Disk Group Migration

Disk group migration allows to you export a disk group so that you can import the disk group to a different storage array. You can also export a disk group so that you can store the data offline.

NOTE: During the export process (before the disk group is imported) you lose access to the data on the exported disk group.

NOTE: You must export a disk group before you move the disk group or import the disk group.

Export Disk Group

The export disk group operation prepares the physical disks in the disk group for removal. You can remove the physical disks for offline storage, or you can import the disk group to a different storage array. After you complete the export disk group operation, all of the physical disks are offline. Any associated virtual disks or free capacity nodes are no longer shown in MDSM.

Non-Exportable Components

You must remove or clear any non-exportable settings before you can complete the export disk group procedure. Remove or clear the following settings:

Persistent reservations

Host-to-virtual disk mappings

Virtual disk copy pairs

Snapshot virtual disks and snapshot repository virtual disks

Remote mirror pairs

Mirror repositories

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.
