Re-creating Snapshot Virtual Disks

You can re-create a snapshot virtual disk that you have previously disabled.

CAUTION: Possible loss of data redundancy – If the snapshot virtual disk is in Optimal status, it is first disabled prior to being re-created. This action invalidates the current snapshot.

Keep these important guidelines in mind when you re-create a snapshot virtual disk:

•To re-create the snapshot virtual disks correctly, follow the instructions for your operating system.

NOTE: Failing to follow these additional instructions could create unusable snapshot virtual disks. For more information, see the PowerVault Modular Disk Storage Manager online help topics.

•To use this option, the snapshot virtual disk must be either in an Optimal status or Disabled status.

•When using this option, the previously configured snapshot name parameters and snapshot repository virtual disk are used.

To recreate the snapshot virtual disk:

1In the AMW, select the Logical tab, select a snapshot virtual disk.

2Select Virtual Disk→ Snapshot→ Re-create.

3Type yes, and click OK.

Snapshot Rollback

The snapshot rollback feature allows you to revert the contents of a virtual disk to match a point-in-time image existing on a snapshot virtual disk.

During a rollback, the host server can still write data to the base virtual disk. However, the snapshot virtual disk is set as read-only during the rollback operation and becomes available for write operations immediately after the rollback is complete. The snapshot virtual disk cannot be restarted, deleted, or disabled during the rollback operation.

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.
