3Click Log On.

4Select Automatically restore this connection when the system boots.

5Select Enable multi-path.

6Click Advanced and configure the following settings under the General tab:

Local Adapter—Must be set to Microsoft iSCSI Initiator.

Source IP—The source IP address of the host server you want to connect from.

Target Portal—Select the iSCSI port on the storage array controller that you want to connect to.

Data Digest and Header Digest—Optionally, you can specify that a digest of data or header information be compiled during transmission to assist in troubleshooting.

CHAP logon information—If CHAP authentication is required, select this option and enter the Target secret.

Perform mutual authentication—If mutual CHAP authentication is configured, select this option.

NOTE: IPSec is not supported.

7Click OK.

To support storage array controller failover, the host server must be connected to at least one iSCSI port on each controller. Repeat step 3 through step 8 for each iSCSI port on the storage array that you want to establish as failover targets. The Target Portal address is different for each port you connected to.

NOTE: To enable the higher throughput of multipathing I/O, the host server must connect to both iSCSI ports on each controller, ideally from separate host-side NICs. Repeat step 3 through step 7 for each iSCSI port on each controller. If using a duplex PowerVault MD32xxi configuration, then LUNs should also be balanced between the controllers.

The Status field on the Targets tab should now display as Connected.

8Click OK to close the Microsoft iSCSI initiator.

NOTE: PowerVault MD32xxi supports only round robin load-balancing policies.

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.
