Dell MD3220i, MD3200i owner manual Removing Copy Pairs, 174

Page 174

NOTE: There are five copy priority rates available: lowest, low, medium, high, and highest. If the copy priority is set at the lowest rate, I/O activity is prioritized, and the virtual disk copy takes longer. If the copy priority is set to the highest priority rate, the virtual disk copy is prioritized, but I/O activity for the storage array might be affected.

Removing Copy Pairs

You can remove one or more virtual disk copies by using the Copy Manager. Any virtual disk copy-related information for the source virtual disk and the target virtual disk is removed from the Virtual Disk Properties dialog and the Storage Array Profile dialogs. When you remove a virtual disk copy from the storage array, the Read-Only attribute for the target virtual disk is also removed. After the virtual disk copy is removed from the Copy Manager, you can either select the target virtual disk as a source virtual disk or the target virtual disk for a new virtual disk copy.

If you remove a virtual disk copy, the source virtual disk and the target virtual disk no longer appear in the Copy Manager.

Keep these guidelines in mind when you remove copy pairs:

•Removing copy pairs does not delete the data on the source virtual disk or target virtual disk.

•If the virtual disk copy has a status of In Progress, you must stop the virtual disk copy before you can remove the copy pair.

To remove copy pairs:

1In the AMW, select Virtual Disk→ Copy→ Copy Manager. The Copy Manager window is displayed.

2In the table, select one or more copy pairs.

3Select Copy→ Remove Copy Pairs. The Remove Copy Pairs dialog appears.

4Click Yes.

By utilizing the Internet Small Computer Systems Interface (iSCSI) protocol, these systems provide organizations with a cost-effective way to connect their storage over existing network infrastructure, enabling efficient data transfers and management.

Both models are equipped with dual controllers that ensure high availability and failover capabilities, which are crucial for meeting uptime requirements in mission-critical environments. The dual controllers also facilitate load balancing and increase overall system performance, as they allow multiple paths to the storage, enhancing I/O performance.

Scalability is another key characteristic of the MD3220i and MD3200i. These storage arrays can be expanded to meet growing storage demands, supporting up to 240TB of raw capacity with up to 16 additional expansion enclosures. This flexibility allows organizations to start with a smaller configuration and grow their storage capabilities without a complete overhaul of the existing infrastructure.

The units also support multiple disk types, including traditional spinning disks, solid-state drives (SSDs), and a combination of both. This versatility enables users to tailor storage configurations to their specific performance and budgetary needs. Furthermore, the systems feature advanced data management technologies such as snapshots and remote replication, providing essential tools for data protection.

With their ease of management, the MD3220i and MD3200i are designed for straightforward configuration and operation. The intuitive management interfaces allow IT professionals to monitor performance, configure storage, and manage data effectively, ensuring businesses can maintain optimal system availability.

In summary, the Dell MD3220i and MD3200i are robust, scalable, and versatile storage solutions that cater to diverse organizational needs. Their integrated technologies, such as iSCSI support, dual controller architecture, and advanced data management features, make them an ideal choice for modern data centers looking to enhance storage capabilities while ensuring reliability and performance.
