•The Create Copy Wizard, which assists in creating a virtual disk copy

•The Copy Manager, which monitors virtual disk copies after they have been created

Before you Begin

A virtual disk copy fails all snapshot virtual disks that are associated with the target virtual disk, if any exist. If you select a source virtual disk of a snapshot virtual disk, you must disable all of the snapshot virtual disks that are associated with the source virtual disk before you can select it as a target virtual disk. Otherwise, the source virtual disk cannot be used as a target virtual disk.

A virtual disk copy overwrites data on the target virtual disk and automatically makes the target virtual disk read-only to hosts

If eight virtual disk copies with a status of In Progress exist, any subsequent virtual disk copy has a status of Pending, which stays until one of the eight virtual disk copies completes.

Virtual Disk Copy and Modification Operations

If a modification operation is running on a source virtual disk or a target virtual disk, and the virtual disk copy has a status of In Progress, Pending, or Failed, the virtual disk copy does not take place. If a modification operation is running on a source virtual disk or a target virtual disk after a virtual disk copy has been created, the modification operation must complete before the virtual disk copy can start. If a virtual disk copy has a status of In Progress, any modification operation does not take place.

Create Copy Wizard

The Create Copy Wizard guides you through:

1Selecting a source virtual disk from a list of available virtual disks

2Selecting a target virtual disk from a list of available virtual disks

3Setting the copy priority for the virtual disk copy

When you have completed the wizard dialogs, the virtual disk copy starts, and data is read from the source virtual disk and written to the target virtual disk.

Operation in Progress icons appear on the source virtual disk and the target virtual disk while the virtual disk copy has a status of In Progress or Pending.

MD3200i, MD3220i specifications

The Dell MD3220i and MD3200i are part of Dell's extensive line of modular storage solutions, designed to support organizations in optimizing their data management and scalability requirements. These models offer reliable performance and flexible features, making them suitable for various workloads including virtualization, cloud storage, and disaster recovery.

One of the standout features of the MD3220i and MD3200i is their support for iSCSI storage networking. 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.
