Using the Performance Monitor to retrieve performance data can affect the normal storage array performance depending on the polling interval that you set.

If the storage array you are monitoring begins in or transitions to an unresponsive state, an informational dialog is displayed. 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 ArrayMonitor Performance.

4Click Settings.

a Select the components 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 are displayed 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.

MD3620F, MD3600f specifications

Dell's MD3620F and MD3600F storage arrays are designed for businesses seeking dependable, high-performance storage solutions tailored to meet the demands of modern data management. These models offer a blend of scalability, efficiency, and advanced features, making them well-suited for a range of applications, from virtual environments to critical database operations.

One of the primary features of the MD3620F and MD3600F is their support for a hybrid storage architecture. This approach allows organizations to combine flash storage with traditional hard disk drives (HDDs) to optimize performance and cost. The MD3620F focuses heavily on all-flash configurations, delivering exceptional speed and lower latency, ideal for I/O-intensive workloads.

Scalability is another hallmark of these storage solutions. The MD3600F allows users to scale up to 120 drives, providing robust capacity to meet growing data needs. The MD3620F is engineered for environments where data availability and speed are paramount, with support for high IOPS (Input/Output Operations Per Second) and consistent performance under stress.

In terms of data management, both systems integrate with Dell’s proprietary software, which enhances operational efficiency through features like automated tiering. This technology optimizes data placement between different storage types based on access frequency, ensuring that hot data is readily available while reducing costs associated with less critical data.

Reliability is crucial for businesses that depend on their storage systems. The MD3620F and MD3600F come equipped with advanced data protection mechanisms, such as RAID support, which safeguards against data loss, and snapshot capabilities that provide point-in-time copies of data. Moreover, these solutions include hot-swappable components, ensuring minimal downtime for maintenance and repairs.

Connectivity is also a strong suit of these storage arrays. They support multiple connectivity options, including SAS and iSCSI, allowing for flexible integration into existing IT infrastructures. This adaptability enhances their appeal to a wide range of enterprise environments.

In summary, the Dell MD3620F and MD3600F stand out as robust storage solutions with a combination of hybrid and all-flash configurations, scalability, advanced data management tools, and enhanced reliability features. These characteristics make them ideal for organizations looking to enhance their data storage capabilities while maintaining high performance and efficiency.
