘。例如：可能显示以下信息：

mpath6 (3600a0b80000fb6e50000000e487b02f5) dm-10 DELL, MD32xx

[size=1.6T][features=3 queue_if_no_path pg_init_retries 50][hwhandler=1 rdac]

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.
