Snapshot Virtual Disk With Remote Replication

A snapshot virtual disk is a point-in-time image of a virtual disk. In a remote replication, do not mount a snapshot virtual disk on the same server as the primary virtual disk.

Virtual Disk Copy With Remote Replication

The virtual disk copy premium feature copies data from a source virtual disk to a target virtual disk within the same storage array.

A primary virtual disk in a remote replication can be either a source virtual disk or a target virtual disk in a virtual disk copy.

You can create a virtual disk copy on the primary virtual disk in a replicated pair, but you cannot create a virtual disk copy of a secondary virtual disk in a replicated pair. Instead, you can copy a secondary virtual disk in one of two ways:

•Promote the secondary virtual disk to the primary role.

CAUTION: If a primary/secondary role reversal is begun while a virtual disk copy is in progress, the virtual disk copy fails and be unable to restart.

•Create a snapshot virtual disk of the secondary virtual disk, then perform a virtual disk copy of the snapshot virtual disk.

Virtual Disk Expansion With Remote Replication

Virtual Disk Expansion (VDE) increases the capacity of an existing virtual disk. This increased capacity is achieved by using the free capacity available on either:

•The disk group of the standard virtual disk, or

•The snapshot repository virtual disk.

Performing a VDE operation does not interrupt access to data on disk groups, virtual disks or physical disks.

A VDE operation can be performed on a primary virtual disk or a secondary virtual disk of a replicated pair. It cannot be performed on a replication repository virtual disk. No other action can be performed on a virtual disk while it is undergoing expansion (except normal disk I/O).

NOTE: To perform a VDE operation, the remote replication must be in Optimal status. The properties pane in the logical view displays the status of a virtual disk.

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.
