When you create a snapshot virtual disk, you specify where to create the snapshot repository virtual disk, its capacity, and other parameters. You can disable or delete the snapshot virtual disk when you no longer need it, such as when the backup is complete. If you disable a snapshot virtual disk, you can re-create and reuse it the next time you perform a backup (see "Re-creating Snapshot Virtual Disks" on page 80 for more information). If you delete a snapshot virtual disk, you also delete the associated snapshot repository virtual disk.

NOTE: Deleting a snapshot does not affect data on the source virtual disk.

The information that follows will better prepare users for using the snapshot virtual disk premium feature of the Dell PowerVault systems.

NOTE: The following host preparation sections also apply when using the snapshot feature through the CLI interface.

Creating a Snapshot Virtual Disk Using the Simple Path

You can choose the simple path to create a snapshot virtual disk if the disk group of the source virtual disk has the required amount of free space. A snapshot repository virtual disk requires a minimum 8 MB of free capacity. The destination of a snapshot repository virtual disk is determined based on the free capacity available in the disk group.

If 8 MB of free capacity is not available in the disk group of the source virtual disk, the Create Snapshot Virtual Disks feature defaults to the advanced path (see "Creating a Snapshot Virtual Disk Using the Advanced Path" on page 73). In the advanced path option, you can choose to place the snapshot repository virtual disk in another disk group or you can use unconfigured capacity on the storage array to create a new disk group.

About the Simple Path

Using the simple path, you can specify the following parameters for your snapshot virtual disk:

•Snapshot Virtual Disk Name — A user-specified name that helps you associate the snapshot virtual disk to its corresponding snapshot repository virtual disk and source virtual disk.

Computer Drive specifications

Dell Computer drives are a crucial component of the brand's range of products, delivering reliable storage solutions tailored for various user needs. Dell offers a diverse lineup of drives, including solid-state drives (SSDs), hard disk drives (HDDs), and hybrid drives, each featuring distinct characteristics that cater to different performance requirements.

One standout feature of Dell's SSDs is their use of advanced NAND flash technology. This results in significantly faster read and write speeds compared to traditional HDDs, ensuring quicker boot times and application loading. With capacities ranging from 128GB to 8TB, Dell SSDs are ideal for both casual users and professionals who require consistent performance for data-intensive applications such as video editing, gaming, and large database management.

Dell's HDDs, on the other hand, remain a popular choice for users who prioritize storage capacity over speed. With options available in sizes from 500GB to 10TB, these drives offer users ample space to store large files, such as videos, music libraries, and software applications. Dell's enterprise-grade HDDs are known for their durability and reliability, making them suitable for server environments where data integrity is paramount.

Incorporating hybrid drives, Dell brings the best of both worlds. By combining the speed of SSDs with the capacity of HDDs, hybrid drives offer a balanced solution for users seeking improved performance without sacrificing storage space. These drives utilize a small amount of SSD storage as a cache to speed up frequently accessed files, enhancing overall system responsiveness.

Dell also emphasizes data protection in its drive offerings, with features like encryption and secure erase capabilities. This focus on security is vital for users in business environments, where sensitive information must be safeguarded against unauthorized access.

Another characteristic that sets Dell drives apart is their compatibility with a wide range of systems. Dell ensures that its drives can seamlessly integrate with various models, from laptops to desktops and servers. Furthermore, Dell's support for RAID (Redundant Array of Independent Disks) configurations allows users to configure their storage systems for enhanced performance, redundancy, or both.

In conclusion, Dell Computer drives encompass a comprehensive range of features and technologies that meet the needs of diverse users. With their emphasis on speed, capacity, durability, and security, Dell drives are a trusted choice for anyone seeking reliable storage solutions. Whether in personal computing or enterprise environments, Dell stands at the forefront of storage technology, continually evolving to meet user demands.
