未同步的虚拟磁盘

主和次虚拟磁盘之间的通信可以暂停，或成为未同步。如果两个虚拟磁盘 的通信中断：

1复制对的状态更改成 Unsynchronized （未同步）。

2存储阵列显示 Needs Attention （需要注意）状态。

3数据写入到主虚拟磁盘上。

4写入到主虚拟磁盘的请求被记录。

5RAID 控制器模块所有者向发送写请求的主机发送一个 I/O 完成消息。 尽管主机能继续向主虚拟磁盘发送写请求，次虚拟磁盘上没有发生数 据转移。次虚拟磁盘的写入暂停，主虚拟磁盘和次虚拟磁盘之间的通 信有待恢复。

当主虚拟磁盘和次虚拟磁盘之间恢复连接，复制对准备重同步。

注：当主虚拟磁盘和次虚拟磁盘重同步，只有通信中断后主虚拟磁盘上改 变的数据被转移至次虚拟磁盘。

小心：主存储阵列和次存储阵列间重同步启动后，如果通信中断，可能出 现数据损失。除了导致不完整的重同步能使得次存储阵列不可用外，终端的 重同步可能导致两个阵列上的数据都不再完整。

自动重同步虚拟磁盘

当选择自动重同步，拥有主虚拟磁盘的 RAID 控制器模块一旦通信恢复， 就立即自动启动重同步远程复制对上的数据。

注：当选择自动重同步，如果重同步在进行过程中出现中断，可能会出现 数据损失。因为主虚拟磁盘和远程虚拟磁盘间的通信恢复后就自动开始另一 个重同步，数据完整性可能受到影响。

设置了自动重同步，您不能添加一个次虚拟磁盘到写一致性组中。因此， 重同步过程不保持写一致性。写入顺序不一致，除非整个组达到了 Optimal （最佳）状态。

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.
