A learn cycle starts automatically when you install a new battery module. Learn cycles for batteries in both RAID controller modules in a duplex system occur simultaneously.

Learn cycles are scheduled to start automatically at regular intervals, at the same time and on the same day of the week. The interval between cycles is described in weeks.

Use the following guidelines to adjust the interval:

•You can use the default interval.

•You can run a learn cycle at any time.

•You can set the learn cycle earlier than the currently scheduled time.

•You cannot set the learn cycle to start more than seven days later than the currently scheduled time.

To change the battery settings perform these steps:

1In the AMW, select Storage Array→ Change→ Battery Settings. The Battery Settings dialog opens.

2In Battery location, select a battery.

3Check these details about the battery:

•Battery status

•Battery age

•Days until replacement

Setting the Storage Array RAID Controller Module Clocks

You can use the Synchronize RAID Controller Module Clocks option to synchronize the storage array RAID controller module clocks with the storage management station. This option makes sure that the event timestamps written by the RAID controller modules to the Event Log match the event timestamps written to host log files. The RAID controller modules remain available during synchronization.

To synchronize the RAID controller module clocks with the storage management station:

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.
