1Do you want to change the RAID controller module ownership of a virtual disk or a disk group?

•Change the RAID controller module ownership of a virtual disk – Go to step 2.

•Change the RAID controller module ownership of a disk group – Go to step 3.

2To change the RAID controller module ownership of a virtual disk, perform these steps:

a Select the Logical tab. b Select the virtual disk.

c Select Virtual Disk→ Change→ Ownership/Preferred Path. Alternatively, you can right-click the virtual disk and select Change→ Ownership/Preferred Path from the pop-up menu.

d Select the RAID controller module.

CAUTION: Possible loss of data access – If you do not use a multi-path driver, shut down any host applications that are currently using the virtual disk. This action prevents application errors when the I/O path changes.

e Click Yes.

The ownership of the virtual disk is changed. I/O to the virtual disk is now directed through this I/O path. You are finished with this procedure.

NOTE: The virtual disk might not use the new I/O path until the multi-path driver reconfigures and recognizes the new path. This action usually takes less than five minutes.

3To change the RAID controller module ownership of a disk group, perform these steps:

a Select the Logical tab. b Select the disk group.

c Select Disk Group→ Change→ Ownership/Preferred Path. Alternatively, you can right-click the disk group and select Change→ Ownership/Preferred Path from the pop-up menu.

d Select the RAID controller module.

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.
