Using Unconfigured Capacity

You can increase the capacity of a standard virtual disk or a snapshot repository virtual disk using the unconfigured capacity when no free capacity exists on a disk group. An increase is achieved by adding unconfigured capacity, in the form of unassigned physical disks, to the disk group of the standard virtual disk or the snapshot repository virtual disk. See "Disk Group Expansion" on page 135.

For more information, see the PowerVault Modular Disk Storage Manager online help topics.

Disk Group Migration

Disk group migration allows to you export a disk group so that you can import the disk group to a different storage array. You can also export a disk group so that you can store the data offline.

NOTE: During the export process (before the disk group is imported) you lose access to the data on the exported disk group.

NOTE: You must export a disk group before you move the disk group or import the disk group.

Export Disk Group

The export disk group operation prepares the physical disks in the disk group for removal. You can remove the physical disks for offline storage, or you can import the disk group to a different storage array. After you complete the export disk group operation, all of the physical disks are offline. Any associated virtual disks or free capacity nodes are no longer shown in MDSM.

Non-Exportable Components

You must remove or clear any non-exportable settings before you can complete the export disk group procedure. Remove or clear the following settings:

•Persistent reservations

•Host-to-virtual disk mappings

•Virtual disk copy pairs

•Snapshot virtual disks and snapshot repository virtual disks

•Remote replication pairs

•Replication repositories

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.
