•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.

•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.

Using the simple path, the following defaults are used for the other parameters of a snapshot virtual disk:

•Capacity Allocation—The snapshot repository virtual disk is created using free capacity on the same disk group where the source virtual disk resides.

•Host-to-Virtual Disk Mapping—The default setting is Map now.

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

•Snapshot Repository Virtual Disk Full Conditions—When the snapshot repository virtual disk becomes full, you are given a choice of failing write activity to the source virtual disk or failing the snapshot virtual disk.

Preparing Host Servers to Create the Snapshot Using the Simple Path

NOTE: Before using the Snapshot Virtual Disks Premium Feature in a Microsoft® Windows® clustered configuration, you must first map the snapshot virtual disk to the cluster node that owns the source virtual disk. This ensures that the cluster nodes correctly recognize the snapshot virtual disk.

NOTE: Mapping the snapshot virtual disk to the node that does not own the source virtual disk before the Snapshot enabling process is completed can result in the operating system mis-identifying the snapshot virtual disk. This, in turn, can result in data loss on the source virtual disk or an inaccessible snapshot.

NOTE: For details on mapping the snapshot virtual disk to the secondary node,

refer to the Dell™ PowerVault™ MD3200i and MD3220i Storage Arrays With Microsoft® Windows Server® Failover Clusters on support.dell.com/manuals.

NOTE: You can create concurrent snapshots of a source virtual disk on both the source disk group and on another disk group.

Before creating a Snapshot Virtual Disk, note that:

•The following types of virtual disks are not valid source virtual disks:

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.
