系统密码重设

如果不慎遗忘了存储阵列系统密码，可以进行重设。要重设密码，可按住密码重设开关 5 秒。随即删除密码。请参阅图 3-1以定位密码重设开关。

RAID 控制器模块可用于更改密码。有关设置密码的详情，请参阅第 66 页上的 “设置密码”。

注：可使用细小物件，例如笔尖来触碰重设开关。

高速缓存的功能和特点

高速缓存镜像

高速缓存镜像功能可将已接收的主机写入数据从主控制器复制到辅助控制器。该操作可确保成功完成状态返回主机之前，将主机写入数据安全地映射到辅助控制器。如果控制器出现故障，其余控制器则会安全地保留所有映射数据。高速缓存默认启用。

回写式高速缓存

在回写式高速缓存中，写入操作会导致高速缓存一旦收到要写入的数据，便向主机操作系统发送完成信号。目标物理磁盘将在更适当的时间接收数据以提高控制器性能。当您采用已启用回写式高速缓存的双活动控制器配置时，在将完成状态发送给主机启动程序之前，写入数据始终会映射至第二控制器的高速缓存。回写式高速缓存默认启用，除非禁用了高速缓存镜像。

直写式高速缓存

在直写式高速缓存中，在将完成状态返回主机操作系统之前，会将数据写入物理磁盘。由于直写式高速缓存在发生电源故障时不易导致数据丢失，因此一般认为它比回写式高速缓存更为可靠。如果禁用高速缓存镜像或缺少电池或存在故障， RAID 控制器便会自动切换至直写式。

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.
