虚拟磁盘 RAID 级别迁移

分段大小迁移

虚拟磁盘容量扩充

磁盘组扩充

磁盘组碎片整理

如果冗余 RAID 控制器模块在进行现有磁盘组进程时失败,则故障的控制 器上的进程会转移至对等控制器。如果对等控制器上已存在一个活动的磁 盘组进程,则会将转移的进程置于暂挂状态。当对等控制器上的活动进程 完成或停止之后,会恢复暂挂的进程。

注:如果尝试在没有活动进程的控制器上启动磁盘组进程,而且磁盘组中 的第一个虚拟磁盘由其他控制器拥有且其他控制器上存在活动的进程,则启 动尝试会失败。

RAID 后台操作优先级

存储阵列对以下 RAID 操作支持常用的可配置优先级:

后台初始化

重建

回写

虚拟磁盘容量扩充

RAID 级别迁移

分段大小迁移

磁盘组扩充

磁盘组碎片整理

这些操作中的每个操作都可更改其优先级,以满足要执行操作的环境的性 能要求。

注:设置高优先级会影响存储阵列性能。不建议在最高级别设置优先级。还 必须依据对于主机服务器访问的影响和完成操作的时间来评估优先级。例如: 对已降级的虚拟磁盘的重建时间越长,次级磁盘出现故障的风险就越大。

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.
