Configuration: Premium Feature— Virtual Disk Copy

NOTE: A virtual disk copy overwrites data on the target virtual disk. Before starting a virtual disk copy, ensure that you no longer need the data or back up the data on the target virtual disk.

NOTE: If you ordered this feature, you received a Premium Feature Activation card that shipped in the same box as your Dell PowerVault MD storage array. Follow the directions on the card to obtain a key file and to enable the feature.

NOTE: The preferred method for creating a virtual disk copy is to copy from a snapshot virtual disk. This allows the original virtual disk used in the snapshot operation to remain fully available for read/write activity while the snapshot is used as the source for the virtual disk copy operation.

When you create a virtual disk copy, you create a copy pair that has a source virtual disk and a target virtual disk on the same storage array.

The source virtual disk is the virtual disk that contains the data you want to copy. The source virtual disk accepts the host I/O read activity and stores the data until it is copied to the target virtual disk. The source virtual disk can be a standard virtual disk, a snapshot virtual disk, or the source virtual disk of a snapshot virtual disk. When you start a virtual disk copy, all data is copied to the target virtual disk, and the source virtual disk permissions are set to read- only until the virtual disk copy is complete.

The target virtual disk is a virtual disk to which you copy data from the source virtual disk. The target virtual disk can be a standard virtual disk, or the source virtual disk of a failed or disabled snapshot virtual disk.

After the virtual disk copy is complete, the source virtual disk becomes available to host applications for write requests. To prevent error messages, do not attempt to access a source virtual disk that is participating in a virtual disk copy while the virtual disk copy is in progress.

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.
