6Enter the snapshot repository virtual disks capacity as a percentage of the source virtual disks capacity and click Next.

The Preview window containing the summary of the snapshot virtual disk is displayed.

7Click Finish.

The Completed window is displayed.

8Click OK.

After creating one or more snapshot virtual disks, mount the source virtual disk, and restart the host application using that source virtual disk.

9In the AMW, select the Mappings tab, assign mappings between the snapshot virtual disk and the host that accesses the snapshot virtual disk.

NOTE: In some cases, conflicts might result from mapping the same host to both a source virtual disk and its associated snapshot virtual disk. This conflict depends on the host operating system and any virtual disk manager software in use.

10To register the snapshot virtual disk with the host operating system, run the host-based hot_add utility.

11To associate the mapping between the storage array name and the virtual disk name, run the host-based SMdevices utility.

NOTE: If your operating system requires additional instructions, you can find those instructions in your operating system documentation.

Creating a Snapshot Virtual Disk Using the Advanced Path

About the Advanced Path

Use the advanced path to choose whether to place the snapshot repository virtual disk on free capacity or unconfigured capacity and to change the snapshot repository virtual disk parameters. You can select the advanced path regardless of whether you use free capacity or unconfigured capacity for the snapshot virtual disk.

Using the advanced path, you can specify the following parameters for your snapshot 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.
