•Snapshot Virtual Disk Name—A user-specified name that helps you associate the snapshot virtual disk to its corresponding snapshot repository virtual disk and source virtual disk.

•Snapshot Repository Virtual Disk Name—A user-specified name that helps you associate the snapshot repository virtual disk to its corresponding snapshot virtual disk and source virtual disk.

•Capacity Allocation—This parameter allows you to choose where to create the snapshot repository virtual disk. You can allocate capacity by using one of the following methods:

–Use free capacity on the same disk group where the source virtual disk resides.

–Use free capacity on another disk group.

–Use unconfigured capacity and create a new disk group for the snapshot repository virtual disk.

–Dell recommends placing the snapshot repository virtual disk within the disk group of the source virtual disk. This ensures that if drives associated with the disk group are moved to another storage array, all the virtual disks associated with the snapshot virtual disk remain in the same group.

•Snapshot Repository Virtual Disk Capacity—The snapshot repository virtual disk capacity is expressed as a percentage of the source virtual disk capacity. The maximum percentage allowed is 120 percent.

•Percent Full—When the snapshot repository virtual disk reaches the user- specified repository full percentage level, the event is logged in the Major Event Log (MEL). The default snapshot repository full percentage level is 50% of the source virtual disk.

•Snapshot Repository Virtual Disk Full Conditions—Choose whether to fail writes to the source virtual disk or fail the snapshot virtual disk when the snapshot repository virtual disk becomes full.

•Host-to-Virtual Disk Mapping—Choose whether to map the snapshot virtual disk to a host or host group now or to map the snapshot virtual disk later. The default setting is Map later.

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.
