•远程复制高级功能激活时，每个 RAID 存储器上的最多光纤通道主机 端口 （端口 3）不可指示主机访问。拒绝任何试图与该端口进行主机 通讯。

•预留复制的光纤通道端口间的通讯需要此构造中已经建立光纤通道交 换机分区，请参阅第 164 页上的 “需要的交换机分区配置”。

•建立虚拟磁盘复制对之前，必须在每个参与复制的存储阵列上激活远 程复制高级功能。

复制存储库虚拟磁盘

在存储阵列上使用远程复制高级功能需要存储阵列的一个磁盘组上创建两 个复制存储库虚拟磁盘。 RAID 控制器模块在这些虚拟磁盘上存储复制信 息，包括可用于从 RAID 控制器模块重置和偶然存储阵列关闭中恢复的不 完全远程写入信息。

有关复制存储库虚拟磁盘的其他信息包括：

•具体说明复制存储库虚拟磁盘从磁盘组的未配置可用容量中创建，或 从存储阵列上的未配置可用容量中创建新磁盘组和它的成员复制存储 库虚拟磁盘。

注：包含复制存储库虚拟磁盘的磁盘组在不禁用远程复制高级功能的 情况下不能删除。

•复制存储库虚拟磁盘的默认名称是复制存储库 1 和 复制存储库 2。这些 名称不可更改。

•激活过程创建相同容量的复制存储库虚拟磁盘。在双重 RAID 控制器 模块存储阵列中，每个复制存储库虚拟磁盘的默认容量是每控制器 128 MB （RAID 组中一共需要 256 MB）。默认容量不可修改。

复制存储库虚拟磁盘的 RAID 级别

如果复制存储库虚拟磁盘创建于存储阵列上的未配置可用空间，您可以选 择的磁盘组 RAID 级别有 RAID 1/10、 RAID 5 或 RAID 6。但是，如果复制 存储库虚拟磁盘创建与已有的磁盘组，则用户不可配置 RAID 级别。

主和次虚拟磁盘对

激活远程复制，创建 FC 构造的配置、每个虚拟磁盘复制对后，可以建立 多达 16 个复制虚拟磁盘对。每个对包括容量相同的主 （在线）虚拟磁盘 和次 （离线）虚拟磁盘。运行过程中，主次角色可以互换，以检测复制 的数据集而不破坏关联。删除关联可创建独立的副本，此时两个虚拟磁盘 都可与它们的配置主机在线连接。

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.
