Dell MD3600f Creating a Snapshot Virtual Disk Using the Advanced Path, About the Advanced Path

Page 152

After creating one or more snapshot virtual disks, mount the source virtual disk, and restart the host application using that source virtual disk.

11In the AMW, select the Mappings tab, assign mappings between the snapshot virtual disk and the host that accesses the snapshot virtual disk.

NOTE: In some cases, conflicts may result from mapping the same host to both a source virtual disk and its associated snapshot virtual disk. This conflict depends on the host operating system and any virtual disk manager software in use.

12To register the snapshot virtual disk with the host operating system, run the host-based hot_add utility.

13To associate the mapping between the storage array name and the virtual disk name, run the host-based SMdevices utility.

NOTE: If your operating system requires additional instructions, you can find those instructions in your operating system documentation.

Creating a Snapshot Virtual Disk Using the Advanced Path

About the Advanced Path

Use the advanced path to choose whether to place the snapshot repository virtual disk on free capacity or unconfigured capacity and to change the snapshot repository virtual disk parameters. You can select the advanced path regardless of whether you use free capacity or unconfigured capacity for the snapshot virtual disk.

Using the advanced 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.

•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.

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.
