About the Simple Path

Using the simple path, you can specify:

•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.

•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.

•Snapshot Repository Virtual Disk Capacity—The snapshot repository virtual disk capacity is expressed as a percentage of the source virtual disk capacity. The maximum percentage allowed is 120 percent.

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 Major 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

NOTE: 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.

NOTE: 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.

Configuration: Premium Feature—Snapshot Virtual Disks

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.
