其中

mpathb 是由 Device Mapper 创建的虚拟设备的名称。它位于 /dev/mapper 目录中。

DELL 是设备供应商

MD36xxf 是设备型号

Sdx 是设备所属控制器的物理路径

Sdcl 是设备的非所属控制器的物理路径

在多路径设备节点上新建 fdisk 分区

fdisk 命令可为特定文件系统创建分区空间，这些文件系统位于提供给 Device Mapper 的新扫描到的虚拟磁盘和新映射的虚拟磁盘上。

例如，使用以下命令用多路径设备节点 /dev/mapper/mpath<x> 创建分区， 其中 mpath<x> 是要在其上创建分区的多路径设备节点：

# fdisk /dev/mapper/mpath<x>

注：<x> 值是取决于字母数字操作系统的格式。使用先前运行的多路径命 令，可看到映射的虚拟磁盘的相应值。有关 fdisk 用法的其他信息，请参阅 操作系统文档。

向 Device Mapper 添加新分区

kpartx 命令可将 fdisk 新创建的分区添加至 Device Mapper 的可用分区 列表。请参阅以下示例，其中 mpath<x> 是要在其上创建分区的设备节 点。

# kpartx – a /dev/mapper/mpath<x>

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.
