3Select Change→ Copy Priority.

The Change Copy Priority window is displayed.

4In the Copy priority area, select the appropriate copy priority, depending on your system performance needs.

NOTE: There are five copy priority rates available: lowest, low, medium, high, and highest. If the copy priority is set at the lowest rate, I/O activity is prioritized, and the virtual disk copy takes longer.

Stopping a Virtual Disk Copy

You can stop a virtual disk copy operation that has an In Progress status, a Pending status, or a Failed status. Stopping a virtual disk copy that has a Failed status clears the Needs Attention status displayed for the storage array.

Keep these guidelines in mind when you stop a virtual disk copy:

•To use this option, select only one copy pair in the Copy Manager.

•When the virtual disk copy is stopped, all of the mapped hosts have write access to the source virtual disk. If data is written to the source virtual disk, the data on the target virtual disk no longer matches the data on the source virtual disk.

To stop a virtual disk copy, complete the following steps:

1In the AMW, select Virtual Disk→ Copy→ Copy Manager. The Copy Manager window is displayed.

2Select the copy pair in the table.

3Select Copy→ Stop.

4Click Yes.

Recopying a Virtual Disk

You can recopy a virtual disk when you have stopped a virtual disk copy and you want to start it again or when a virtual disk copy has failed.

The Recopy option overwrites existing data on the target virtual disk and makes the target virtual disk read-only to hosts. This option fails all snapshot virtual disks associated with the target virtual disk, if any exist.

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.
