手动重同步虚拟磁盘

当选择手动重同步，您必须在主和远程虚拟磁盘间的通信恢复后，手动重 同步和继续远程复制上的数据转移。手动重同步是所有远程同步的推荐设 置，原因如下：

•您能决定重同步启动的时间，从而可以更好地管理和 / 或降低对 I/O 性 能的影响。

•在灾难恢复情况下，手动重同步最有可能检索到有效数据。

•当次虚拟磁盘在一些一致性组中时，手动重同步保持了写入顺序。

反转主和次虚拟磁盘间的角色

反转虚拟磁盘间的角色是将次虚拟磁盘升级到主虚拟磁盘的角色，将主虚 拟磁盘降级到次虚拟磁盘的角色。如果远程虚拟磁盘的主虚拟磁盘复制出 现故障，您可以反转主虚拟磁盘和次虚拟磁盘的角色，将数据转移回到已 恢复的虚拟磁盘。

小心：当一虚拟磁盘备份正在进行时，如果您反转次虚拟磁盘和主虚拟磁 盘间的角色，会出现潜在的数据访问损失。角色反转可能成功，但虚拟磁盘 发生故障，不能再重启。

•您不能在一虚拟磁盘远程复制的次虚拟磁盘上执行虚拟磁盘备份。要 创建次虚拟磁盘的虚拟磁盘备份，您必须反转次虚拟磁盘和主虚拟磁 盘的角色，然后再新的主虚拟磁盘上执行虚拟磁盘备份。

•当一个虚拟磁盘远程复制正在同步时，您不能在主或次虚拟磁盘上执 行虚拟磁盘备份。

•如果您在容量比主虚拟磁盘少的次虚拟磁盘间反转角色，角色可以成 功反转，但新的主虚拟磁盘的可用容量就与次虚拟磁盘的总容量相当。

升级次虚拟磁盘或降级主虚拟磁盘

要将次虚拟磁盘升级到主虚拟磁盘的角色，或将主虚拟磁盘降级到次虚拟 磁盘的角色：

1在包含您正在更改的虚拟磁盘的存储阵列的 AMW 中，单击 Logical （逻辑）选项卡。

2右键单击你正在更改的虚拟磁盘。

•如果您正在将次虚拟磁盘升级到主虚拟磁盘的角色，选择 Change

（更改） → Role （角色）至 Primary （主）。显示 Change to Primary （更改至主）消息。单击 Yes （是）反转主和次虚拟磁盘 的角色。

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.
