机柜丢失保护, 109 | Dell MD3620F, MD3600f guide

注：对于安全型磁盘组，首选安全型热备用物理磁盘。如果安全型物理磁盘不可用，则可将非安全型物理磁盘用作热备用物理磁盘。要确保该磁盘组保持为安全型，则必须将非安全型热备用物理磁盘更换为安全型物理磁盘。

如果您选择安全型物理磁盘作为非安全型磁盘组的热备用，则会显示一个对话框，提示当前已将安全型物理磁盘用作非安全型磁盘组的热备用。

磁盘组机柜丢失保护的可用性取决于组成磁盘组的物理磁盘的位置。机柜丢失保护可能会因出现故障的物理磁盘和热备用物理磁盘的位置而丧失。要确保机柜丢失保护不受影响，您必须更换出现故障的物理磁盘以启动写回过程。

虚拟磁盘在更换出现故障的物理磁盘时将保持联机状态且可访问，因为热备用物理磁盘会自动替换出现故障的物理磁盘。

机柜丢失保护

机柜丢失保护为磁盘组属性之一。如果单个扩展柜出现通信完全断开的情况，机柜丢失保护可确保磁盘组中虚拟磁盘上数据的可访问性。通信完全断开的示例可能包括：扩展柜断电或两个 RAID 控制器模块都出现故障。

小心：如果磁盘组中的物理磁盘已经出现故障，则机柜丢失保护功能将无法确保可访问性。在此情况下，无法访问扩展柜及磁盘组中后续其他物理磁盘可导致双重物理磁盘故障和丢失数据。

创建磁盘时，如果组成该磁盘组的所有物理磁盘都位于不同的扩展柜中，则可实现机柜丢失保护。此差异取决于 RAID 级别。如果您选择通过自动方法创建磁盘组，该软件将尝试选择提供机柜丢失保护的物理磁盘。如果您选择通过手动方法创建磁盘组，则必须使用中指定的条件。表 9-2

表 9-2.机柜丢失保护条件

	RAID 级别	机柜丢失保护条件

	RAID 级别 5	确保磁盘组中所有的物理磁盘都位于不同扩展柜中。
	或 RAID 级	由于 RAID 级别 5 需要至少 3 个物理磁盘，因此存储阵列拥有的扩
	别 6	由于 RAID 级别 5 需要至少 3 个物理磁盘，因此存储阵列拥有的扩
	别 6	展柜少于 3 个时将无法实现机柜丢失保护。
		展柜少于 3 个时将无法实现机柜丢失保护。
		由于 RAID 级别 6 需要至少 5 个物理磁盘，因此存储阵列拥有的扩
		展柜少于 5 个时将无法实现机柜丢失保护。

109 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.
