•If the storage array you are monitoring begins in or transitions to an unresponsive state, an informational dialog appears. The dialog informs you that the Performance Monitor cannot poll the storage array for performance data.

To monitor the performance of the arrays:

1Open MDSM and select the appropriate storage array.

2Open the Array Management Window (AMW) for the selected storage array

3In the AMW, select Storage Array→ Monitor Performance.

4Click Settings.

a Select the items that you want to monitor. You can monitor:

•RAID Controller modules

•Virtual disks

•Storage array totals

NOTE: By default, all items are selected.

bIn Polling interval, select how often you want to update the performance statistics.

NOTE: For an accurate elapsed time, do not use the Set RAID Controller Module Clocks option while using the Performance Monitor.

Each time the polling interval elapses, the Performance Monitor queries the storage array again and updates the statistics in the table.

5Click Start.

Values appear for the selected storage arrays in the Performance Monitor data table. The table is updated at the interval specified in the Polling Interval setting.

6Click Update to force an immediate poll of the storage array.

7Click Stop to stop monitoring the storage array.

8Click Save As on the Performance Monitor main dialog to save the currently displayed performance statistics.

9Select an appropriate directory.

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.
