Modifying and Removing Host-to-Virtual Disk Mapping

You can modify or remove a host-to-virtual disk mapping for several reasons, such as an incorrect mapping or reconfiguration of the storage array. Modifying or removing a host-to-virtual disk mapping applies to both hosts and host groups.

To modify or remove host to virtual disk mapping:

NOTE: Before you modify or remove a host-to-virtual disk mapping, you must stop any data access (I/O) to the virtual disks to prevent data loss.

1In the AMW, select the Mappings tab.

2In the Defined Mappings pane, perform one of these actions:

•Select a single virtual disk, and select Mappings→ Change→

Mapping.

•Right-click the virtual disk, and select Change Mapping from the pop-up menu.

3In Host group or host, select the appropriate host group or host.

By default, the drop-down list shows the current host group or the host associated with the selected virtual disk.

4In Logical unit number, select the appropriate LUN.

The drop down list shows only the currently available LUNs that are associated with the selected virtual disk.

5Click OK.

Stop any host applications associated with this virtual disk, and unmount the virtual disk, if applicable, from your operating system.

6In the Change Mapping dialog, click Yes to confirm the changes.

The mapping is checked for validity and is saved. The Defined Mappings pane is updated to reflect the new mapping. The Topology pane is also updated to reflect any movement of host groups or hosts.

NOTE: If a password is set on the storage array, the Enter Password dialog appears. Type the current password for the storage array, and click OK.

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.
