Recovering From an Unresponsive Storage Array Condition

A storage array can have an Unresponsive status for several reasons. Use the procedure in this topic to determine a possible cause and solution.

MDSM can take up to five minutes to detect that a storage array has become unresponsive or becomes responsive again. Before completing this procedure, ensure that you wait some time before you decide that the storage array is still unresponsive.

To recover from an unresponsive storage array:

1Check the Tree View in the EMW to see if all storage arrays are unresponsive.

2If any storage arrays are unresponsive, check the storage management station network connection to ensure that it can reach the network.

3Ensure that the RAID controller modules are installed and that there is power to the storage array.

4If there a problem with the storage array, correct the problem.

5Perform one of these actions, depending on how your storage array is managed:

Out-of-band managed storage array—Go to step 6.

In-band managed storage array—Go to step 12.

6For an out-of-band managed storage array, ensure that the RAID controller modules are network accessible by using the ping command to ensure that the RAID controller module can be reached. Type one of these commands, and press Enter.

ping <host-name>

ping <RAID controller module-IP-address>

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.
