规划：MD3600f 系列存储阵列术 语和概念

本章介绍用于配置和操作 MD3600f 系列存储阵列的术语和概念。

物理磁盘、虚拟磁盘和磁盘组

存储阵列中的物理磁盘为数据提供物理存储容量。在可以开始将数据写入 存储阵列之前，必须将物理存储容量配置为逻辑组件，这些逻辑组件称为 磁盘组和虚拟磁盘。

磁盘组是一组物理磁盘，可在其上创建多个虚拟磁盘。对于 RAID 0、 RAID 1 和 RAID 10，磁盘组中支持的最大物理磁盘数量为 120 个磁盘 （或在高级功能激活时为 192 个磁盘），对于 RAID 5 和 RAID 6 则为 30 个驱动器。可从存储阵列上的未配置容量创建磁盘组。

虚拟磁盘是磁盘组中的一个分区，该分区由磁盘组中的物理磁盘的连续数 据段组成。虚拟磁盘则由来自磁盘组中的所有物理磁盘的数据段组成。虚 拟磁盘和磁盘组根据整理数据的计划来设置。例如：可将一个虚拟磁盘用 于存储库存信息，将第二个虚拟磁盘用于存储财务和税务信息，等等。

磁盘组中的所有虚拟磁盘都支持相同的 RAID 级别。存储阵列最多支持

255个可分配至主机服务器的虚拟磁盘 （每个大小至少为 10 MB）。每个 虚拟磁盘均分配有可由主机操作系统识别的逻辑单元号码 (LUN)。

物理磁盘

存储阵列中仅支持 Dell 支持的 6.0-Gbps SAS 物理磁盘。如果存储阵列检 测到不支持的物理磁盘，就会将磁盘标记为 “不支持”，并且无法对物理 磁盘进行任何操作。

注：MD3600f 系列存储阵列必须至少包含两个物理磁盘才能正常工作。这是 必要的，因为物理磁盘用于存储配置信息。

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.
