•Before the virtual disk copy begins

•While the virtual disk copy has a status of In Progress

•When you re-create a virtual disk copy

To set copy priority:

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 Change→ Copy Priority.

The Change Copy Priority window is displayed.

4In the Copy priority area, select the appropriate copy priority, depending on your system performance needs.

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.

Stopping a Virtual Disk Copy

You can stop a virtual disk copy operation that has an In Progress status, a Pending status, or a Failed status. Stopping a virtual disk copy that has a Failed status clears the Needs Attention status displayed for the storage array.

Keep these guidelines in mind when you stop a virtual disk copy:

•To use this option, select only one copy pair in the Copy Manager.

•When the virtual disk copy is stopped, all of the mapped hosts have write access to the source virtual disk. If data is written to the source virtual disk, the data on the target virtual disk no longer matches the data on the source virtual disk.

To stop a virtual disk copy, complete the following steps:

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

2Select the copy pair in the table.

3Select Copy→ Stop.

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.
