Out-of-Band and In-Band Management

You can manage a storage array in two ways:

•Out-of-band management

•In-band management

Out-of-Band Management

Using the out-of-band management method, data is separate from commands and events. Data travels through the host-to-controller interface, while commands and events travel through the management port Ethernet cables.

This management method lets you configure the maximum number of virtual disks that are supported by your operating system and host adapters. A maximum of eight storage management stations can concurrently monitor an out-of-band managed storage array. This limit does not apply to systems that manage the storage array through the in-band management method.

When you use out-of-band management, you must set the network configuration for each RAID controller module’s management Ethernet port. This includes the Internet Protocol (IP) address, subnetwork mask (subnet mask), and gateway. If you are using a Dynamic Host Configuration Protocol (DHCP) server, you can enable automatic network configuration, but if you are not using a DHCP server, you must enter the network configuration manually.

NOTE: RAID controller module network configurations can be assigned using a DHCP server (the default setting). However, if a DHCP server is not available for 150 seconds, the RAID controller modules assign static IP addresses. The addresses assigned are 192.168.128.101 for controller 0 and 192.168.128.102 for controller 1.

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.
