配置：高级功能——远程复制

远程复制高级功能使得不同地点的两个存储阵列间能够实时复制。使用远 程复制，在一个存储阵列上可以创建多达 16 个辅助的虚拟磁盘对。

一个复制的虚拟磁盘对从两个标准虚拟磁盘创建，它们都是一个存储阵列 上创建的逻辑数据存储结构。一个标准虚拟磁盘只是一个复制对的成员。 一个对包括本地存储阵列的一个主虚拟磁盘和远程存储阵列的一个次虚拟 磁盘。主机写入主虚拟磁盘的数据直接从主存储阵列复制到次虚拟磁盘。 复制过程中不使用任何主机服务器或应用程序资源。数据既可同步也可异 步写入。

如果本地存储阵列出现灾难、通信中断或灾难性故障，远程存储阵列的次 虚拟磁盘可以上升到主虚拟磁盘的位置并承担维持业务运作的责任。

有关创建虚拟磁盘和执行远程复制的详细步骤，请参阅第 165 页上的 “设置与管理远程复制”。

可切换的需要远程复制的主机访问配置

使用远程复制从本地和 / 或远程存储阵列访问主机服务器必须通过支持光 纤通道交换机配置来建立。不支持主机服务器和 Dell PowerVault MD 存储 阵列的直接附加配置。

有关配置交换机环境的详情，请参阅第 164 页上的 “需要的交换机分区 配置”。

激活远程复制

注：如果您订购了远程复制功能，您会收到 Dell PowerVault MD 存储阵列运 输盒中的高级功能激活卡。根据卡上的指示，安装并启用这一功能。

按照高级功能激活卡上的步骤安装远程复制功能后，必须使用安装向导激活。 作为激活的一部分，出现如下操作：

•使用磁盘组或用户指定的存储阵列上的已有容量创建两个复制存储库 虚拟磁盘。

•目前每个 RAID 控制器上使用最多光纤通道主机端口 （端口 3）的所 有主机已注销。

•每个 RAID 存储器上的最多光纤通道主机端口 （端口 3）预留用于复 制数据的传输。

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.
