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

Using the simple path, the following defaults are used for the other parameters of a snapshot virtual disk:

Capacity Allocation — The snapshot repository virtual disk is created using free capacity on the same disk group where the source virtual disk resides.

Host-to-Virtual Disk Mapping — The default setting is Map now.

Percent Full — When the snapshot repository virtual disk reaches the specified repository full percentage level, the event is logged in the Main Event Log (MEL). The default snapshot repository full percentage level is 50 percent of the source virtual disk.

Snapshot Repository Virtual Disk Full Conditions — When the snapshot repository virtual disk becomes full, you are given a choice of failing write activity to the source virtual disk or failing the snapshot virtual disk.

Preparing Host Servers to Create the Snapshot Using the Simple Path

NOTICE: Before using the Snapshot Virtual Disks Premium Feature in a Microsoft® Windows® clustered configuration, you must first map the snapshot virtual disk to the cluster node that owns the source virtual disk. This ensures that the cluster nodes correctly recognize the snapshot virtual disk.

Mapping the snapshot virtual disk to the node that does not own the source virtual disk before the Snapshot enabling process is completed can result in the operating system mis-identifying the snapshot virtual disk. This, in turn, can result in data loss on the source virtual disk or an inaccessible snapshot.

For details on mapping the snapshot virtual disk to the secondary node, refer to the Dell PowerEdge™ Cluster SE600W Systems Installation and Troubleshooting Guide on support.dell.com

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

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.
