自我监测分析和报告技术 Smart, 虚拟磁盘和磁盘组, 虚拟磁盘状态

如果磁盘驱动器重建因为源磁盘故障或驱动器过小而失败， MDSM 会报告物理磁盘的故障，即使驱动器上的 LED 状态指示重建已中止（亮起绿

色 3 秒、亮起琥珀色 3 秒，然后熄灭 3 秒）。

自我监测分析和报告技术 (SMART)

SMART 监视所有物理磁盘组件的内部性能，以检测可预测潜在物理磁盘故障的错误。 SMART 使用该信息报告故障是否即将发生，以便在故障发生前能够更换物理磁盘。存储阵列监视所有连接的驱动器，并通知用户物理磁盘何时报告预测故障。

虚拟磁盘和磁盘组

1将物理磁盘组织为磁盘组。

2在这些磁盘组中创建虚拟磁盘。

3提供主机服务器访问权限。

4创建映射以将虚拟磁盘与主机服务器相关联。

注：在映射虚拟磁盘之前，必须创建主机服务器访问权限。

磁盘组总是在存储阵列的未配置的容量中创建。未配置的容量是尚未在存储阵列中分配的可用物理磁盘空间

虚拟磁盘在磁盘组的可用容量中创建。可用容量是磁盘组中尚未分配给虚拟磁盘的空间。

虚拟磁盘状态

存储阵列可识别以下虚拟磁盘状态。

表 4-2. RAID 控制器虚拟磁盘状态

状态	说明

最佳	虚拟磁盘包含的物理磁盘都处于联机状态。
降级	具有冗余RAID 级别的虚拟磁盘包含不可访问的物理磁盘。系统仍然可正
	常工作，但是性能会受到影响，并且额外的磁盘故障可能导致数据丢失。
脱机	具有一个或多个处于不可访问状态（故障、丢失或脱机）的成员磁
	盘的虚拟磁盘。不可再访问虚拟磁盘上的数据。
强制联机	存储阵列会强制处于脱机状态的虚拟磁盘处于Optimal
	（最佳）状态。如果所有成员物理磁盘都不可用，则存储阵列会强制虚拟
	磁盘处于降级状态。仅当有足够数目的物理磁盘可用于支持虚拟磁盘时，
	存储阵列才可以强制虚拟磁盘处于联机状态。

规划：MD3600f 系列存储阵列术语和概念

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.
