To change the RAID controller module ownership of a disk group:

1In the AMW, select the Logical tab and select a disk group.

2Select Disk GroupChangeOwnership/Preferred Path.

3Select the appropriate RAID controller module slot and click Yes to confirm the selection.

CAUTION: Possible loss of data access– Changing ownership at the disk group level causes every virtual disk in that disk group to transfer to the other RAID controller module and use the new I/O path. If you do not want to set every virtual disk to the new path, change ownership at the virtual disk level instead.

The ownership of the disk group is changed. I/O to the disk group is now directed through this I/O path.

NOTE: The disk group might not use the new I/O path until the multi-path driver reconfigures and recognizes the new path. This action usually takes less than five minutes.

Changing the RAID Level of a Disk Group

Changing the RAID level of a disk group changes the RAID levels of every virtual disk that comprises the disk group. Performance might be slightly affected during the operation.

Guidelines to change the RAID level of a disk group:

You cannot cancel this operation after it begins.

The disk group must be in Optimal status before you can perform this operation.

Your data remains available during this operation.

If you do not have enough capacity in the disk group to convert to the new RAID level, an error message appears, and the operation does not continue. If you have unassigned physical disks, use the Disk GroupAdd Free Capacity (Physical Disks) option to add additional capacity to the disk group. Then retry the operation.

To change the RAID level of a disk group:

1In the AMW, select the Logical tab and select a disk group.

2Select Disk GroupChangeRAID Level.

3Select the appropriate RAID level and click Yes to confirm the selection. The RAID level operation begins.

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.
