VSS attaches to the service and uses it to coordinate the creation of snapshot virtual disks on the storage array. VSS-initiated snapshot virtual disks can be triggered through backup tools, known as requestors. The VSS Provider Configuration Tool makes available the following configuration options:

•Snapshot Repository Virtual Disk Properties—This section contains a drop-down list for the RAID level and a field for entering source virtual disk capacity percentage for snapshot repositories.

•Snapshot Repository Virtual Disk Location—This section contains a list of preferences for the location of the snapshot repository virtual disk. These preferences are honored whenever conditions permit.

The Microsoft VSS installer service for storage provisioning is available on the MD3600f resource media in the \windows\VDS_VSS directory.

NOTE: When registering VSS during your Windows setup, the registration graphical user interface (GUI) prompts you to provide the name of your array because settings in the GUI are array-specific, not host-specific.

Storage Management VSS Hardware Provider Tips:

•The number of snapshot virtual disks that can be created using a single snapshot set varies with the I/O load on the RAID controller modules. Under little or no I/O load, the number of virtual disks in a snapshot set should be limited to eight. Under high I/O loads, the limit should be three.

•The snapshot virtual disks created in the storage management software are differential snapshots. Plex snapshots are not supported.

•Virtual disks to be used as source virtual disks for VSS snapshots should have names no longer than 16 characters. The VSS hardware provider uses the base virtual disk name as a prefix for the snapshot and repository virtual disk names. The resulting snapshot and repository names are too long if the source virtual disk name exceeds 16 characters.

NOTE: A volume is another term for 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.
