设置写模式

存储阵列的次主机端口为复制虚拟磁盘对的主虚拟磁盘和次虚拟磁盘之间 进行数据同步预留。您可以设置远程复制同步或异步写。

•在同步模式，数据成功复制到次存储阵列后，主虚拟磁盘上的 RAID 控制器模块将 I/O 完成信息回送至主机存储阵列。同步模式在发生灾 难时最有可能从次存储阵列中恢复全部数据，因此是首选的操作模式。 但是，如果涉及远距离数据传输，同步复制会降低主机的 I/O 性能。

•在异步模式，数据成功复制到次存储阵列后，主虚拟磁盘上的 RAID 控制器模块将 I/O 完成信息返回发送至主机存储阵列。异步模式提供 更快的主机 I/O 性能；但它不能保证数据成功写入到次虚拟磁盘中， 或次虚拟磁盘上的写入请求顺序与初始化时不一致。在异步模式，您 也可以指定是否要使用写一致性组选项。写一致性组确保次虚拟磁盘 接收到的写入请求顺序与主虚拟磁盘的 RAID 控制器模块初始化的顺 序一致。次虚拟磁盘也可添加到写一致性组中。

设置远程复制的写模式：

1在 Set Write Mode (Create Remote Replication)（设置写模式（创建远 程复制））向导中，选择 Synchronous （同步）或 Asynchronous

（异步）模式。

2如果选择异步模式，选择是否使用 Add to write consistency group

（添加到写一致性组）选项。

3单击 “Next”（下一步）。

设置同步优先项和同步方法

您可以设置分配资源的优先性，以同步远程复制。

•高同步优先项为该进程分配更多的资源，可能会降低 I/O 性能。

•低同步优先项为该进程分配更少的资源，对正常的 I/O 性能影响更小。

您选择的初始同步优先项和同步方法以后可以改变。有关重同步远程复制 的虚拟磁盘的更多详细信息，请转至第 175 页上的 “重同步虚拟磁盘”。

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.
