RAID 控制器模块的故障排除

状态

某些事件会导致 RAID 控制器模块发生故障和 / 或关闭。不可恢复的 ECC 内存或 PCI 错误，或是处于严重的物理状态时可能导致死锁。如果 RAID 存储阵列配置了冗余存取和高速缓存镜像，则无故障的控制器可以正常恢 复而不丢失数据或关闭。

以下章节将详细介绍典型的控制器故障。

无效存储阵列

RAID 控制器模块仅在 Dell 支持的存储阵列中受到支持。安装到存储阵列 中后，控制器将执行一系列验证检查。 RAID 控制器模块完成这些初始化 测试且控制器引导成功后，阵列状态 LED 将持续亮起琥珀色。如果 RAID 控制器模块检测到 Dell 不支持的存储阵列，则控制器将中止启动。 RAID 控制器模块不会产生任何事件以警告您存在无效阵列，但阵列状态 LED 将闪烁琥珀色以表示故障状态。

有关 LED 及其含义的详细信息，请参阅第 26 页上的 “背面板部件和指 示灯”。

ECC 错误

无论 RAID 控制器模块是否拥有冗余配置， RAID 控制器固件都可检测到 ECC 错误并从单位 ECC 错误中恢复。带冗余控制器的存储阵列还可从多

位 ECC 错误中恢复，因为在必要时，对等 RAID 控制器模块可以接管故 障模块的工作。

如果发生多达 10 个单位错误或最多 3 个多位错误，则 RAID 控制器模块 会执行故障转移。

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.
