NOTE: For Linux, set the default gateway so that broadcast packets are sent to 255.255.255.0. For Red Hat® Enterprise Linux®, if no gateway exists on the network, set the default gateway to the IP address of the NIC.

NOTE: MDSM uses TCP/UDP port 2463 for communication to the MD Storage Array.

Automatic Discovery of Storage Arrays

The Automatic Discovery process sends out a broadcast message across the local subnetwork (subnet) and adds any storage array that responds to the message. The Automatic Discovery process finds both in-band and out-of- band storage arrays.

NOTE: The Automatic Discovery option and the Re-scan Hosts option in the Enterprise Management Window provide automatic methods for discovering managed storage arrays.

Manual Addition of a Storage Array

Use Manual Addition if the storage array resides outside of the local subnet. This process requires specific identification information to manually add a storage array.

To add a storage array that uses out-of-band management, specify the host name or management port IP address of each controller in the storage array.

Before using this option, verify that the applicable network configuration tasks have been performed.

To add an in-band storage array, add the host through which the storage array is attached to the network.

NOTE: It can take several minutes for MDSM to connect to the specified storage array.

To add a storage array manually:

1Select Edit→ Add Storage Array.

2Select the relevant management method:

•Out-of-bandmanagement—Enter a host name or an IP address for the RAID controller Modules in the storage array.

•In-bandmanagement—Enter a name or an IP address for the Host through which the storage array is attached to the network.

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.
