RAID 1

RAID 1 使用磁盘镜像技术，数据在写入到一个物理磁盘的同时也写入到另一个物理磁盘中。该 RAID 级别提供快速的性能和最佳的数据可用性，但是磁盘开销也最高。建议将 RAID 1 用于小型数据库或不需要较大容量的其它应用程序。 RAID 1 提供完全数据冗余。例如：会计、薪酬或财务应用程序。

RAID 5

RAID 5 在所有物理磁盘中使用奇偶校验和分拆数据（分布式奇偶校验）以提供高数据吞吐量和数据冗余，这尤其适用于小型随机存取。这是多用

途 RAID 级别，适合多用户环境，其中典型 I/O 数量较小且大部分是读取操作，例如：文件、应用程序、数据库、 Web、电子邮件、新闻和内部网服务器。

RAID 6

RAID 6 与 RAID 5 相似，但是可提供额外的奇偶校验磁盘以实现更佳的冗余。这是用途最广的 RAID 级别，适合多用户环境，其中典型 I/O 数量较小且大部分是读取动作。如果使用了较大的物理磁盘或者在磁盘组中使用了大量物理磁盘，则建议使用 RAID 6。

RAID 10

RAID 10 是 RAID 1 和 RAID 0 的组合，使用跨镜像磁盘范围的磁盘分拆技术。它能提供高数据吞吐和完整的数据冗余。使用偶数数目的物理磁盘（四个或更多）创建 RAID 级别 10 磁盘组和 / 或虚拟磁盘。因为 RAID 级

别 1 和 10 使用磁盘镜像，所以物理磁盘有一半的容量会用于镜像。同时将另一半物理磁盘容量用于实际存储。在使用四个或更多的物理磁盘时，如果选择了 RAID 级别 1，则会自动使用 RAID 10。 RAID 10 很适合中型数据库，或者任何需要高性能和容错能力以及适度到中等容量的环境。

磁盘分拆可实现在多个物理磁盘上写入数据。由于会同时访问分拆的磁盘，因此磁盘分拆可增强性能。

分段大小或磁条元素大小指定写入单个磁盘的磁条中的数据大小。 MD3600f 系列阵列支持大小为 8 KB、 16 KB、 32 KB、 64 KB、 128 KB、 256 KB 和 512 KB 的磁条元素。默认的磁条元素大小为 128 KB。

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.
