Re-creating Snapshot Virtual Disks

You can re-create a snapshot virtual disk that you have previously disabled.

CAUTION: Possible loss of data redundancy – If the snapshot virtual disk is in Optimal status, it is first disabled prior to being re-created. This action invalidates the current snapshot.

Keep these important guidelines in mind when you re-create a snapshot virtual disk:

•To re-create the snapshot virtual disks correctly, follow the instructions for your operating system.

NOTE: Failing to follow these additional instructions could create unusable snapshot virtual disks. For more information, see the PowerVault Modular Disk Storage Manager online help topics.

•To use this option, the snapshot virtual disk must be either in an Optimal status or Disabled status.

•When using this option, the previously configured snapshot name parameters and snapshot repository virtual disk are used.

To recreate the snapshot virtual disk:

1In the AMW, select the Logical tab, select a snapshot virtual disk.

2Select Virtual Disk→ Snapshot→ Re-create.

3Type yes, and click OK.

Disabling a Snapshot Virtual Disk

Disable a snapshot virtual disk if one of the following conditions exists:

•You do not need the snapshot now.

•You intend to re-create the snapshot at a later time and want to retain the associated snapshot repository virtual disk so that you do not need to create it again.

•You want to maximize storage array performance by stopping copy-on- write activity to the snapshot repository virtual disk.

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.
