配置：磁盘组和虚拟磁盘

创建磁盘组和虚拟磁盘

磁盘组在存储阵列未配置的容量中创建，而虚拟磁盘在磁盘组的可用容量 中创建。磁盘组中支持的最大物理磁盘数量为 30。连接至存储阵列的主 机从虚拟磁盘读取数据，并向虚拟磁盘写入数据。

注：在创建虚拟磁盘之前，必须先将物理磁盘组织为磁盘组并配置主机访 问权限。然后在磁盘组中创建虚拟磁盘。

要创建虚拟磁盘，请使用以下方法之一：

•从未配置的容量中创建新磁盘组。先为磁盘组定义 RAID 级别和可用容 量 （可用存储空间），然后为新磁盘组中的第一个虚拟磁盘定义参数。

•在现有磁盘组的可用容量中创建新的虚拟磁盘。只需指定新虚拟磁盘 的参数。

磁盘组具有一组在创建磁盘组时所配置的可用容量。您可以使用该可用容 量将磁盘组细分为一个或多个虚拟磁盘。

使用以下方法可创建磁盘组和虚拟磁盘：

•自动配置—提供最快速的方法，但配置选项有限。

•手动配置—提供更多配置选项。

创建虚拟磁盘时，请考虑虚拟磁盘的用途，并根据其用途选择相应的容 量。例如，如果磁盘组具有一个用于存储多媒体文件 （通常会很大）的 虚拟磁盘和另一个用于存储文本文件 （通常会较小）的虚拟磁盘，则多 媒体文件虚拟磁盘会比文本文件虚拟磁盘需要更多的容量。

必须根据磁盘组相关的任务及子任务来组织磁盘组。例如：如果为会计部 门创建磁盘组，则可创建适合部门内不同类型会计交易的虚拟磁盘：应收 帐款 (AR)、应付帐款 (AP)、内部结算等。在此情况下， AR 和 AP 虚拟磁 盘可能比内部开单虚拟磁盘需要更多的容量。

注：在 Linux 中，删除虚拟磁盘后必须重新引导主机，才能重设 /dev 条目。

注：在使用虚拟磁盘之前，必须通过主机系统注册该磁盘。请参阅第 110 页 上的 “主机到虚拟磁盘的映射”。

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.
