NOTE: For details on mapping the snapshot virtual disk to the secondary node, see the Dell PowerVault MD3200 and MD3220 Storage Arrays With Microsoft Windows Server Failover Clusters on support.dell.com/manuals.

NOTE: You can create concurrent snapshots of a source virtual disk on both the source disk group and on another disk group.

Before creating a Snapshot Virtual Disk, note that:

•The following types of virtual disks are not valid source virtual disks:

–Snapshot repository virtual disks

–Snapshot virtual disks

–Replication repository virtual disks

–Target virtual disks that are participating in a virtual disk copy

NOTE: Virtual Disk Copy is an Advanced (Premium) feature.

•You cannot create a snapshot of a virtual disk that contains unreadable sectors.

•You must satisfy the requirements of your host operating system for creating snapshot virtual disks. Failure to meet the requirements of your host operating system results in an inaccurate snapshot of the source virtual disk or the target virtual disk in a virtual disk copy.

NOTE: Before you create a new snapshot of a source virtual disk, stop any data access (I/O) activity or suspend data transfer to the source virtual disk to ensure that you capture an accurate snapshot of the source virtual disk. Close all applications, including Windows Internet Explorer, to ensure all I/O activity has stopped.

NOTE: Removing the drive letter of the associated virtual disk(s) in Windows or unmounting the virtual drive in Linux helps to guarantee a stable copy of the drive for the Snapshot.

Before creating a snapshot virtual disk, the host server has to be in the proper state. To ensure that the host server is properly prepared to create a snapshot virtual disk, you can either use an application to carry out this task, or you can perform the following steps:

1Stop all I/O activity to the source.

2In the AMW, select the Logical tab and select a valid source virtual disk.

MD3600f, MD3620F 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.
